While checking my wheel bearings and inspecting the brakes yesterday I found an unusual situation. On one brake assembly the magnet had somehow jumped over the adjustment wheel and got lodged between the adjustment wheel and the back brake assembly plate. This prevented the brake activation arm from moving. In addition, the brake shoe pads were worn all the way down to bare metal.
The brake drum was pretty badly abrased both in the area where the shoes make contact, and also where the magnet makes contact. I have never seen this before. Maybe I just missed it on my last brake inspection, and I can't imagine what events led to this.
While not relating to this failure, I was wondering if any lubrication should be sparingly added to the moving parts of the brake assembly, i.e. the arm with the magnet that swings to move the shoes into a braking position? Obviously you would not want to over-lubicate and get oil on the brake shoes.
Any advice appreciated.
