Remove Mazda MPV Drum Brakes
Introduced in 1989 as a rear-wheel drive minivan, the Mazda MPV featured front disc brakes and rear drum brakes. By 1999, the minivan was available in four-wheel and front-wheel drive and featured rear disc or rear drum brakes. While removing the rear drum brakes is much easier than replacing them, the front disc brakes will require more frequent servicing. This is because the front disc brakes provide 75 percent braking capacity for the Mazda MPV.
Instructions
1. Loosen the wheel nuts of the rear tires with the lug wrench by turning them counterclockwise 1/4 turn.
2. Raise the rear of the Mazda MPV and safely support it on jack stands.
3. Remove the wheel nuts and then remove the wheels.
4. Use the impact screwdriver and a hammer to remove the drum retaining screw. Remove the drum. If the drum is stuck to the hub, give it a sharp strike on the flat base of the drum to shock it free.
5. Pull back on the adjusting cable to disengage the adjusting lever from the adjusting screw. Move the outboard side of the adjusting screw up and then back off the pivot nut.
6. Pull the adjusting lever, cable and adjuster spring down toward the rear to unhook the pivot hook from the hole in the secondary shoe plate.
7. Remove the adjuster spring and lever. Use a pair of needle nose pliers to help if necessary.
8. Remove the secondary shoe retaining spring using the needle nose pliers. Remove the primary shoe retaining spring in the same fashion and then unhook the cable anchor. Remove the anchor pin plate if applicable.
9. Remove the guide of the parking brake cable from the secondary shoe.
10. Use the brake hold-down spring tool while pressing on the hold-down pin with a finger. Turn the tool to align the notch in the spring cup to the slotted end of the pin. Remove the spring assembly, the brake shoe and then pull the hold-down pin out from the back of the backing plate. Repeat this step for the other shoe.
11. Remove the adjusting screw, pivot nut and socket.
12. Remove the parking brake link and spring using the pliers. Disconnect the parking brake cable from the parking brake lever.
13. Remove the retaining clip and spring washer from the secondary shoe. Use the slotted screwdriver to spread the clip apart and then remove the parking brake lever from the shoe plate.
Tips Warnings
When replacing the rear shoes, it is recommended to remove one side at a time while leaving the other side intact. This way you can use the assembled side as a reference for replacing the shoes and springs.
Always replace the springs and hardware kit when replacing rear shoes. Due to rust, corrosion and constant tension on the springs, a new set will properly hold the replacement shoes in place.
