Re: 1978 corvette brake problem
For a while I've had a problem with my brakes in my 1978 corvette. The red brake light comes on. I can pump the pedal a few times and it goes out but will come on again. The brake pedal is low. Fluid in resevouir is full. I found the drivers front caliper leaking replaced it, bled the sytem and same problem. The car is driven rarely if that makes any difference. TIA Pete
OKTUNES is right, you have too much rotor runout on the wheel where you are finding the air in the caliper. The cheap fix involves a dial indicator and some shim stock between the axle flange and the rotor. Sometimes the rotor can be reindexed and not need the shim stock, so try it on all 5 different wheel studs first.
