  Q: What precautions should be taken when working on the Brake Shoe Set to ensure safety and proper installation on Mazda 626?

  A:

  Whenever working on the brake system, be aware that asbestos dust is present, which is harmful to health, so take care not to inhale it. Raise the vehicle and support it securely on jackstands, then remove the wheel. All four rear shoes should be replaced at the same time, but to avoid mixing up parts, work on only one brake assembly at a time. Remove the drum/hub assembly; if it cannot be removed easily, remove the plug in the backing plate, insert a screwdriver through the hole, and press on the hold spring to widen the shoe clearance. If this doesn't allow drum removal, loosen the parking brake lever adjusting nut to increase the stroke. Remove the brake shoe return springs, hold down springs, and pins, then take out the leading shoe and the adjuster, which may require releasing the adjuster with a screwdriver to ease the removal. Next, remove the trailing shoe and disconnect the parking brake wire, followed by removing the clip and disconnecting the operating lever from the shoe. Lightly lubricate the contact surfaces of the brake backing plate with white lithium base grease, then install the operating lever on the new trailing shoe and the trailing shoe with the anti-rattle spring in place. Connect the parking brake wire, assemble the leading shoe and adjuster, connect the adjuster to the anti-rattle spring, and rotate the assembly into position. Install the hold down springs and return springs, then center the shoe assembly. Inspect the brake drum for cracks, score marks, deep scratches, and hard spots, which will appear as small discolored areas; if hard spots cannot be removed with fine emery cloth or if any other conditions exist, the drum must be taken to an automotive machine shop to be turned. If the drum will not "clean up" before reaching the maximum diameter in the machining operation, it must be replaced with a new one, with the maximum diameter cast into each brake drum. Finally, install the brake drum/hub assembly, adjust the wheel bearings, mount the wheel, install the wheel lugs, tighten to the specified torque, lower the vehicle, and make a number of forward stops to adjust the brakes until satisfactory pedal action is obtained.
