Lubricating the Meritor Roller Pin
Warning: Remove all grease or oil from the camshaft head, rollers and brake linings. Always replace linings contaminated with grease or oil, which can increase stopping distances, causing component damage and serious personal injury.
For Q and P series Meritor brakes, lube the cam anchor and cam roller pins when the brake is disassembled, or every six months, with Meritor specification grease 0-617-A or 0-617-B. See Fig. for roller and anchor pin lubrication points.
