Drum Brake System Basics - Night School

Rear brake assembly with parking brake lever and cable is busier than the front brake layout. Brake shoes with modern, non-asbestos lining have been cam-arc surfaced. This matches the radius of the shoes to the resurfaced brake drum's contour. Cam-arc was virtually banned from the '80s- through the '90s due to asbestos dust hazards. Availability of non-asbestos lining has revived interest in this brake "tuning" procedure. The process provides quicker seating of the lining and better brake response after a brake job.
