Brake drum backplate wear
A hard brake pedal on my spitfire 1500 led me to find my rear brakes were binding. Decided to service brakes and change hoses. When stripped down I could see wear on the backplate where the handbrake lever has worn at the pivot. Is this normal? I have looked at a few used backplate a on line and they have similar but not so visible wear. Would this effect the wheel cylinder sliding?
There's a corresponding slot in the rear brake cylinder for the lever. This points to the lever moving along with the cylinder, and is therefore not static; in which case the backplate should be flat and smooth with no groove. This means those two backplates of mine are now scrap, or in need of reprofiling...
