Just change front brakes pads and speed sensor on 2005 Tahoe LS and now abs, t/c and e brake light stayed on. As before the abs and t/c light would come on once in a while. Why does lights stay on now is my question?
+Erick Martinez Solis We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Will this work on a 18 Chevy is making the same thing and noise ?
Thank you it fixed my truck doing this

I tried this and it worked on my 2005 Silverado (4x4)! I took my truck to the shop to replace the wheel hub from the passenger side. After I picked up the truck from the shop, the ABS activated at slow speeds. There was no light on the dash though. It felt that the ABS was activating on the driver's side. I took the truck to be diagnosed and they told me there were no codes. So I took it upon myself to check the sensor on the driver's side. I followed the instructions on this video. When I inspected the sensor I noticed that it was a little detached. I took it off and cleaned it real well. I also sanded the place where it went. I sprayed a little paint. After I put everything back together, I test drove the truck and the ABS no longer activated! Thanks to this video, I was able to solve the issue!
IA auto treated this application with intricate detail. Not many mechanic shop are willing to engage in these crucial disciplines.
This is a great video for eliminating a small problem before you go and buy a $500 ABS module.
All thanks to your video I fixed my 99 toyota solara. Most of the Auto shops doesn't know what it was. And I spent lots of money changing wheel sensor, master cylinder and pads any many more. Once again thanks be to your video I fixed my car on my own.
Parts company giving repair instructions that didn't involve new parts... That plus how useful the info was (although a bit too detailed for me, could have been much) compelled me to give it a like.
+charinabottae Thanks for the feedback!
That piece you called a "gasket", "plate", then "washer" is a shim. Some have more or no shims at all. If you remove all the rust and the abs still comes on, try removing a shim or two. The O ring is the "gasket" that keeps out debris. Great videos!
Thank you! Having this problem in my 2003 rape van
You’ve just become my favorite person ever. Thank you so much for making this comment because I have been struggling for two months to fix my suburbans ABS issue. I am proud to announce that your comment is the reason why my vehicle is no longer kicking in the ABS when I come to a stop
Is that how you fill for the airgap?... do you know where to get them?
You nailed it!! Took two shims out and it’s gone!
Thanks for your supplement
I put a pair of MOOG front hubs on my 1997 GMC suburban K1500 back in 2019 and the ABS started acting up this month. After thoroughly cleaning the surfaces, everything worked fine. There was a shim on each side that I cleaned and reused as well with no ABS activity.. Thanks for the great post and advice.
Thank you for this fantastic resource. It was very helpful. I will keep you in mind for any parts needs in the future.
Well done video, always a pleasure to have a professional giving up his/ her time to make a video on how to do a repairs. Thank you..
Thank you for this video 1A Auto I literally spent months trying to diagnose this issue. I replaced the booster, and the master cylinder until I came across your video.
This worked!!!! Fixed the annoying slow speed ABS false activation issue.
On my Express van, ABS on passenger front wheel was activating right before vehicle comes to complete stop, pulling steering to left. Now it's fixed.
You guys saved my life. Iv bin to the break shop 4 times and still didn't get it right 👍 . You guys rock
I'll try this on our 08 Uplander! Thanks for the great video
Thank you so much for this video. I will do the same process because my ABS light comes on everytime it rains and I noticed that it came from when I sprayed my front driver side Tire it turned my signal on. So I'm going to be safe and replace the Hub and the wheel speed sensor. Thanks for doing this video and it was straight to the point and the video was clear

Just replaced a faulty sensor on my 2003 GMC Savana thanks to you. My sensor was so stuck it came out leaving the sleeve and o-ring behind. I used a 5/16 tap to get a grip on the sleeve so that I could extract it by pulling on the tap with no damage to the bore. Excellent video! The problem is fixed.

One of the best presentations I've seen.
Professional, concise explanation and excellent camera work. We need more presentations at this level. Thankyou.
I have this issue on my 2005 Chevy Tahoe. I just pulled the ABS 60amp fuse and that fixed the problem. Maybe someday I will clean the sensor,,,but for now Im good. Also you said 100ft lbs pf torque for the lug nuts...Im pretty sure its 140ft lbs is the correct spec for the lug nuts...good video!!!
Absolutely awesome well here’s to hoping that that fixes it as my 2002 Chevy avalanche Z 66 had a similar issue and the brake light was just dying because the previous owner just disconnected the plug
Finally a video telling exactly everything I need and how to do it. Thank you!
+Lukeamania Thank you for your positive feedback! We are happy we could help.
@@1AAuto I know you're supposed to do both sides but I was running out of time and only got the driver side done yesterday. About to go do the passenger side now.
Did it work?
Awesome video! Our work truck has been in and out of the "shop" with this problem so my company finally let me work on it I just followed this video step by step and fixed it without many hold ups except the seized up caliper hanger bolts

