Brake Failure & Wreck in E36 M3 at VIR

[D_Eclipse9916]

DJ - Have you heard any discussion on ways to prevent this from happening? Sounds like an annual cleaning of the wheel speed sensors might be a good thing to add to the off-season checklist. What else could cause this?

To be honest, this is very rare. And there have been discussions all around because it is simply built into most ABS cars. Everything from Porsche to Camaros have this problem, and nobody really has "solved" the issue. E46 M3s has the option of swpaping in the motorsports ABS ECUs, and report in that they don't have it. But it happens very rarely, so who knows? Even Porsche's venerable 997 GT3 has problems with it, and if Porsche's GT3 ABS has it and hasnt been solved, I doubt the E36s will be at this point.

There are theories, but many beleive cleaning the wheel speed sensors helps, but to fix "ice mode" you have to let off the brakes, and get back into it. (just as you would without ABS). I encounter it braking on the backstraight since I am hard braking over the curbing on the left and pop 1/2 wheels in the air. I momentarily pop completely off the brakes and then back in to settle it if it occurs. (once in a blue moon even driving like that).

I have spun out (I got lucky and didnt hit anything) because of it. Many racers have hit walls because of it. Eric Wong in his m3 hit an HPDE guy, multiple GTS Porsches, and now one of our own :/
