Mr Timmy My teacher introduced you to us in our Class In a Video 4Runner Timing Belt years ago Now here I am Instead of Being Mechanic I became a car design channel. Great video
What class were you taking when the instructor introduced you to our channel? I'm not sure I understand what an automobile car design channel is. Do you discuss what you would do to improve on existing vehicle designs?
The timing of this video is amazing. I’m looking to replace my brake booster on my 03 gx. My brakes feel ok (not GREAT I’d say), but more annoying is my buzzing/vibrating brake pedal every 3-4 presses. It buzzes on startup like it’s building pressure, but then it does it frequently when driving when using brakes.
@@TimmyTheToolman From my understanding from reading things and watching one of your other videos, it sounds like I need to replace the brake booster/pump (the cylindrical oil filter looking thing) and not the entire master cylinder. There’s a guy from the Lexus message boards who sells entire master cylinders rebuilt for $550... the booster I can get for $420... but, might be more cost effective to replace the whole unit all rebuilt vs just the booster?
The issues with this hydraulic brake booster is the hydro accumulator fails most times. It's a combination of both mechanical parts and electrical parts.1, Within the brake booster system there's a kind of thin film that gets punctured when you let your break system run low on hydraulic and it causes it to act like there's air within the system. 2, there's a hydro booster motor that spins anytime you turn on your vehicle and it can get noisy but as it ages it fails and it can causes the break pedal to loose pressure especially when you use it once b4 and you have to pump it up again to get break, that's because once you use the break, the booster motor fills up the accumulator again ready for reuse but because it fails it just looses pressure... which is what our friend here experiences. It's a nice system but I don't like it because when it fails, it's intrusive... unlike other Toyota abs designs that when they fail you still get servo breaking. Nice work Tim.... you're a legend. There are many things that could cause this too, amongst the plugs that go to the module one is a pressure sensor and that pressure sensor can fail and cause this same symptom too. Thos who haven't experienced this module failure wouldn't understand it's a very dangerous situation especially when you're on speed. Note when you were depressurising his system it didn't take much break actuation, that's because it never held pressure... it could also be an internal seal leak.... there's a whole plethora of possibilities but a complete replacement is the best shot.
Thanks for sharing all that. It sounds complicated. I've heard that people rebuild them, but from what you said, there's several potential causes, so replacing the whole unit does sound prudent.
I’m actually super glad I read your comment / just snagged a gx470 and this was recommended to me as something to replace - having had other ABS systems I assumed it was servo brakes as the default braking failure mode….. I’ll bump it up the list of “must fix” items
Love your detail Timmy and Tanh. I just did my 2004 and, what I think is the ECU and bracket get in the way on the left side when taking the 4 bolts off that hold the brake assy to the firewall. Had to get in there with smaller box end 12mm. The ratcheting style are nice in this spot.
Thanks! We're stoked you appreciate the detail this video offers the viewer. I love ratcheting box end wrenches. The flex head ones are awesome. Total game changer. If you don't have flex head ratchets with 120 engagement points, I highly recommend you get yourself a set of them. With them only taking 3 degrees to get to the next click point, it allows you to remove a bolt or nut in very tight quarters.
You are a Toyota God among men. I was watching an install of a 2nd gen Tacoma's Master cylinder. Different setup with a separate Booster, But, Is there an option for the GX470 / 4runners to add fluid into the master and bleed it prior to installing to make the bleeding process easier? (Plugging 3 of the 4 holes and on the 4th hole have a tube recirculating the fluid back into the master while pushing the plunger in and out to remove air, then switching to the other 3 openings to bleed as well? Maybe to eliminate the need for TechStream? Slightly more messy of course. I bleed the brakes on GX470's (Caliper Swaps, Longer Steel Braided lines) a lot and don't need TechStream and wonder if there is a way to not use it for this install as well.
My experience with the GX470 brakes is pretty limited to the videos I've done. I've heard of different methods to bleed the brake booster without the use of Tech Stream but I haven't tried those methods. I know with standard master cylinders with a separate brake booster, you can bleed it of air before doing a general bleeding of the braking system at all 4 wheels.
