ABS on this truck is dangerous...

It's partly because people come in here and blame the driver for the issue. This issue, no matter what anyone says, is not driver error.

I'm not claiming to be the best driver out there. But I have plenty of experience of driving in snow/ice etc.. and with a plethora of different vehicles. With and without ABS. That's on hills, steep, not steep and completely level. A lot of hills around here. None of them have I experienced the "shit myself" stopping situations that I have found myself in like the Tacoma. Whether it be rear wheel, all wheel or front wheel drive. So its not like I have nothing to compare it to and in many different situations.

So with that said. Take it however you want. You may have not had this issue. Maybe you got lucky, maybe you're just awesome. But it's not something me and the others are just making up.

 

We will classify you as a semi-pro driver then! You have a lot of experience, more than an average driver, but haven't earned any special licenses yet

 

I don't think that shifting into neutral effects anything. I did a few snowy tests yesterday and confirmed that ABS is still activated when you shift into neutral.
I also hope that everyone that has had the ABS problems especially those who have crashed because of it reported the incident to Toyota, NTSB, etc. so that the issue can hopefully be resolved.

 

LOL. I'll take it. I'm gonna change my TW member description to semi-pro driver!

 

Plasma tires, it's what the cool kids rock.

 

I just wanted to post something that happened to me this week maybe it will help. First I have the electronics of my abs disabled and I have a mechanical (clutch style) lsd installed in my truck. On my way to work in 2wd I came around a corner and a car was backing out of a driveway and I had to stop quickly. I stabbed the brakes pretty hard and on a snow covered road stopped fast without the front wheels sliding, but as I was almost stopped the rear wheels on my truck started spinning and trying to push me. The rear of the truck slid sideways about 2 feet. Now I know if my abs was active I would have either slammed into that car or hit the guard rails on the other side of the street. So what does this prove. I believe that the abs problem is multi-tiered.

1. First the abs is way too sensitive
2. Second there is not enough brake pressure going to the rear wheels to be able to stop the truck safely in bad weather.
3. And last, why were the rear tires spinning. Was it that the torque converter stayed locked up longer than it should have. Or were the defrosters on and the ac clutch kicked in and raised the idle higher(I don't remember). Maybe there is a problem with the drive by wire system that at times creates a dangerous throttle hang condition.

Now on my truck I eventually want to pull the abs block and replace it with an adjustable proportioning valve to make sure this never happens again by increasing pressure to the rear brakes. This was the first time that this type of thing has happened since I disabled the abs back in Dec. 2012.

Also I wanted to point out that it was not a problem with my rear brakes as I use my e-brake every day and if my rear brakes were that far out of adjustment my e-brake would not work.

Hope this helps. Maybe someone smarter than I am can figure this abs problem out.

 

I think what he is saying is that there are multiple issues there.
Not only ABS is too sensitive but even disabled controls brake proportion ing.
On the top of the screwed up proportion ing we have drum brakes in the rear which is not helping.
Best resolution would be to rip abs out and install old fashion system.

 

Oh yea, right, buy new tires.

 

So you want drums on all four wheels with no power assisted braking.

 

You know what, fuck it. Let's just put airbrakes on the Tacoma. Then shit will lock up really quick.

 

With out abs? I would take even 4 drums. Most likely would stop faster too.

 

So enlighten me whats your theory on why so many people have problems with the abs on Tacomas. Everybody has bad tires and no one knows how to drive. I think I heard this all before.

 

At least someone got something out of what I was saying.

 

I think this could be a real possibility with the abs issue. Since my incident with the abs, i cannot replicate the way the brakes reacted on snow that time, whether jamming the brakes or coasting and applying brakes. Maybe there is a issue with decceleration? Because as others have explained, it was as if the brakes were just gone. After reading this post, i am remembering that it felt as if the truck wasnt even naturally slowing down...and without brakes working.
Since then, ive been testing brakes in snow, driving in a lower gear and being more cautious than usual.

 

I dont know I completely understand what Hugh posted. And knowing how ABS system works I know exactly what happened.
As the owner there are only two choices, leave ABS On and risk getting T-boned by 18 wheeler, or remove the darn thing and drive like before.
I disable my ABS when it snows, or just drive my car that has no ABS at all.
Smart ones with disable ABS in winter, stupid will think ABS is the best thing on the planet until they get t-boned by dump truck or snow plow.
Its natural selection .....

 

Ha ha. Semi's and Dump Trucks and Snow Plows OH MY!!

 

I did a little testing with my 2015 TRD O/R this weekend. Going down the driveway, which is currently covered in hard packed snow/ice, I tried hitting the brakes in various ways that I know used to set off the ABS problem in my 2007. I couldn't reproduce the problem with my new truck.

The ABS would still kick on, but I didn't feel like my brakes were gone, and the truck did stop in short order. It almost even felt at times like the ABS allowed the wheels to lock up a bit, but I can't confirm that.

On my 2007 in the same situation, it would give me a feeling as if my brakes were almost entirely just gone. I would start coasting down the hill, almost accelerating, out of control until I released the brake and tried again.

 

Foot buried into the brake pedal while in gear = bad move.

Shifting into neutral = good move. Then and ONLY then you bury your foot into the brake pedal.

 

This shift into neutral nonsense is insane. You should not have to shift into neutral to stop with an automatic transmission. This is not normal or safe. No other vehicles require this. If your driving down the street and a kid runs out in front of you then you slam on your brakes and stop. You do not think, oh let me put down my coffee and shift into neutral then I'll apply the brakes. Too late the kid is dead.
