My 1972 Skylark originally had drums. But when I found a donor car for everything else it needed I swapped over the disc brakes, master, booster, proportioning valve. Always had too firm a pedal, had to press really hard way in advance to stop. The rotors were way too shiny so I figure they were glazed and so were the pads. In October I replaced: Master Cylinder (with the same AC Delco with the bigger front reservoir than the rear) Brake booster Drivers side hard Front brake line from proportioning valve to frame New steel braided lines from frame Wilwood two-piston calipers Slotted and drilled rotors Redid rear brakes with all hardware, new shoes, drums, cylinders The pedal was still overly firm but after bedding in the brakes the car will stop, quickly if need be. I made sure the pedal Clevis pin is lubed, it’s in the correct hole (I think, now I wonder if I changed the actual pedal/pedal arm… are they the same between drum and disc cars?) The rod from pedal to booster was set correctly and isn’t at an awkward angle. Maybe it just needs a new proportioning valve? Also maybe the front brake hard line has too many bends in it, at too small a radius and that’s restricting flow? But that would probably make one front brake work better than the other and induce a pull or one wheel locking up? I’m used to it and feel confident it’ll stop, but my wife and son aren’t and neither is a friend I let drive it that’s also a car guy. Compared to all our other cars past and present the pedal is probably twice as firm. That’s why when I drive one of the other cars the first time I brake I end up stopping short. Any ideas?
