Drum Brake System: Service and Repair

WARNING:
- BREATHING ASBESTOS DUST IS HAZARDOUS TO YOUR HEALTH. DUST AND DIRT PRESENT ON BRAKE AND CLUTCH ASSEMBLIES MAY CONTAIN ASBESTOS FIBERS THAT ARE HAZARDOUS TO YOUR HEALTH WHEN MADE AIRBORNE BY CLEANING WITH COMPRESSED AIR OR BY DRY BRUSHING.
- WHEEL BRAKE ASSEMBLIES SHOULD BE CLEANED USING A VACUUM CLEANER RECOMMENDED FOR USE WITH ASBESTOS FIBERS, SUCH AS ROTUNDA ASBESTOS BRAKE DRUM SYSTEM WITH VACUUM 164-R3622, OR EQUIVALENT. DUST AND DIRT FROM THE VACUUM SHOULD BE DISPOSED OF IN A MANNER THAT PREVENTS DUST EXPOSURE, SUCH AS SEALED BAGS. THE BAG MUST BE LABELED ACCORDING TO OSHA INSTRUCTIONS AND THE TRASH HAULER NOTIFIED AS TO THE BAG'S CONTENTS.
- IF A VACUUM SUITABLE FOR ASBESTOS IS NOT AVAILABLE, CLEANING SHOULD BE DONE WET. IF DUST GENERATION IS STILL POSSIBLE, TECHNICIANS SHOULD WEAR GOVERNMENT-APPROVED TOXIC DUST PURIFYING RESPIRATORS.
- GRINDING OR SANDING ON BRAKE LININGS, PADS, ROTORS, DRUMS, OR CLUTCH FACINGS SHOULD BE DONE WHILE USING PROPER EXHAUST-VENTILATED EQUIPMENT. OSHA REQUIRES AREAS WHERE ASBESTOS DUST GENERATION IS POSSIBLE TO BE ISOLATED AND POSTED WITH WARNING SIGNS. ONLY TECHNICIANS CONCERNED WITH PERFORMING BRAKE SERVICE SHOULD BE PRESENT IN THE AREA.

Use denatured alcohol to clean component parts. Allow the parts to completely air dry. Apply Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AB or DOT 3 equivalent meeting Ford specification ESA-M6C25-A to the parts before installation

CAUTION: Do not use denatured alcohol for flushing the system or cleaning assemblies where alcohol could be trapped and subsequently contaminate the brake fluid. Contaminated fluid may cause eventual failure of rubber components in the system.
