had an oh crap moment today.

Make that, you don't know who YOU are talking to.

Which doesn't matter either way. Facts are independent of who is delivering them.

 

now now, play nice

 

There are two main types of modern ABS systems: three and four channel. Three channel systems control the braking pressure on both front wheels independently, but control the rear wheels together as a single unit. Four channel systems (as shown in Diagram 1) control the brake force on each wheel independently (assuming you're in a four wheeled vehicle!). In three channel systems, although both rear wheels are monitored by sensors, if wheel lock if detected on a single wheel the hydraulic braking pressure is reduced equally on both wheels. This does not provide the level of control of a four channel system, and thus three channel versions are compromised and usually only fitted to cars to save on cost. Most modern cars now use a four channel ABS systems which provide greater safety in emergency braking conditions.

Thank you for your post.

 

Well, i can say that the panic brake assist works good. Had a lady cut me right off this morning and i had to slam the brakes. I heard the abs activate and felt the truck brake even harder than what my input was. Pretty neat.

 

You had another quote of "know your facts."

I know my facts ... search this thread for my posts.

ABS on this pickup has worked very well in some situations for me... very well and pulsed and reacted as I would expect ABS to.

AND IN OTHERS IT HAS NEARLY KILLED ME - the only reason it didn't is I consider myself a good driver and had to react to a new situation of no brakes and steer safely out of this. Like the fellow with 29 years - I have probably backed up more miles than others on here have ever driven.

I can make it fail under the "right" situatuions. It always takes a combination of a bump and loose road material - snow, slush, gravel etc. When it truly fails for me however THERE IS NO PULSING FEELING of the brakes even trying to function - impotent is the best description.

To the dude who suspects black ice - in your shoes I also would suspect it and respect your question. However it was non - existent in some of my experiences; yes I know how hard it is too see - I was driving on it today.

Personally - install the little switch. Use it when you recognize conditions that OUR ABS is likely to fail in and move on. To all others who do not want to go that route I offer my prayers for a safe ride and the suggestion of opening your mind to the option that perhaps yours has not failed in a similar way .... YET.

 

If you disconnect your ABS via switch you could possibly be charged if you got into a seroius accident that caused injures or death. If you really think there is a problem take the truck back to your Toyota dealer. Toyota is fanatical about safety.