Awesome video, really helped me diagnose the issue with my vechile. Cheers
A good and well made video. Thanks for sharing this instruction!
Great video so clear and precise THANK YOU so much....
Did this for my equinox and it still acts the same, probably just faulty sensors at this point, but this video did teach me how to locate the sensors, thanks.
Update?
Try resetting your vehicles CPU either by disconnecting battery or with a scan tool that’s able to perform such action.
Just did this on my 2006 silverado 2500hd. It worked😊. A couple of comments: 1. If the truck is old enough to have this problem, you will probably break off the sensor sleeve when you remove it. The plastic sleeve will break off and stay in the hole in the hub. Don’t despair. Use some needle nose pliers to pull out the sleeve and throw it away. If the sensor itself is not damaged, get some liquid electrical tape and paint it all around the sensor and it’s tip. Let it dry for two hours before you reinstall it. To make sure water doesn’t get into the hole, get some plumbers putty and spread it around the base of the sensor before you reinstall it. Finally get a lock washer that is just big enough to fit over the Allen bolt. This will make sure that the Allen bolt presses the plastic sensor assembly tight against the hub where you filed and sanded away the rust. I’ve had this problem on a 1995 Yukon and my 2008 Silverado. Both when the hit their 8th year on the road. Poor design my gm. Thanks so much for making this video. It will help many people.😊

Okay so I've been following you guys for quite a while. I've been doing this 28 years and I cannot figure out this low speed ABS activation. It's usually when pulling up to a stop sign or a red light weather the steering wheel is straight or slightly turned the ABS pump kicks in and the service stabiltrack comes comes on the display. It is a 2008 Chevy Express 3500 regular cargo 6.0 l. I have replaced the front hub assemblies with new sensors and the two rear sensors with the AC Delco pigtail kits as well , I have also replaced fuses and relays just in case , inspected wiring to the module for the ABS and I was told that the only two things left are the steering wheel position sensor and the brake switch that could be causing this. Like I said I am a huge fan of you guys and hope you have more knowledge on this because I can't track down this problem that is freaking out the drivers in my fleet. HELLLPP
Thanks for the info ended up being a bad hub but you pointed me in the right direction
Hi. Very informative video. I have my brakes that are randomly locking too fast, especially at very low speed, causing blocking the wheels, even if I push very lightly on the pedal. And sometimes, almost no brakes. My Chevrolet Express is becoming dangerous... Should this ABS speed sensors being the issue? Thanks for you help.
Thanks for the video but I have a question. How do ill adjusted sensors cause a spongy pedal and did this fix the problem?
Excellent job explaining this procedure and good camera work to see everything clearly. I learned a lot. Thanks so much...I think I've got the same problem that comes on at slow speed when I'm coming to a stop in my 2002 GMC Safari. Looking forward to more good videos from you.
I wish I had seen this video first.
Had a similar problem on my 02 Chevy S10 Blazer. Previous owner let the passenger side front brake get to Bare metal on the inner pad.
Diagnostic tool said "erratic signal/no signal from passenger side front sensor, and that set an ABS DTC light.
Upon inspection that sensor wire looked cut or just the casing was loose at the sensor.
I bought 2 news ones to replace both. Had to clean out some metal shavings stuck to the magnet in the sensor. Wasn't rusty on that side so I didn't clean the mounting surface by file or emory cloth. Now I get the low speed abs activation, but no codes set.
I'll check the driver's side sensor mounting area for rust when I replace that sensor, and go back over the passenger side and clean out any more metal shavings with compressed air & brake cleaner.
Then coat both mounting surfaces with a rust inhibitor.
I’ve been having this issue myself thank you for the awesome video you probably save me a ton of money do you have a new sub!!!!!👍👍👍👍

Same here. None of that um, ah, kinda, stuff. Very professional explanation and and excellent camera work. Thankyou.
exact same thing happening to me on my 2005 silverado ! thanks for video
Great video. Directly to the point. It worked on my 98 Bravada. Thanks!

