Rear PBR brakes
I have the 9 bolt rear with the 1LE/PBR disk brakes. The stock front brakes work ok but I'll be upgrading to LS1 brakes over the Winter.
My issue is about the rear brakes failing. I had the car up on jack stands and at an idle with the wheels in the air I cant stop the rear tires from spinning. I can stand on the pedal and the tires keep going..... any ideas???
**had no luck after bleeding the rears

Re: Rear PBR brakes
its both sides, I'm thinking that proportioning valve upgrade sparing will be a good place to start trouble shooting..thanks
