My brake holds on small hills, but not as well as I would like. My 67 and
74 Vettes held ok facing up a hill, but not down. I took it in to Chevy and they said the brakes had to be disassembled and it could be Parking Brake shoes - possibly a rotor. They estimated $1,000 - I plan to leave it as is unless ...I normally change disk pads, but are their additional pads that require removal of the rotor? Anyone tried this? Does the Shop Manual cover it.
