They looked great last year. The glue looked fine. The glue and brakes are 30 years old.
Someone else here already said it. Did I listen? NO! Do I know Better? Yes! Did I learn the hard way? Yes.
Ordering brakes tonight.
Word to the wise...When restoring old motorcycles, REPLACE THE BRAKE SHOES!
Lucky I handled the sudden deceleration o.k. as a wild ride from 30MPH to 0 MPH with the rear wheel locked up.
So, lesson learned the medium hard way.