Just wanted to point out that if these are active sensors, they require a good electrical ground especially where the sensor mounting screw base metal collar contacts the metal wheel hub. Removing all the rust will resolve a poor ground issue if the issue is rust at the point of contact between the ground collar/ mounting bolt collar and the hub. Either way (active or passive sensor) always clean the mounting surface of any rust.
Excellent I’ve been looking for the reason my brake pedal gets soft right before I stop then kicks back when I need the brakes the most/. I’ll try this first thank you.
One of the best I've seen!
+Ted Hounsell Thanks for checking us out! 1AAuto.com
2002 Tahoe LS having pulsing when stopping at low speeds. I is not my front disc/brake pads I replaced those a year ago. I rather just replace the front abs speed sensors and clean out the abs hub. I am not getting any abs notifications via "Check Engine" light when it is on so sensors (oem) might be good but it is a 2002 so rather just replace it. Gonna follow this kat's video. Thank You.
Thought this video and explanation was very well done. One thing is, I thought the surface of rotor that touched the rim is rusted, so I assume there is corrosion on the inside of the room. My preference is to clean the surfaces up also.
Thank you for this. Mine started doing this a couple months ago and I've been thinking about it a lot. Sad part is, I just replaced the rotors, calipers and and pads a week ago and that would have been the perfect time. First decent day I will try this.
+Mike Milam Thank you! We love empowering our customers and showing how to perform DIY auto repairs with our high-quality auto parts. 1aau.to/m/Shop-1AAuto-c
Did you fix it yet and did it work for you ?
@@nickbriones6106 I had same thing it started with a rusted dripping brake line then I replaced calipers hoses and mastercyclinder though I had no ABS light lite up on dash panel but after putting Master cyclinder on I have a ABS lite on and it going to the floor what is wrong with 06 Silverado I’m going crazy
Great Video, my compliments to the mechanic...
+glmoore001 Thanks for checking us out! 1AAuto.com
I bought 2 brand new hubs with sensors from you guys. Trick still doing the same thing.
@@NSDflug most gm trucks need a scanner to bleed the brakes for abs
very detailed video, thank you for putting in the effort to share your knowledge with everyone. I believe the rear sensors can do the same thing. I had this issue on my 2007 GMC envoy and ultimately replaced both front bearing assemblies with Delco brand parts, now I'm focusing on the rear because after inspecting them I see that they have the same issue as the fronts. The rear sensors go right into the axle assembly. Am going to pull them and clean them up, reinstall.
+ditttch Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I remember GM had aTSB for this. Only difference is the bulletin said to use dielectric grease.
Great video. 2003 Suburban…needed to remove the shim completely to get it fixed.
Beauty Clark!!
Very informative. Good job explaining how it's done and what is what. Nice job.
I have a 2001 ford ranger that this seems to be happening to. The left wheel seems to be breaking free compared to the right. Gonna have to check this out. Great stuff and thank you.
+Rocker Thanks for checking us out! 1AAuto.com
Thanks for all you guys do, back yard mechanics are almost a thing of the past, but you guys are making us a bit more confident again, I’m glad I can wrench on my 99 Tahoe, love that truck. Buying parts from you guys is so easy to do and reasonably priced, thanks for all you do. 😎
Thank you so much for the video!
Great video. Easy to follow and very detailed. I did both front sensors and it solved my problem of low speed ABS activation on my 2002 Chevy Silverado. The ABS doesn't activate at low speeds BUT the ABS light now comes on and stays on. Anyone know if it needs to be reset or I actually do have an ABS problem now. Your thoughts will be greatly appreciated.
Run the scanner on it. See what codes say
+Wayne Ramsey Thanks for checking us out! We do recommend getting your vehicle professionally diagnosed.
check your ABS 60amp fuse...a blow fuse will also cause the ABS light to stay on. If the fuse is blown your ABS will not engage and wont cause low speeds and the ABS light will stay on. Good Luck
Mine does the same thing I think it's the driver side as that's where I can hear the sounds of the caliper but I replaced sensor with new one same issue
Great job guys!
+Roger Rivera Thanks for checking us out. 1AAuto.com
Great video.....fixed my low speed ABS but wish I had a lift. Lol
Thanks for checking us out. 1aauto.com +Marley Mayfield
My 2004 Silverado does this. Gonna go through both sides and do what you did here to see if it fixes the abs issue. Getting tired of it engaging at low speeds on dry road
finally. rebuilt my breaks new booster. new master cylinder (replaced 2 times in one month) pep boys couldnt find why it messed up in slow speeds. bleed the lines 4 times.. still couldnt figure it out. this vid may finally have giving me the hint as to why it doent feel safe at slow speeds.. thanks. will work on it.
i have a '95 Chevrolet g20 van
great information.keep in mind if someone recently replaced the wheel bearing with a cheap one it ma be leaking grease and causing the same problem with the sensor as in my case
+Anthony Jones Thank you for your feedback!
Please explain more.
I followed the procedure exactly to get rid of the constant abs activation in my 2004 Tahoe 4x4. I even used a couple spritzes of spray paint, as recommended. On the driver's side, I had the little flimsy metal gasket but on the passenger side, there wasn't one but the sensor was of a different brand (not sure if that explains it). I just put everything back together rust free and no more clicking. Liberal use of brake cleaner is key to make the cleaning easy of the hub and sensor.
Thanks. Other videos didn't give ba good explanation. Tomorrow I will work on my Subaru. But didn't get the type of spray you used
Found my way here because this happened to me today, nearly drove my Tahoe through the front window at NAPA. Couple of nut hairs away from cracking glass. Never happened before today. Relay pulled until I can properly repair it.
Great How to Video, Thank You
+Brian Loney Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I thought the spec on the caliper mounting bracket to the hub is 40ft.lb? Either way there is plenty torque, no axial load on the bracket only shear load. Great video was thinking of doing just this however replacing the entire hub doesnt seem to pricey. Are there any tricks to removing the CJ joint from the hub or is it just a centre bolt holding it to the spindle??
That’s sounds like the slider bolts that hold the caliper onto the bracket. Bracket bolts are 133ft lbs
2005 f150 fx4 4x4 with a 5.4. I have break pulsation only at low speed. If it is abs activation will the abs light come on? cause i have never seen it and with that year does it even have the light sensor?
So this will fix my pedal getting stuck and my truck not stoping on traffic stops? I have new calipers and booster. I don’t need to repair my abs module or pump?
You doing very good job 👍👍👍👍👍

