Disc Brake Pads

REMOVAL AND INSTALLATION

1993-94 323, 626, 929, MX3, MX6, Miata and Protege

CAUTION
Brake pads and shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from brake surfaces! When cleaning brakes, use commercially available brake cleaning fluids.

  1. Disconnect the negative battery cable.
  2. Remove some of the brake fluid from the master cylinder reservoir. The reservoir should be no more than 1⁄2 full. When the pistons are depressed into the calipers, excess fluid will flow up into the reservoir.
  3. Raise the vehicle and support safely.
  4. Remove the appropriate tire and wheel assemblies.
  5. If equipped with 1 lower caliper mounting bolt, remove the caliper lower mounting bolt and pivot the caliper up and support it. If equipped with 2 caliper mounting bolts, remove both and support the caliper with mechanics wire. Do not kink the brake line or allow the caliper to hang by the brake line.
  6. Remove the brake pads, shims and if so equipped, pins. Take note of positioning to aid installation.
  7. If the caliper is single piston design, push the caliper back into the bore with a C-clamp or other suitable tool. If the caliper is a 4 piston type caliper, use Mazda tool 49-0221-600C or equivalent and the old inner brake pad, push the caliper piston(s) into the caliper bore.

    To install:

  8. Install the brake pads and shims to the caliper support. Install the caliper over the brake pads.

    NOTE: Be careful that the piston boot does not become caught when lowering the caliper onto the support. Do not twist the brake hose during caliper installation.

  9. Install the caliper mounting bolt(s).
  10. Install the tire and wheel assemblies. Connect the negative battery cable.
  11. Lower the vehicle and test the brakes for proper operation.

  8. Install the brake pads, shims and spring clips to the caliper support. Pivot the caliper over the brake pads.

    NOTE: Be careful that the piston boot does not become caught when pivoting the caliper onto the support. Do not twist the brake hose during caliper installation.

  9. Lubricate and install the top caliper mounting bolt. Tighten the bolt to 12-17 ft. lbs. (16-23 Nm). Attach the parking brake cable to the operating lever and tighten the locknut to 12-17 ft. lbs. (16-23 Nm).
  10. Start the engine and forcefully depress the brake pedal 5-6 times. Apply the parking brake and make sure the adjustment is within specifications. Adjust the parking brake cable, as required.
  11. Check the disc brake drag by applying the brakes several times and then rotating the wheels to check for excessive dragging.
  12. Install the tire and wheel assemblies. Lower the vehicle.
  13. Test the brakes for proper operation.
