Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather necessary personal protective equipment (gloves, eye protection).

2. Remove Wheel

Using a socket set, loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack, then safely support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the brake pads for wear indicators. If they are below the minimum thickness (usually around 3mm), proceed to replace.
Remove Old Brake Pads:
- Locate the caliper mounting bolts and remove them using a socket wrench.
- Slide the caliper off the rotor carefully and support it using a bungee cord or similar device to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads (if applicable).
- Install the new brake pads into the caliper bracket.
Reassemble Caliper:
- Position the caliper back over the new pads and secure it with the caliper mounting bolts. Torque bolts to the manufacturer's specifications (usually around 25-30 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: If the rotors are scored or uneven, remove them for replacement.
Remove Old Rotor:
- Locate any retaining screws and remove them if present.
- If rotors are stuck, gently tap them with a rubber mallet to free them from the hub.
Install New Rotor:
- Position the new rotor onto the hub and secure it with retaining screws if applicable.

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications (usually around 80-100 lb-ft).
Repeat the above steps for the other side if necessary.
