Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Lift the vehicle with a jack and securely place jack stands underneath.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Examine brake pads for wear. If they are less than 3mm thick or show uneven wear, they should be replaced.
Remove:
- Remove the caliper bolts using a socket set (typically 12mm or 14mm).
- Lift the caliper off the rotor and secure it using a bungee cord or rope (do not let it hang by the brake line).
Replace:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are positioned correctly.
- Apply brake grease to the backs of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check the rotors for deep grooves or excessive wear. If damaged, they should be replaced.
Remove:
- Remove the caliper bracket by unscrewing the bolts.
- Slide the rotor off the hub.
Replace:
- Install the new rotor, ensuring it is seated properly against the hub.
- Reinstall the caliper bracket and torque the bolts to manufacturer specifications (typically 70-80 ft-lbs).

5. Reassemble and Check

Reinstall the brake caliper and torque bolts to manufacturer specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically 80-100 ft-lbs).
Repeat the procedure for the opposite side if necessary.
