Recommended Practice
Transit Bus Front and Rear Axle S-Cam Brake Reline
Abstract
This recommended practice provides guidelines for performing a complete brake reline on the front and rear axle of a bus with S-cam brakes. The practice includes the disassembly, cleaning, inspection and assembly. This recommended practice is to be used in conjunction with the manufacturer’s service manual.
It is recommended that all components be replaced equally on both wheel ends of the axle. Failure to do so may affect braking performance.
