Brakes Malfunctioning - Turning off.

Did you have Toyota reset vsc after you lifted? Could the yaw sensor have made it go crazy in the middle of the turn? I know it turns off in 4lo, but like traction control, doesn't it turn back on at a certain speed? Worth looking into.

 

Wow dude glad to hear your ok, that could have hurt you. Let us know what the insurance company finds out, something tells me they should pay out or Toyo should right? Freaky.

 

Complete failure of the ABS will not stop the brakes from working.

 

Thats funny considering how brakes are made to allow you to stop. I would say that if abs causes your brakes to altogether stop working the evidence is contrary to what you say.

 

And the truck has sat at the shop for a week. Every time i call they say "its the next one gonna be looked at" said that 5 times...

 

Im not a fan of the sliding down a hill brakes wont engage because of abs thing. Made a down hill right hand turn at 3 miles and hour and hit Ice. Brakes would engage and Id almost stop then disengage. I almost died. Hope your truck gets fixed.

I can take some later. Not anything major thats for sure.

 

Do you really think any manufacture would relay on an electrical part to stop a vehicle in case of some thing a small as a fuse or an ABS motor failure? No your vehicle will stop even if the ABS completely failed.

 

No because you can pull the ABS Fuse killing power to the ABS Controller and the brakes still work. Proof Positive what he said is true.

 

ABS on Tacoma = Sucks

 

Disable it.

 

Haven't looked at your truck in a week of it sitting at the dealership? I'd go shit on the service managers desk.

 

Well if you do get it back it's pretty easy to disable the ABS with a switch. I've put close to 200k miles on second gens and have had WAY too many close calls due to the ABS. I put the ABS relay on a switch on the last two and I shut it off whenever i'm driving in the snow or off road. I have other cars with properly functioning ABS that can stop in snow no problem. But once these activate the ABS it doesn't matter how hard you push the brake pedal they just DON'T STOP!

Of course a failing master cylinder feels very much the same. Just last night I came off an exit ramp kinda hot and went to nail the brakes and got nothing. Pumped the pedal once and it stopped perfect. Did it 3 more times on the way home. No fluid loss anywhere and I just put 2 new calipers on it. I'm going to pull the wheels and check it out more closely tomorrow for leaks but I'm pretty sure the master has had it.

 

This is what I plan to do. I bought the switch a couple days ago.

 

The brakes are hydraulic the ABS is electrical it is the hydraulic system that stops the truck not the electrical system. The ABS does not apply the brakes you do; it is your foot that applies the pressure. How about all the people that by pass the ABS their trucks still stop. If the ABS was doing all the work then every time you step on the brakes the motor would run it doesn’t. Loosing brakes is all most nonexistent in modern vehicles and pretty much only happens with age and usually just ½ of the system. Losing breaking traction on icy roads is very common ABS or not.

 

This how a properly functioning ABS system works. One wheel slips and it lets off brake pressure for that wheel. But Toyota's system in the Tacoma seems to seriously overreact and pulse all wheels instead of just the one. There is a puddle that forms at the end of my road right next to the stop sign. About 3 feet across and 10 feet long. In my truck if the ABS is on and that is icy I will roll out into the street when I come to the end of the road EVERY TIME. If I switch off the ABS sure the right side wheels slide a little but I come safely to a stop before the stop sign, not in the middle of the road where I could be t-boned by traffic. Oddly enough my 25 year old BMW with ABS stops me before the sign no problem. So does my wife's Venza. So did our old 00 4Runner. The ABS in these trucks just flat out sucks. One of these days I'll figure out how to disable it without having the stupid warning light on and I'll finally not worry about stopping ever.

 

It will only pulse the one that is turning slower than the others at that instant it may cycle any of them or even all of them depending on wheel speed and traction it is a 4 channel system. I will agree the ABS is sensitive on the Tacoma but the bottom line you are in charge if it engages let up on the brake and reapply but don't hammer it that will surly apply the ABS.

 

The times I've experience the overly sensitive abs have been when applying normal pressure to the brakes. Not slamming or pushing harder. The most recent was the left tires were on bare pavement and the oright tires on snow. When I applied the brakes to slow down the abs went into drama mode and the truck just kept going. I've tried releasing and reapplying the brakes, but it doesn't help.

It's also been my experience that it doesn't over react every time I'm in a slippery situation. Sometimes it will act like a normal abs vehicle and other times it will over react and the truck won't slow down.

 

basically just did the same thing going down hill from my house, no brakes, took it to low (auto trans) stepped on e-brake...nothing. Turns out a rear brake line rusted through. This should not prevent the rear e-brake from working but on such a steep grade the rear drums will not do much even if adjusted to almost drag.

Its so obvious you have never had this happen. The abs can override the hydraulic system in order to pulse the wheels. Pulsing is turning brake pressure on and off very fast. Turning off. These trucks just so happen to seem to keep them off. The brakes literally stop working for no reason. Stop trying to act like you know what you are talking about. Most vehicles shouldnt have a problem but these trucks obviously do. Plus. No ice in hawaii dude.
