Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Disconnect the battery to ensure safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle at the designated jacking points.
Secure the vehicle on jack stands for safety.

3. Remove Wheels

Use a lug wrench to remove the wheel nuts.
Take off the wheels to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Use a run-out gauge to check for warping. If warped beyond specifications (usually 0.002 inches), replace.
Remove Rotors: Unscrew the caliper bracket bolts and remove the brake caliper. Support the caliper with a bungee cord, do not let it hang by the brake line.
Replace Rotors: If necessary, remove the rotor retaining screws and slide off the rotor. Install the new rotor, securing it with screws.

5. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads; if they are below recommended thickness (usually 3mm or less), replace them.
Remove Pads: Slide out the old pads from the caliper bracket.
Install New Pads: Lubricate the backing of the new pads with anti-squeal grease and install them into the caliper bracket.

6. Reassemble Braking System

Reinstall the brake caliper over the new pads.
Torque the caliper bracket bolts to the manufacturer's specifications (usually around 80 ft-lbs).
Reattach the wheels and torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).

7. Lower the Vehicle

Remove jack stands and lower the vehicle using the hydraulic jack.
Reconnect the battery.
