More on Plymouth brakes

Question & Answer:

I’m writing to answer the question from Charlene (September 2007) who asked why the front brake drum wouldn’t go back onto her 1947 Plymouth.

These cars had excellent brakes but there are two basic adjustments to center the shoe on the backing plate. Number one is the anchor pin adjustment and number two is the cam adjustment. Both adjustments must be made in order to center the shoes. In some instances the cam adjustment can’t be made because the cam fails to move as it has slipped on the bolt adjustment stud and must be welded to allow this adjustment.
