In my effort to find the cause of a sticking front wheel on my '76 R90S I got as far as inserting the 8 mm x 1.25 x 50 mm bolt into the bearing pin. I assume the bearing pin must be removed. Showing my loss of mental capability, I am unsure how to proceed. Does the bearing pin need to be removed from the caliper to release it from the disc? The master cylinder and the surrounding are clean and dry. The calipers show no sign of brake fluid leakage. The front wheel can be turned by hand but there is much more resistance than I would expect.
Recommendations will be appreciated.
