To service the rear brakes, begin by loosening wheel lug nuts, raising the vehicle's back up and securing it with jack stands while making sure the front wheels are also blocked for safety purposes. Remove the rear wheels and disengage the parking brake. Make sure that calipers are supported by wire or coat hangers to avoid straining on brake hoses as you remove the discs from their positions. If taking out discs gets difficult due to too much wear from parking brake shoes, simply use a brake adjuster tool or screwdriver through its access hole to retract them. Clean well all of these park brake assemblies using a brake system cleaner except compressed air should be avoided. Disc brakes as well as parking brake drums need to be examined for wear, scoring or out-of-roundness which can be resurfaced at an automotive machine shop if necessary. Re-surfacing drums is recommended by professionals during a brake job in order to eliminate out-of-round issues. However, they cannot go beyond maximum allowable diameter since new ones will have to be replaced otherwise. If no re-surface is intended, sandpaper or emery cloth can remove glazing from the drum surface in a swirling manner. Similarly check if discs are worn out completely. For changing parking break shoes however you should employ hold-down spring tool (or screwdriver), disconnect hold-down cups and springs, unhook secondary shoe return spring, take out strut and strut spring together with lower return spring then detach parking break cable from lever; clean backing plate; lubricate the contact areas between high-temperature grease transfer lever over onto new secondary shoe; install hold-down pin, spring and cup followed by locking down of this spring; proceed installing strut as well as strut spring hooking lower return springs onto each shoe putting adjuster between them placing primary shoe alongside guide plate installing hold-down pin, spring and retainer hooking upper return springs into each shoe; repeat such actions accordingly with another parking break assembly. Thereafter, install
Brake Discs and adjust park breaks shoes by turning the adjuster until they rub on drums then back off the adjuster. Finally, reinstall caliper support brackets, brake pads and calipers as well as rear wheels and lug nuts. Lower a vehicle down, tighten up lug nuts and adjust parking brakes; make sure to check brakes operation before driving in traffic.
