Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on the electrical components.

2. Inspect and Replace Brake Rotors

Remove the Wheel
- Loosen lug nuts with a socket set.
- Jack up the vehicle and secure it on jack stands.
- Remove the wheel.
Assess the Brake Rotor
- Use a dial indicator to check for warping.
- If warping exceeds manufacturer specifications (typically 0.002 inches), proceed to replace the rotor.
Remove the Old Rotor
- Remove the caliper by unbolting it (usually requires a socket wrench).
- Secure the caliper to avoid strain on the brake line.
- Remove any retaining screws or clips from the rotor and slide it off.
Install the New Rotor
- Clean the hub surface to ensure proper contact.
- Place the new rotor onto the hub and secure with screws or clips as needed.

3. Replace Brake Pads

Remove Old Brake Pads
- Remove the caliper bracket if necessary.
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads
- Apply brake grease to the backing of the new brake pads (avoid the friction surface).
- Install the new brake pads into the caliper bracket.
Reattach the Caliper
- Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).

4. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

5. Final Checks

Reconnect the battery (if disconnected).
Pump the brake pedal to seat the pads against the rotor.
Check brake fluid levels and top off if necessary.
