Have a problem, seems like the front brakes are locked on the 85 camaro i have. This is what ive done already

Calipers + pads
Master Cylinder

bleed brakes.

Seems to happen when i put the vaccuum on the brake booster, also the pedal is hard.

Any help would be greatly appreciated.

Thanks John

85 Z-28 (work in progress )

 

Even though this isn't the place for the question, replace the rubber brake lines.

I've been explained to me that this is a common problem for alot of mid 80s GM cars.

The rubber brake lines swell over time. The pressure from the master cyl is enough to overcome the restriction but, the bleed off pressure isn't (similar to a one way valve). Once you build up enough pressure the brake will lock and after a period of sitting (usually many hours) the brake will be fine but, after a short peroid of driving, it will lock again.

This was the case in the camaro I bought & the guys Gm truck I work with problem.
