Right now I’m so frustrated I can’t think straight.
I just finished installing a new dual brake master cylinder and booster in my 1965C 10 I/2 ton. I was previously using a 1995 Blazer MC and brake booster. The brakes worked fine but I noticed that after 10 or 15 minutes of driving, the brakes would begin to drag. You could let off of the brake pedal on a slight incline and the truck would not coast backwards.
This new master cylinder and brake booster are doing the EXACT SAME THING. My 63 C10 has the exact same MC and brake booster with front disc and rear drums and I have absolutely no problems there.
I am certain that the brake pushrod is allowing the master cylinder plunger to completely return to the home position.
My next thought is that the pistons in the front disc brake calipers are not moving correctly. If this is true, then they do not pull the brake pads completely off the rotor as they should.
Anyone have thoughts on this matter?