Yep that exactly what was wrong ,clean surface till shiny and fix problem.
Did exactly what you did I even replaced the sensor still have the problem any ideas
Great video. I guess this is my issue. 2008 Chevy Express 1500 2WD. Braking on low speed(coming to a stop)I feel a vibration pushing back on the pedal(pedal kick back) and soft brake pedal feel, is this the ABS kicking in? The feeling is like when your car skids on snow and pedal kicks back on your foot. Thanks for the help, I'm looking for a reputable mechanic in my are(though job). North Jersey.
you are right,bad speed sensor will do that.
I have the same and it is abs ring cracked on my
Roberto Ortega was it the sensor or hub?
Hi Mike so the squeaky noise when stopping is the abs engaging
Great informative video
+lingnine Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Thanks for the video, I had a guy do my breaks and after that the stabilitrak and traction control started happening. I may need a new sensor.
+Candyman Thanks for checking us out! 1AAuto.com
I have replaced the front wheel bearings with new sensors. The brake pedal does exactly this……there is a stainless shim and a brass shim under the sensor mount. There is also a brass sleeve thru the sensor mounting hole to be used as contact. Should I remove the shims to close the air gap??
I have a question. 2009 chevy traverse . New abs module , new abs sensors on both wheels. Abs light WAS on before new module. Now it's off. Abs was still activating under 20mph. With no abs light on the dash. Before the new module it was activating the abs at any speed. After new abs sensors it now does it under 20mph. I was looking into the input/output transmission speed sensors but have NO CHECK ENGINE LIGHT and NO abs light on the dash any more. Can you give me any advice on where to look without just blindly throwing parts at it?
Question I've replaced one wheel speed sensor now having this problem on the side which was replaced. I noticed after inspecting both front tone rings the side I replaced the sensor on the gears look dirty compared to the other side. Could this be the culprit.
I have this same problem, I replaced the abs sensor but it didn’t fix the abs problem. I’m going to have to take it apart again and do a better job cleaning the rust. Thanks for the video.
+Gl0ck93 Glock93 Thank you!
1A Auto Parts just an update, fixed my abs problem thanks to you guys from 1Auto! I used a dremal rust remover bit since there was a lot of rust. It did the job! I live in the north east where salt is heavily used on the roads. Thanks again, you saved me money!
Thank you for the feedback! +Gl0ck93 Glock93
Gl0ck93 Glock93 did it fix your problem or??
Where does that shim come into play?... how do you know if you need any and where can you get them?
First off the proper tourque is 120 ftp on wheel lugs and should have been tightined a minimum of twice at half and then full I personally prefer doing it in three steps to final tourque believe it or not improper tourque of lug nuts on a setup like that one is number 1 cause of rotor warpping believe it or not but absolutely true also your only supposed to use electrical parts cleaner on sensor not brake parts cleaner unless certified for electrical parts as well you also didn't put any locktite on bracket bolts nor any antiseaze on sensor bolt or hub face to keep rotor from corroding to the hub and you didn't clean out the sensor hole and your not supposed to sand near the sensor or it's mounting holes as the magnet in the sensor can pickup the magnetic particles including the microscopic ones and can a rune sensor altogether even a brand new one can be runed like that
No issues with the paint or the brake cleaner going into the hub assembly?
Thank you for this video I'm gonna do it to my 2005 Chevy z71 pick up
What was your problem? Calipers hold at stoplight?
i changed both side wheel bearing last week but i still ABS will active at stope sign and slow speeds... can you please let me know what is the issue then? i have no code on ODB reader form anything
just replaced my wheel hub assembly on my 02 sonoma, which comes with a brand new speed sensor. didn't have this issue before replacing it, which was a super rusty original part. any suggestions as to cause?
Nice job! Very precise, to the point, informative, but yet short! Thank you.

