- I finally fix the ABS light on my Volvo 740, after testing the sensors and checking resistance, it turned out to be a hidden fuse all along, but then after some test emergency stops I experience severe brake failure...

I love how old cars reward you when you fix them by having something else break!
It's a great relationship isn't it 😂
Oh they had the sensitivity to wait you fix one thing to throw another, instead of breaking all together 😅
Probably best if you don’t mention it to the Mrs….they can be very sensitive about tiny details like brakes 😂
Well crap! Isn't that the thing with these cars, fix one thing, something else goes. Can't wait to see the next video!
That's exactly what I thought 😂 I can never get the 'to do' list down below a certain size
Ha, that's exactly why you always fix at least two things at a time. Even if it's just applying some contact spray or grease somewhere. Gotta stay ahead of it :D
I know how you feel when the fuse fixed the ABS. For over a year the gearbox on my 940 would drop out of fourth down to third and stay there. Recently a wise Volvo mechanic said it was probably the overdrive relay. I bought one for 80 bucks. Plugged it in, gearbox works fine, I was so pleased. The old one did not have any apparent damage. It's a great feeling when the old Volvo starts working again like it should.
Well what a cliff-hanger Sledge! If you died RIP. If you didn't die see you in the next one. I should keep this a secret from Ms Involvo'd. She might get a bit cross with you.
Well damn I was all ready to look for that fuse, now I think I will leave it alone. ABS light has been on since I bought it. 😅
Ah, the joy of failing brakes, and the lovely feeling you get, when you push the brake pedal all the way to the floor and nothing happens. And i do hope that you and the Volvo are ok.
Thanks! First time I've experienced it and hopefully the last 😅
That's a really nice paint color. Yes, fix "this" in order to find out "that" doesn't work.. it's climbing the ladder to success! 1988 eh? .. just getting broken in.
Right on!
On a lot of those older Volvos with electronic speedometers, it's often shoddy wiring down to the speedometer sensor on the differential. Sometimes, the sensor fails, too.
Thank you for risking life and limb to bring us these videos.
It maybe worth cutting a hole in the floor pan so you can use your feet to stop the car, it seemed to work for the Flintstones!
Haha, this is the car that already had huge holes in the floor pan when I bought it, should have left it that way!
I had the same issue with my 240, had driven it for years with the abs light on. I thought that a battery issue I had, had killed the abs pump or something. So I didn’t might looking at it. My fuse wasn’t broken put after putting a fresh one in, it had fixed the problem. Then the wire on the axle broke and no speedometer and no abs again haha.
Dir wird nie langweilig mit einem alten Volvo. Es gibt immer was zu tun 😁
Genau 😂
The old Volvos are Masterpieces and the Red Block lasts forever, If regular oil Change is done. They are nearly perfect and easy to Work on. The Problems with the Instrument- Cluster is well known and If they Had Just wired the Instruments instead of using that plastic foil, there will be No Problems att all. Nearly perfect....anyway, this is such a Solid and reliable Car, you can't find this quality today
I hope you didn’t die. We’ll, not unless Miss Involvod is going to keep the channel going 😝
Master brake cylinder issue.
Exactly 👍
haha what a cliffhanger, looking forward to the next one hope you didnt die
Bloody hell.
Hope all is ok now. In the other hand I’m too familiar as well with the “one thing fixed and another one breaks soap opera”.
RIP brother thanks to miss involvo'd for uploading this, will she now be taking over the channel?
I wish 😂
What a good tip of this subscriber. Oh no. What happend with the brakes? 🙈 just finished rebuilding a seized caliper. Tomorrow up for MOT. Wish me luck.
Awesome dude. I live in Littleton New Hampshire and I watch you videos all the time. I recently inherited a 1993 240 Volvo wagon from my Mom and it runs excellent. I've replaced Every fluid all new brakes all new sensors water pump voltage regulator both fuel pumps and mostly all the bushings
If you managed to upload this video and are replying to comments then I guess you didn't die! lol
What a cliffhanger! Hopefully I won't experience brake failure. I splurge on new brake parts to start with a brake system in a known condition. On my Amazon, I even went as far as replacing all the brake lines to be 100% sure.
That's definitely the best policy 👍
What a cliffhanger! 😂
Hi, just off topic, the car wizard channel has an in-depth look at the volvo 262 bertone.😊
I will check it out, thanks!
Time to borrow a couple of nappies aff the wee yin. 😂
🤣
Derek never worries about brakes, they’re only an afterthought as a rule….. good job sorting it though fella. Just tell Mrs Involvo’d you didn’t see anything…
Now I know how he feels when he approaches those intersections with no pedal 😅
Derek's a menace on the highway! I'm very glad that I don't live anywhere near Tennessee!
Probably the brake master cylinder that failed when it got higher pressure than usual from you trying to lock the brakes.
And the speedo problem, if you have a 3 pin speedo you should try to find a yazaki cluster from 87-88.
They usually work, even the fuelgauge
Thanks
Hopefully it's just overheating fluid due to age. Good Luck.
