2002 Jeep Liberty Replace Brakes & Rotors
Applying a vehicle's brakes creates friction and heat that wears down brake pad material over time; once the material is sufficiently worn, the pads must be replaced. Instead of replacing the rotors however, you have the option of having them machined. This is where a thin layer of the worn, pitted or uneven metal is removed from the surface of the rotor, allowing it to be reused. If your 2002 Jeep Liberty's brakes are spongy, noisy or feel uneven, it's probably time to change the brake pads and rotors.

 Replace Brakes & Rotors
- Loosen the lug nuts on the wheel with a tire iron just enough so they can be turned by hand--do not remove them at this stage. Raise the car and place it on jack stands. Remove the lug nuts and the wheel.
- Remove the caliper mounting bolts with a socket wrench; one at the top and one at the bottom of the caliper. Detach the caliper and rest it above the rotor. Remove the bolts from the caliper mounting bracket with a socket wrench. Lift the caliper mounting bracket up and off the rotor and brake assembly.
- Remove the rotor; pull it off the hub and over the lug bolts. Clean the new (or machined) rotor with brake parts cleaner. Replace the new rotor onto the lug bolts and push it back onto the hub. Replace the caliper mounting bracket over the rotor and onto the brake assembly. Secure the bolts with a socket wrench.
- Insert one of the old brake pads into the caliper against the caliper piston. Position a C-clamp around the caliper and onto the brake pad. Retract the piston into the caliper by slowly turning the screw clockwise. When the caliper piston is fully retracted, unscrew and remove the C-clamp and old brake pad.
- Apply anti-seize compound to the back of the new brake pads and install them into the caliper. Replace the caliper into the mounting bracket; then insert and tighten the caliper mounting bolts with a socket wrench.
- Apply anti-seize compound to the lug bolts. Replace the wheel and tighten the lug nuts. With the engine running, pump the brakes to restore pressure to the lines before driving.
 Tips & Warnings
- If they are rusted in place, tap the caliper or rotor with a rubber mallet to loosen.
- Never replace only one brake; you must replace both front or both rear brakes at the same time.
- Brake dust is hazardous, do not breathe it in.
- Wipe off any anti-seize compound on the surface of the new pad or the rotor with a paper towel.