Are there ABS sensors on the back wheels on a 2004 Sierra ?
.
Thanks learn a lot
Sir I have 2009 Toyota highlander
ABS work so quickly even in the rain and little bit snow
Even I put snow tires but they help little bit
Do you Think If I clean that rust and follow your Vedio
It can solve my problem or no
Thanks in advance
Even I am thinking to pull out ABS fuse.
Installed two new wheel bearings from 1a auto, which come with new wheel speed sensors. Replaced rear speed sensors with 1a sensors. Still having the same issue
I am getting a magnetic encoder malfunction after wheel bearing swap. I reset the error and drive slow and I can feel that low speed ABS kick in on braking and then after a few of those, ABS light without the low speed ABS brake feel now. The scanner doesn’t say the sensor is bad so I’m going try and take it out and clean it. If I can’t get out cleanly will just manhandle and will just replace. The bearings are not backwards, the tone ring is facing in towards vehicle. I hope this is it and I don’t have a damaged bearing.
Use scanner to bleed abs
Would this work on a 04 tahoe
I have a 1997 gmc jimmy when the ball joints went bad while under warranty the dealer cut the wheel speed sensor wires instead of unplugging them. They repaired the cut with simple wire connectors. When those corroded the ABS system would activate without much brake pressure but it just cycled the fluid inside the ABS valve removing all hydraulic pressure to the wheels. Giving complete brake failure. It surprised me because I actually worked at the TRW plant in Fowlerville MI where these systems were made. They told us any failure in the ABS system would result in the system returning you to just standard brakes. Unfortunately this is not true. Luckily no one was hurt. I since replaced the backing plates with new wheel speed sensors. These new ones started rubbing inside the rim and the same thing happened again. Now I just leave it unplugged.
+Charles Ronk Thanks for checking us out and sharing your feedback! 1AAuto.com
Is it OK to use brake parts cleaner on plastic and electrical connections?
1998 k1500 replaced both sensors and cleaned surfaces, kept the old shims on each side and still getting the abs issue where it activates at low speeds, should I remove the shims or something else I’m not doing right, any help would be great
Was it still doing the same thing when you drive it ?
When I make sharp right turn while pulling into a parking spot and I press the brake it starts to make clunking noise. And the abs light comes on as well. Could that be the problem due to sensor?
Great tutorial. Thank you. Why would you not want to put grease in the sensor when installing to make sure rust does not form in that hole in the hub? The older version of 1A Auto installing sensors showed them apply grease to the sensor upon installation? Does it really matter?
No grease needed, the hub that the sensor mounts into is a greasy atmosphere. The main concern is painting the mating surface.
Have a 2002 gmc sierra, I have replaced power Booster and Master Cylinder, front calibers and rotors. But the issue I'm having is that when trying to drive in parking lot and pull in a space I loose bark pressure and have to push all the way to floor and hope it stops
I have an ABS that is activating at low speed on my Sierra.
I'll give it a try, thanks.
+motokev Thanks for checking us out! 1AAuto.com
Did it work?
figured out I needed to replace an abs sensor. thank you. other issue. front brakes won't release after driving for a bit and get up to 260 degrees. truck works hard to go down the road like I'm holding the brake pedal down. caliper pistons are free and float nicely. new rotors pads, d.s. caliper, and flexible brake lines. (thinking the brake lines were the culprit) I've read it could be the booster, master cylinder, or abs. do you have any video's on this problem?
+brett mccafferty We may have a video for your vehicle. Could you please provide us with your vehicle information?
2005 chevy Silverado 1500 5.3 extended cab front disk rear drum RPO brake code JF7 4x4
You can check to make sure your rubber brake lines are not breaking down internally. They will swell up actually holding the pressure on the calipers making them not release. Rarely it could also be a bad master cylinder that is leaking pressure through the lines.

Thank you I will try it right away. My ABS light only goes on in city. Goes off on the Freeway.