Now I'm just going to think about those slivers on the end of the brake lines I didn't check for until I pull them all off again. Didn't think of checking that, good tip.
It might not be as big of a deal that I make it out to be but it's been something I've noticed when working with brake lines and fuel lines. I figured it would be best to make sure the flared tubing end was clear of debris before reassembly to limit the chance of a leak.
Thank you so much for putting in all the extra work to provide a great video for all of us to reference. I had a Q and sorry if I missed it in the video or comments. Did you do any bench bleed or filling of the new system before installing? Thank you again.
You're very welcome. No, there wasn't any bench bleeding involved. We cover everything you need to know in the video to perform this swap. Happy Wrenching!
Thank You for such a detailed video with thorough explanations. I have a hissing noise coming out of my brake paddle and each time it hisses the brake booster motor works and I feel the vibration in my foot through the brake paddle. Also, I hear a suction and whistle noise when I start my car it goes away in 1 minute, and then when I turn off the engine another suction sound comes loud from the engine. I tried to locate a vacuum line leak but I couldn't find one in the hoses and around the intake manifold. I am stressed and I am afraid that my brake booster motor is going to fail if this hissing noise keeps going on. Please help!!!
It certainly sounds like an issue with the brake booster. I've heard you can buy rebuilt ones for a more affordable price but I haven't tried to source who sells them.
@@TimmyTheToolman Thank You so much for your reply. So I should just replace the brake booster or is there a way to find the leak and try to fix it? I live in Houston Texas, If you can recommend me any places to take the car to may be they can figure it out for me?
@@RizwanRizwan-bd9su I don't know how you'd find the leak. I would just rebuild it with a kit but I don't know if they still make a rebuild kit for it. When we did the job, Thanh said he found out Toyota no longer makes a rebuild kit for it, but maybe an aftermarket supplier does offer a kit. Like I said in my other response, I think people sell rebuilt brake boosters. Do a search with the part number we provide in the video description and I bet you'll find a rebuilt one for a much more affordable price than new. I wouldn't have a recommendation for a shop in Houston.
There are no vacuum hose connections to this type of brake booster. It's all electronically controlled. You're thinking of a different type of brake booster that uses vacuum from the engine.
This system uses an electric pump to develop high pressure fluid for power assist for normal stops and ABS braking. No vacuum is connected at all. That's why this system is so dangerous because when the pump motor fails, not only do you lose power assist, you also lose all rear braking. This system has been around since the 80s. It's German and was used in foreign and domestic brands. The domestic brands got smart and ditched it back in the early 90s. Can't believe Toyota used it into the 2000s. If you pay attention to how often and long the pump is having to run and replace the accumulator when it becomes to frequent or long, you will extend the life of the pump. I believe this one was leaking internally or had a bad main or dump valve though. He was having extended pedal travel.
Great Video Timmy. Do you know if this is the exact same procedure for a 2004 4runner limited V8? I got the trac light, vsc light, brake light and the buzzing alarm noise inside. My limited 4runner is very similar to the gx470 without all the Lexus bells and whistles. Is the bleeding process the same? It seems to make the most sense to replace the entire unit since I have 287K on my rig.
I'm not sure it's the same because we've never done this job on a 4th Gen 4runner. I'm assuming it would be very similar but I don't want to steer you wrong and say it's the same when I'm not sure.
It's the same procedure whether it's a 1986 Pontiac/Buick, 1990 Ford/Lincoln 1992 Land Rover or a 2000+ Toyota/Lexus or any of the other Various brands that used this German junk.
Have a 2002 Toyota 4Runner, ABS and Brake light on dash come on along with a very loud high pitch alarm that’s constant. Still had brakes for a couple days. Moved the truck a couple days later at my house and brakes went out, stiff pedal and barely came to a stop even at a low speed of 5-10 mph. Went to start up the truck a couple days later to let it run and dash lights and alarm went away and had brakes again after a minute or two. Drove truck around the yard to confirm and had brakes again. Went to start it today and lights and alarm came back on but still have brakes at the moment. Ever run into anything like this? From what little research I’ve done it’s pointing to brake booster/abs pump module which is supposed to be one unit on this year 4Runner. Just confusing that I lost the brakes then started working again. If you get around to this comment, just wanted to say thank you too. Never had much experience working on vehicles and your videos have helped me a lot in the past.
