Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery cable to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and support with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket wrench and carefully slide the caliper off.
- Check the thickness of the brake pads; replace if less than 3mm.
Replacement:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation.
- Apply brake grease to the back of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for signs of wear or damage. If scored or warped, replace them.
To replace, remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
Install the new rotor and secure with screws.

5. Reassemble Components

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts in a star pattern to the manufacturer’s specifications (usually around 76 ft-lbs).

6. Final Checks

Reconnect the negative battery cable.
Pump the brake pedal several times to ensure proper engagement of the brake pads.
