The disc brakes on my ‘63 GT Hawk are binding, and I think it’s high time I centered them over the rotor. I’ve never done it in the 33 years I’ve owned it and I’m sure in that time I’ve screwed it up.
Can someone explain to me how to go about this?
I’ve read the procedure Bob Johnstone wrote about on his resource page at least a dozen times and it just doesn’t make any sense to me.
Per his instructions, with the shims removed and the caliper snugged down, I have .025” space between the rotor and caliper at the front inside and .016” at the rear inside. The outside space is WAY too big to measure with feeler gauges I’ll bet it’s at least 1/8”. He says you’re supposed to add those 2 inside measurements together and then divide that by 2 and then by 2 again and then to insert that measurement of shims to center it. That’s only a .010” shim so it’s not even close.
