Installation





CLEANING AND INSPECTION
Clean metal portion of brake shoes. Check to see if shoes are bent. Lining should show contact across entire width and from heel to toe, otherwise replace. Shoes with lack of contact at toe or heel may be improperly ground. Clean and inspect support and adjusting screws. Apply a thin coat of Mopar Multi-Purpose Lubricant or equivalent to the threads of the self adjuster. Replace adjusting screw if corroded. If old springs have overheated or are damaged, replace. Overheating indications are paint discoloration or distorted end coils.
