To change brake parts 1990-94 323, 626, MX3, MX6, and Protege, loosen the lower guide pin and detach it out of the caliper and the caliper can be pushed upwards to reach the pads, which can be removed out of the caliper mounting support. Check the guide plates and change in case of damage and then position the caliper piston in its bore. Take out a part of the brake fluid in the master cylinder reservoir and take care that it is not filled up to the full. Raise the vehicle and make sure it is not overfilled. Unscrew the correct tires and wheels assemblies then provided there is only one lower caliper mounting screw, take it off and pivot the caliper up; provided there are two screws take off both screws and hold up the caliper with mechanics wire, without kinking the brake line. You need to remove the brake pads, shims and pins and take note of the positioning. In single piston type you can push the piston back into the bore with a C-clamp, in the four-piston types you can use the Mazda tool and the old inner brake pad. Installation Installing the brake pads and shims requires placing them on the caliper support, taking note not to have the piston boot caught, and then attaching the caliper to the pads with the mounting bolts. Install the tire and wheel assemblies, bring the vehicle down and test the brakes. To do the rear, repeat the same, such as getting the
Parking Brake Cable off and reconnecting it where needed with the right amount of torque being applied throughout the process of re-attaching. In the case of the 1995-98 Protege, the steps are related except that the spring and pad pins are deliberately removed and in the process of running the step, care must be taken to make sure that the caliper piston is forced into the bore. The procedures of the 1995 MX3 and the 1995-98 626 and MX6 differ only slightly, having different tools and torque requirements at each stage. Millenia The process of the 1995-98 vehicle involves raising the vehicle, removing the wheels, and working with the caliper lock pin and the V- springs. The procedure of checking the wear indicators and the measurement of the thickness of the lining of the brake pads are checked with specific limits of different models and the replacement of the pads is done in pairs on both sides of the car to achieve balance in the operation and performance.
