How to Replace a Rear Brake Rotor in a Miata

Brake rotors or brake discs are essential to the proper functioning of the braking system in your car, and thus to your safety. The rotors are cylinder in shape, and their purpose is to provide breaking to your Miata; this occurs as the brake pads connect with the rotors, which causes friction and consequently stops the wheels from turning. With the right equipment, it is possible to replace your Miata rotors at home, which can be cost effective, as you eliminate the labor cost at the mechanic's shop. This task should only take 30 minutes or so to accomplish.

Instructions

1

Switch the Miata into the first gear and activate the parking brake. Find the Miata jack--this should be located in the trunk of your car, near the spare tire. Locate the radiator, near the front of the car. You should then see the designated front jack point, which will be very close to, or an embellishment of, the car frame. Jack up the car, using a pumping motion.

2

Locate the brake caliper. This is a metal piece that is attached to the rotor, and it should look like a clamp. There will be multiple bolts on the top and bottom of the caliper. Using the wrench, unbolt the caliper bolts with the circular or socket end.

3

Locate the spring above the caliper. Using a zip tie, attach the caliper to the spring, so that it doesn't get in the way.

4

Using the rubber mallet, hit the back of the brake rotor. This piece should slide right off with little effort. Slide the new rotor into place on the hub assembly.

5

Cut the zip tie with scissors, and place the caliper back over the rotor. Tighten the brake caliper bolts with the wrench.

6

Gently lower the car, using the jack. Put the car back into "Park," and release the emergency brake.
