How to Replace Front Rotors on a 1990 Mazda

It is not difficult to replace the front rotors on a 1990 Mazda if you have the proper tools. The brake rotors work along with the brake pads to stop your car when you push on the brake pedal. The master cylinder pushes brake fluid through the brake lines. This brake fluid then flows into the brake calipers, which push a piston out of the brake caliper. The pads squeeze the rotor between them to slow and stop the Mazda.

Instructions

1

Park the vehicle on a level surface and turn off its ignition. Place a set of wheel chocks behind the rear wheels. Loosen the tire's lug nuts with the lug wrench. Raise the front end of the Mazda up with the automobile jack. Place a jack stand under the vehicle and raise it to the frame.

2

Remove the lug nuts using the lug wrench. Pull the wheel off the car. Remove the brake caliper with a socket and ratchet and secure it to the strut using a wire tie. Do not allow the caliper to hang loose or you may stretch and damage the brake line.

3

Remove the two retaining screws from the face of the rotor using the screwdriver, turning counterclockwise. Pull the rotor off the wheel assembly.

4

Put the new rotor on the wheel assembly. Install the two retaining screws, turning them clockwise with the screwdriver. Place the brake caliper into the mounting bracket and tighten the bolts with the socket and ratchet. Put the wheel on the car and tighten the lug nuts with the lug wrench.

5

Place the jack under the vehicle and remove the jack stand from under the Mazda. Lower the car to the ground with the jack. Repeat the process on the other wheel.
