Uneven Wear, Edges or Ends

Problem

Always check where the lining is worn before you take it off the axle.

End wear indicates a drum with ball mouth condition or worn bushings

Indicates bent spider.

Solution

Check drum diameter for ball mouth condition and turn drums or replace. Replace cam bushings at every reline.

If shoe ends or lining must be ground to allow shoes to fit, or for the drum to go on, you may have a bent spider or the wrong shoes.
