The front disc brakes on the 72 GS I bought are very grabby. I've never done any brake work, is adjusting them very hard or am I looking at a different problem anyhow? I have a 70 chassis manual, were disc brakes the same between the years?
disk brakes are the same . brake pads need to be broken in , not used hard for a few miles . any time i install new brake pads , i sand the surface of the pad to remove any glossiness & also sand a bit of the outside edges . if any brake fluid leaks onto the pad surface , they will grab . also try getting the pads hot . they may just need a breakin period . do your rear brakes work okay ? how is your proportioning valve working ?
