How to Install Brake Rotors in a Montero

Mitsubishi Montero uses front disc brakes to help stop your SUV when you push on the brake pedal. The disc brakes consist of three primary parts: the caliper, the brake pads and the brake rotor. When you replace the rotor, you must replace the brake pads, which wear on the the rotor in a unique pattern. If you replace the rotor without replacing the brake pads, you will compromise the ability of the brakes to stop your Montereo.

Procedure:
1. Park the Montero on level ground. Lift the hood and prop it open. Remove the cap from the brake master cylinder located against the firewall on the driver's side of the Montero.
2. Loosen the lug nuts on the driver's side front tire using the tire iron supplied with the Montero.
3. Place a jack under the frame directly behind the tire. Raise the Montero until you can place a jack stand under the frame. Lower the vehicle onto the jack stand.
4. Remove the lug nuts and pull the wheel off the wheel studs.
5. Remove the two bolts that thread into the backside of the wheel caliper, using a socket and ratchet.
6. Pull the wheel caliper off the rotor and hang it off the coil over-spring using a wire tie.
7. Remove the splined washer from the wheel stud. Only one wheel stud has the washer. Use a screwdriver to pry it off.
8. Pull the rotor off the axle hub and wheel studs. If necessary, hit the back of the rotor with a rubber mallet to get it off the axle hub.
9. Slide the new rotor onto the wheel studs and axle hub. Slide the splined washer onto one of the wheel studs to lock the rotor in place.
10. Place a pair of vice grips over the rear brake pad on the caliper and force the piston closed. This makes room for the thicker brake rotor and brake pads.
11. Remove both brake pads from the caliper and place the new pads into the caliper. The pads do not bolt in place.
12. Slide the brake caliper over the rotor and secure it with the two bolts, using the socket and ratchet.
13. Remount the wheel on the wheel studs and secure it using the lug nuts and the tire iron.
14. Raise the Montero until you can remove the jack stand. Lower the vehicle to the ground. Doublecheck the lug nut tightness with the tire iron.
15. Duplicate the process on the passenger's side brake.
16. Close the cap on the brake master cylinder once you complete the rotor replacement on the passenger's side of the Montero.
