ABS on this truck is dangerous...

The truth is ,each Tacoma ABS's obviously react differently. I've owned many vehicles from Jeeps,Trans-Am's ,Mach 1's to Acura's. The ABS brakes on my Tacoma were HORRIBLE! Doesn't mean everyone's act or react the same.

 

This issue is independent of tires. You can be on crappy tires, rolling at 5 mph and you stop 99% of the time. Than one time ABS will decide to mess with your zen.
Few things that I learned.
1. If you are in pickle because ABS kicked in, toss into Neutral. (it worked for me every time)
2. Release brake and pumped again and hope ABS will not kick in this time.
3. Have a weight on the back of the truck. That seems to get rid of the most crazy ABS behavior.
4. Or Disable bloody ABS because in the snow its useless anyway.

 

I was thinking that it would be great if there was a 'Snow' selector/pushbutton/transmission position, that when active would release the pressure from the torque converter when the brakes are applied. It would be like hitting the clutch. Nearly eliminate the need for ABS.

 

Don't try to use logic in here. ABS defies logic right?

 

ABS issue discussed in this thread has nothing to do with tires or their quality. You can have ABS work for you 99% of the time but than have 1% where it fails. Regardless of tires you have on.
Again ABS problem is independent of the tires.
Now better tires will make ABS activate less, but have no bearing on failure rate.

Let me explain to you this, in simple way.
If 50% of women slap you on the face after you ask them for a date, that means :.
Ask 2 women and one will slap you
ask 200 women and hundred will slap you.
Still 50% rate see its that simple, and your chance of getting a date is 50/50.

You can have winter blizzaks but if that time ABS decided to screw you it will happen. With blizzaks you will get less times that ABS needs to kick in but when it does your chances of hitting whatever is in front of you are the same as driving on Dunlops.
ABS issue is total independent of tires you driving on.

 

I'm going to have to go with DoorDing on this one, as the ABS does in fact use reed switches in each hub to determine rate of rotation at the hub. If a tire locks up or spins due to lack of friction/traction, then the ABS/TCS will activate.

Bad tires = Low friction/traction.

This can be aggravated by inflation pressure and lubricants between the tire and road/rock surface.

I cannot see how this relates to your sex life.

 

Yeah except you, DoorDing and bunch of others who think this is a tire issue are wrong.
I had ABS fail
on Dunlops
on Geolanders
and now on Blizzaks.
You can not get better winter tire than Blizzaks. Simply no tire will help to stop you if ABS is releasing brakes.
This problem is not with tires its a problem with crappy programmed ABS system.

 

Blanket statements on TW without any data to back it up. What is the world coming to .

ABS does not release the brakes. It modulates them. For whatever reason, mechanical or software, it is not effectively modulating the brakes for maximum stopping power while allowing the truck to steer on some Tacoma's. However, better tires will allow for better steering. Better tires also provide better traction which will give the system a better approximation of pavement, which seems to be what works best with our ABS.

However, heck, this is TacomaWorld so logic and science are worth two shits right .

 

So I have to recommend you have your VSC/ABS system serviced, perhaps you have a badly calibrated yaw sensor. I drive all over PA, year round, ice, snow, rain, mud, gravel and potholes, and have not had this experience with the ABS. I run Cooper Discoverer S/T in size 255/85/16 which works just as well on the PA turnpike at 80mph or chugging around Rausch Creek in 4-Lo.

 

When you figure out how ABS works let me know.

I doubt with out software change, calibration will help. Unfortunately Toyota gives no access to software so no way to find out what they screwed up. You can do calibration with Snap On tool but that does not help much. Its like once it goes beyond some hard coded limit it goes dum.

 

Ok. Those of us who have had issues with ABS have posted our issues, yet most those who have not had the issues come back with the BLANKET STATEMENT that it's the tires. Or the BLANKET STATEMENT that people don't know how to drive. If it didn't happen to you it didn't happen to me. Where's your data to back that up?

What? No data?

Are you asking for data on events that don't happen? Is this some kind of Schrodinger's Cat thing?
My perspective is that if the truck/powertrain is the same, the only differences are tires (prone to wear, different tread patterns and different inflation pressures), and the drivers.
Having put four children through college, I can guarantee you that all drivers are not the same, even if they have the same instructor.
Please stay on your meds.

 

I was pointing out that he has no data on whether the problem would get better with or without snow tyres. Are you saying snow tyres make vehicles have less traction? For the umpteenth time I'm not saying there isn't a problem. What I am saying is that, short of trading in the truck for something else, tyres are something that's easy to change to try and fix, or at least improve upon, the problem.

I don't know how you drive. Frankly I don't care if you do or don't disable your ABS, but I do care if some smuck here disables it and T-bones my pregnant wifes car because he couldn't steer out of an inevitable collision. Call me crazy that way.

Also, a few people recently have been complaining about the loss of both braking and steering, which is not what would happen if the ABS "let go". Rolling tyres should steer fine, and if they're not a tyre issue is likely part of the problem.

 

Ok

 

Smart plan. I wish I was that smart.

 

It's pretty easy to turn a T-bone type collision into a glancing blow where people are much less likely to be seriously hurt simply by steering and braking, rather doing just one or the other.

 

Nope. Wouldn't consider driving in the winter without winter tires. What is pissing me off in this entire thread can be summarized by Fifthwind's comment:

My perspective is that if the truck/powertrain is the same, the only differences are tires (prone to wear, different tread patterns and different inflation pressures), and the drivers.

It didn't happen to him therefore the problem doesn't exist. It's the tires or the driver. He does not see the possibility that there could be a programming error. It has to be the tires or the drivers. It didn't happen to him, therefore the problem doesn't exist. Never mind the fact that I am driving in Canadian winters for 35 years, and I currently have 3 vehicles in my driveway with ABS. Drive in Canadian winters for 35 years and you know (most know) how to drive in snow. I don't know how many vehicles I have owned with ABS, perhaps 10, maybe more. This TACOMA DOES NOT BEHAVE LIKE MY OTHERS. I have owned a Tacoma 4x4 before, and a 4Runner as well. Don't tell me the problem doesn't exist. It is real. Just because you don't have the problem, doesn't mean the problem doesn't exist.
