Poll on total brake failure in 100 series (8 Viewers)

[PADDO]

Voted no, coming up to 150k miles, '03 LX. For those asking for some sort of system health check or test. I ran the FSM bleeding routine, section BR4 of the 2004 manual and noted the following:
Accumulator recharge time is listed as approx. 30 to 40 seconds. I timed my recharge times at 26s x 3 tests.
Discharging the brake accumulator I felt a very distinct difference in pedal feel (hard to very soft) at 19 or 20 pedal pushes, this gels with what I've read somewhere that said we had about 20 brake pedal pushes before the accumulator discharged.
Measured 11mm difference in brake fluid reservoir height from charged to discharged.
Techstream brake ABS bleeding appears to achieve exactly the same outcome as using the elusive sst magic box when you follow the FSM japenglish routines.
HTH.

No, 2006 @183k miles...

I am a little worried however, since my VSC Trac, Trac Off, and ABS light this weekend. I had fully functional brakes, and the lights turned off, so I chalked it up to a wheel speed sensor.

no 99 with 109K

No for my LC 02 which I had from 33.5k to 110K until totaled, and no again for my LC 06 which I got with 65K and still have with 80K (I can't vote twice but perhaps the poll administrator can adjust for that.) Both were Toyota certified used with good service records.

Wow as someone who has trusted his life and the lives of his family members to the UZJ100 for the last 10 years this is really a sad situation - the fact that there have been no fatalities can be attributed to a combination of a) total loss of brakes is a very rare occurrence and/or b) LC/LX drivers are much better than average. Given no action from Toyota or the Feds and our investment, financial and otherwise, in these vehicles it all really comes down to two things: preventive maintenance to prevent this from happening, and knowledge of what to do if it does happen. The latter question has already been answered (e-brake, downshift, pump hard,) the former (unless acknowledged by Toyota) will be determined by the collective wisdom of this community.

we all know we have a great vehicle; I just wish there was some sort a precautionary maintenance that can be done with out total replacement of the MC/abs system rebuild etc. I need new pads on my front soon so I'm gonna try to bleed my brakes once kids are off to school and I have some spare time

looks like the votes are trending "no" pretty strongly so far. Mine is a 2000 with around 150K (I cant remember off the top of my head)

Since this thread is centered around trying to determine the statistical probability of a brake failure on 100s, I went back and read all of the posts again to see if I could discern a trend. Based on my review - and, given the fact that I have no idea what is contained in the data gathered in the poll, here's what I discovered from the 107 posts above this one:

• There are 11 personal accounts of failures (either total lack of brakes or a really bad feeling / squishy pedal).
• Of those 11 accounts, two people did not disclose the year model of their truck, but
• 100% of the 9 remaining accounts were on 1999 year model 100s.

Re-read the posts, if you will, and see if you agree with my assessment. e9999, in your poll responses, have you been able to discover any total brake failure reports on any other year models?

1999

The Devil's 100

LOL

 

[e9999]

I have not looked at years, but that's an interesting theory. And makes me feel better...!
Let's find out about the other ones then... Folks? Or, David, hit'em with PMs if they posted.
11's only half the total number of failures in the poll, though.

 

[OregonLC]

That would have been the last year before a part number change to ATRAC/VSC so perhaps the re-engineering fixed whatever failure mode was present.

If the years correlate that would be interesting. I'd be more interested, however, in a correlation between failure mode: MC leak, pump fail, line fail, etc.

99 128K miles - no brake failure but my brakes have always been a little soft compared to my other BMW's I drive...

 

[SmoothLC]

So my rig is one of those that experienced a complete failure.

At work yesterday I was going through some of the notes on my desk and noticed one from my conversation with Divinity here in SLC last year.

In the note I wrote, they said they found "water in the actuators". I'll need to go back and check, but I believe the last time I had my brakes worked on was within the previous 18 to 24 mos. prior to the failure.

 

[wngrog]

I am sure it is like the 2000 transmission failures. Once it happens people google it. They find Mud thread and it looks like a bigger more common issue than it is.

 

[Bomar]

I love my 99 and if it fails....it will be replaced and peel out. It is the best vehicle I have ever owned.

 

[gil12]

I wish someone offered a rebuilt item. Why don't they?

(It seems that the piston, accumulator and the motor are all the same part - so I'd be surprised if it was only a 1999 problem.)