It does sound like your brake booster has gone bad. They are very expensive, unfortunately. There's a guy in Washington that parts out 3rd and 4th Gen 4runners. He might have a used one he can sell you. His name is Josh Young, and his company is PNW Connection. Tell him Timmy the Toolman referred you. facebook.com/josh.young.3950?mibextid=ZbWKwL
How did you get the pin back in? I know you didn’t show it but I am having no success am I have lost the pin twice trying to blindly slide it in place.
It's not comfortable but you have to get your head under there to see what you're doing. I utilize a headlamp so I can use both my hands and still see what I'm doing. So, I wasn't blindly sliding it in place. I could see the pin sliding through the pedal and the brake booster plunger. If you haven't dropped that lower interior trim panel, that might help.
The program is called Tech Stream. I bought it pre-loaded on a laptop that I bought from an Ebay seller. I don't think he's selling them anymore. There's official and unofficial ways to obtain the program. Here's a link to the official way by buying a license to use it: techinfo.toyota.com/techInfoPortal/appmanager/t3/ti?_nfpb=true&_pageLabel=ti_home_page&contextType=external&username=string&password=secure_string&challenge_url=techinfo.toyota.com/techInfoPortal/login/techinfo&request_id=-5518364760491963150&authn_try_count=0&locale=en_US&resource_url=https%3A%2F%2Ftechinfo.toyota.com%2F I'll let you do the research on the unofficial ways to obtain the program and license to use it.

You need a windows based operating system. I bought a used laptop on Ebay just so I can use Tech Info to look up FSM information I need. I pay $20 for a 2-day subscription and download all the information I need.
Look up Toyota Tech Stream and you'll figure it out. I bought a laptop on Ebay with the program already installed. You'll find the cable for sale on Ebay and Amazon sites.
What’s everyone doing if they don’t have tech stream? I’ve put my new unit it and I’m trying to bleed the brake booster assy using the how to hbb video but the two front lines facing the front of the car aren’t bleeding, no fluid is coming out where the other three there have been no problems.
Thanks Timmy! Lots of people watch your great videos, so hoping. But will take it to a shop if I can’t get it. Appreciate your quick response. Your videos are amazing!
Not from Thanh's experience. It was a sinking brake pedal for the most part. Listen to the beginning of the video and you'll hear Thanh explain the brake experience he had.
Mines gave up the unit cost a whooping 2000 dollars at the dealer. I'm sad bought this 4runner a couple years back. None of the mechanic want to use a refurbished unit all wants new. Anyone nice enough to help out that lives socal?
You can use the link we provide in the video description and get an Aisin one for $500 and swap it out yourself. The video walks you through what you need to do.
I appreciate the video, im not mechanically inclined but the video is a great resource. The Aisin part is new to me however i type the part number on google and its showing me the toyota part. Is there a specific link to get the aisin that is 500? Thanks for the video sir.
The cost of the brake booster use to be around $2500. Now you can pick it up for around $1500. Don't know how many hours of labor this would bill for. And, every shop will have different hourly labor rates.
Well Mario, I did a simple Google search which you could have done as well to get some answers. The following is what I found out. The 32 Code means a problem with your left front speed sensor. The sensor plugs into the steering knuckle. Examine the sensor and the wire to see if there's any damage. The 52 Code means ABS pump motor is locked, open in pump motor ground. I read it could be a grounding problem which is affecting the voltage to your ABS pump. Check the connections at your battery and clean them. Check the ground wire connection at the driver side fender. Check the ground on the engine block near the driver side engine mount bracket. The 56 Code means there's an Accumulator low pressure malfunction. The accumulator is part of the hydraulic brake booster (aka Master Cylinder). It might be your hydraulic brake booster is bad. That's what I got for you Mario. I've never diagnosed the issues you're having so this is the extent with which I can help you out. Good luck.
