Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheels

Loosen lug nuts slightly before lifting the vehicle.
Use a hydraulic jack to raise the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheels.

3. Inspect and Replace Rotors

Inspection: Check each rotor for warping using a dial indicator. If warped beyond specifications (usually over 0.005 inches), proceed to replace.
Removal: Unbolt the brake caliper and hang it using a bungee cord (do not let it dangle from the brake line). Remove the rotor by unscrewing any retaining screws if present.
Replacement: Install new rotors, ensuring they are properly seated. Torque the retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for any corrosion.
Apply brake grease to the backing of new pads and install them into the caliper bracket.
Reinstall the caliper over the new pads and torque the caliper bolts to specification.

5. Reassemble Wheels

Place the wheels back on the hubs and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specifications.
