The safe handling of asbestos fiber dust during brake drum services becomes essential since breathing in the substance can create health concerns. A specialist vacuum cleaner for asbestos fibers should be used to clean brake and clutch assemblies followed by a proper labeling procedure according to OSHA standards and proper sealing and notification to the trash hauler about the asbestos content. Any cleaning procedure requires an appropriate vacuum which absent requires technicians to wear government-approved toxic dust purifying respirators. Working areas where asbestos dust exists must be isolated with warning signs that protect only the brake or clutch maintenance staff from entry. Even braking performance requires replacing rear
Brake Shoes and linings at both ends of a single axle. Technicians must initiate the process by eliminating wheel along with tire assembly. The use of brake drum pullers or torches should be strictly avoided since they might cause deformation. A rusted brake drum can be removed from its pilot diameter on the
Axle Shaft by tapping it between wheel studs at its center. Remove the spring nut from the component then extract the brake drum off the axle shaft. A losing brake drum requires users to first loosen the brake shoe adjusting screw nut then move the brake shoe adjusting lever away from the adjuster screw with a screwdriver before using the Brake Adjustment Tool to regulate the screw nut. The Brake Drum Micrometer should be used to check the inside diameter of the brake drum for replacement when the maximum diameter surpasses the stamped specifications. Installation of the rear brakes requires shoe adjustment and you should revert to the removal sequence.
