Hard brake pedal...

[dave68]

Hi all, I need help from the experts-that's you! I have a 68 LWB C10 that underwent a frame-off resto. The truck came with 11"X2" drums on all 4 corners. During the resto I replaced: lines, hoses, wheel cylinders, master cylinder, shoes and drums with new. The push rod and parking brake cable are adjusted properly and it has been bled repeatedly, with no air or leaks noticed. The auto-adjusters work as advertised. That said, here is the problem: I have to almost stand on the brake pedal to make the truck come to a stop. It does not swerve and stops straight and true when the brakes are applied even during high speed stops. All the shoes appear to be contacting the entire drum surface and are not glazed... I have a theory: The friction material is too hard? -Has anyone else had this problem in the past? I do not want to upgrade to dics or add power assist, as the truck was restored to almost original. Before the resto, the orginal 45 year old brakes stopped the truck with little effort, so it has to be a recent addition causing the problem... Please let me know what you think. -Dave