I remember mine having a warm start problem when I first got it. It would flood itself and the only way to get it started was to remove the plugs and crank it dry. It did it one night in the pissing rain and while trying to start it I noticed a load of sparking around the dizzy cap … it was tracking all over the place. Once replaced it was much better until the fuel regulator startedleaking fuel into the manifold . Have a look at it running in the dark for jumping sparks
Awesome
such a great feeling when you fixed an issue
Good news on the ABS front. Hope you managed to stop with the gears and handbrake! Look forward to next video. I'm sure your OK.
It probably took you more time to take the bulb out of the dash than to change this fuse.😂
But this is easy talking afterwards.
Yeah true 😂
Would be nice if that was the problem with 93 240 always worth a try!
Ahh, brake test time and the master cylinder fails. (or maybe it was a brake hose) Coincidental but still frightening/annoying. I have replaced masters on EVERY Volvo I've owned as one circuit will fail. Currently, my 1970 appears to be going down that road and I'll likely need to switch it out within the next few months. It doesn't feel quite as strong as I'd expect on hard stops.
Oddly it doesn't seem to matter if it is Girling or ATE. Whatever the specification Volvo had these companies build them to isn't the most robust long term. Dunno why that should be since it isn't like the master design wasn't used by other manufacturers, you'll find visually similar/identical ATE and Girling masters on SAAB, BMW, AUDI, NSU, etcetera of my cars era.
Since the 740 borrowed mechanically a lot from the 240 (and the 240 from the 140) it is little wonder it comes with that model lines idiosyncrasies.
That's why it is a triangulated system though, a failure probably won't put you in the ditch. Plus you still have the emergency hand brake. BTW, if you've not done so, try a few gentle and then aggressive practice stops with just the handbrake to get an idea as to how it behaves when used to stop the car at speed. For drums, they work ok though they take way longer to retard to a stop as one might imagine.
Thanks, yes it was the master cylinder, it wasn't the firmest pedal before, I think in future I'll replace them too especially with how old they are at this point
Ah that is just perfect... :')
I've never had any issues with my speedometers on my volvos, although my fuel level metre never works. As this video came out im guessing you're alive?
Old cars just keep giving don't they lol
These cars have a serious form of autophobia, never show any sign of relief when you are in its proximity😉
😂😂😂
Mastercylinder or external leak
I don t have AbS in nt 740 gle 1884,neither katalisator
I don't remember exactly, but when you bought the car, did it have a dead speedometer? You didn't change the alarms and then it worked or was it the silver 940 and here the alarms worked from the start and it just died now?
People who complain about scotch locks are the people that don't know or use them, either on the wrong type wire or if they are fitted poorly or where water can get at them, they are like any other type of connector, they are designed for there own certain things, let's face it how long has that scotch lock been in your volvo? Has it ever let you down yet? No because you have used it in the right place an fitted it properly!
Like all things in life it won't work if your using it incorrectly!
That's a good point, this scotch lock was already fitted when I bought the car, but when I replaced the fuel sender I refitted it because it worked 😄 I don't see a big problem with them to be honest
Did you sort out the warm start rough idle issue??
No still not sadly!
Burst pipe from the emergency stops?
the double loop system would've kept the front axle and one of the rears working.. well, at least that's what it was designed for.
But that doesn’t exist on ABS cars.
@@PV_240 oh, that might be true. I assumed it was the same with or without. But yeah you must be right, it doesn't have 2 ABS blocks, does it?
It was the master cylinder, the emergency stops must have finished it off!
@@Tasmanian_D3vil You meant to say "all without have a 2 circuit system" right?
I have the same issue with my 245. ABS light is on solid. My mechanic couldn't find a fix after replacing sensors. So I removed the bulb.
Where would that fuse be on a 240?
I'm not too sure to be honest, I think there might be one under the passenger seat but there should be some diagrams online that pinpoint it exactly. Hopefully it is just a fuse 🤞
Did the fluid overheat due to the brake tests? When was the fluid last replaced? Scary.
It was the master cylinder that failed, it wasn't the most firm anyway and those hard stops finished it off!
@@Involvod Glad to find out on a test drive that the master cylinder was about to explode rather than on a regular Sunday cruise with the family on-board.
@@martij30 exactly!
Either you died and someone else uploaded the video or your all good 😏
Well damn. Blew an old line?
the car has a double brake loop system. One of the rears and both fronts should've kept working if only one pipe burst.
@@Bassalicious Yeah you're right
@@username.858 actually I might be wrong. I just learned that ABS cars apparently don't have that system and I guess there's only a single pipe to the ABS block anyway.
@@Bassalicious That wouldn't make a lot of sense but could be possible
It was the master cylinder that let go! Didn't like those emergency stops 😬
Blow a line with all that excited stamping?
Turned out to be the master cylinder!
I mean, bummer that you died.
Welp, time for babyinvolvo'd to take over already.
ok, lets think about this. you published this video so you must be alive.......hmmmm. (truly hope you and the car are ok).....
Thanks 😉
For whatever reason, the RUclips algorithm suggested this old video about a 740 hot start issue. I'm sure you've seen it already but here's the link just in case. Seems like just the kind of issue that would drive you nuts trying to track down: ruclips.net/video/hMdot4GK_24/видео.html
Thanks!
@@Involvod Sorry, now I remember you said you have the hall effect sensor so I doubt this helps. Sigh. The symptom just seemed so identical.
RIP in Pepperoni
