Rear brake grabbing early

Post by Hatchetf15 » Tue Oct 08, 2019 11:21 am

Gents,
My C2 left rear is locking up a little early during threshold braking, just before I start easing up. Stock rotor and warm Akebono pads. PSM off. Straight line or turn either direction. ATE fluid has less than 2000 miles. Any ideas on a fix?
Cheers,
Mike

Time for a caliper rebuild?

Could be, Gnat. They have 90k on them.

Is alignment/camber correct on that corner? If the contact patch is smaller than it should be, the brakes may be overpowering that tire and locking it up.

Is the tread wear pattern the same on both rears?

In neutral on jack stands, does the problem wheel turn as freely as the non-problem side? Any bearing play/grind?

Oversteer: You will hit the wall with the rear end.
Horsepower: How hard you will hit the wall.
Torque: How far you will move the wall.

5chn3ll,
When I get home next week, I’ll put it up and check bearing and caliper...bleed that corner just cuz. Fresh alignment (just -1.8 on the rears), fresh suspension everything and new-ish AS3+ shoes. That side didn’t chirp at all with the 19’s and PS4S.
