I just finished installing a scare bird kit on my 64 barracuda. front disc kit and rear are the stock 9” drums. Bought a MC, prop valve and booster from right stuff. Fits great behind my Crager SST rims. 14x6. I have 1 issue. The brake pedal will not return. I need to use my foot to bring it back up.
Any ideas on what might be causing this issue?
Thanks
