1970 GMC. half ton. Drum brakes
I have replaced the master cylinder and all 4 wheel cylinders and the front brake shoes. The back ones look good. My pedal is still spongy I have bleed the hell out of the lines. Heres the odd thing though if I set the parking brake and step on the brake pedal, the pedal is stiff like its suppose to be.
Any ideas what might be wrong?????? Im going to pull the back wheels off and make sure the back drums are adjusted and tight like they are suppose to be. What else can I do? This just became my daily driver so I need to get fixed tonight.