Mostly because the person said something that annoyed me, pissed me off, or was disrespectful. If the person is a real jerk, I permanently hide their comments from being seen by anyone other than themselves. Why do you ask?
@ingridis111 That's weird. If it was deleted, it was a mistake then. Go ahead and repost it. Sometimes RUclips puts a hold on comments thinking they are spam and wait for the content creator to approve of it. A lot of the time, the comments are perfectly fine so I don't get why the comment was flagged.

What’s everyone doing if they don’t have tech stream? I’ve put my new unit it and I’m trying to bleed the brake booster assy using the how to hbb video but the two front lines facing the front of the car aren’t bleeding, no fluid is coming out where the other three there have been no problems.
I don't know how many people are going to see your question. I would suggest possibly going to a shop that has tech stream to do the bleeding for you.
Thanks Timmy! Lots of people watch your great videos, so hoping. But will take it to a shop if I can’t get it. Appreciate your quick response. Your videos are amazing!
@@AR-xu2gg Ok, good luck!
how different do you think a 2015 gx 460 is?
Not sure Leo. Never worked on one. It's probably similar based on what I know about Toyota.
I replaced one of those on a Lexus GS350 because booster was grinding. The booster was $2,000. from the dealership
Yeah, they're expensive part to replace.
When these fail, do you get a total loss of braking?
Not from Thanh's experience. It was a sinking brake pedal for the most part. Listen to the beginning of the video and you'll hear Thanh explain the brake experience he had.
Thank you!
You're welcome!
Thanks man
You're very welcome. Thanks for commenting.
Mines gave up the unit cost a whooping 2000 dollars at the dealer. I'm sad bought this 4runner a couple years back. None of the mechanic want to use a refurbished unit all wants new. Anyone nice enough to help out that lives socal?
You can use the link we provide in the video description and get an Aisin one for $500 and swap it out yourself. The video walks you through what you need to do.
I appreciate the video, im not mechanically inclined but the video is a great resource. The Aisin part is new to me however i type the part number on google and its showing me the toyota part. Is there a specific link to get the aisin that is 500? Thanks for the video sir.
@@harold6716 Sorry, I was totally thinking of another video I did on a GX470. As far as I know, you're right, you can buy new or get a rebuilt one.
big job what's the cost
The cost of the brake booster use to be around $2500. Now you can pick it up for around $1500. Don't know how many hours of labor this would bill for. And, every shop will have different hourly labor rates.
Good Morning ! 👍

I have 4runner 2001 with abs problems
I gets codes 32, 51,56 you now what’s means?
Well Mario, I did a simple Google search which you could have done as well to get some answers. The following is what I found out.
The 32 Code means a problem with your left front speed sensor. The sensor plugs into the steering knuckle. Examine the sensor and the wire to see if there's any damage.
The 52 Code means ABS pump motor is locked, open in pump motor ground. I read it could be a grounding problem which is affecting the voltage to your ABS pump. Check the connections at your battery and clean them. Check the ground wire connection at the driver side fender. Check the ground on the engine block near the driver side engine mount bracket.
The 56 Code means there's an Accumulator low pressure malfunction. The accumulator is part of the hydraulic brake booster (aka Master Cylinder). It might be your hydraulic brake booster is bad.
That's what I got for you Mario. I've never diagnosed the issues you're having so this is the extent with which I can help you out. Good luck.
@@TimmyTheToolman THANK YOU !!

Tim, why do you delete comments?
Mostly because the person said something that annoyed me, pissed me off, or was disrespectful. If the person is a real jerk, I permanently hide their comments from being seen by anyone other than themselves. Why do you ask?
@@TimmyTheToolman My comment that one can buy a replacement piston for the master brake cylinder as a remedy for this exact issue disappeared
@ingridis111 That's weird. If it was deleted, it was a mistake then. Go ahead and repost it. Sometimes RUclips puts a hold on comments thinking they are spam and wait for the content creator to approve of it. A lot of the time, the comments are perfectly fine so I don't get why the comment was flagged.
Great
👌🏼
