I have a 2005 chevy malibu maxx.
The front driver side brake caliper does not retract unless i open the bleeder screw.
if i leave it overnight it will retract until i have to use it a couple times then ill have to
open the bleeder screw. I’ve been told if the piston retracts when i open the bleeder then the caliper
is OK. Anyone have an idea of what i should look for? (It does have ABS) Thanks Tom
It is possible that the flexible brake hose for the left front brake caliper is the culprit. It may be worn out on the inside and acting as a check valve so that the fluid does not flow back to the master cylinder. Opening up the bleeder screw relieves the pressure and allows the piston to retract thus releasing the brake.
I’ll try replacing that line thanks.
