Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and gloves.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Use a jack to lift the vehicle and secure 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 thickness of the brake pads. If they are less than 3mm thick, they should be replaced.
Remove Brake Caliper:
- Use a socket set to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar, avoiding strain on the brake line.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket (ensure they align correctly).

4. Inspect and Replace Brake Rotors

Remove Brake Rotor:
- If the rotors are worn or scored, remove the caliper bracket by unscrewing the bolts.
- Slide the rotor off the hub. If it is stuck, gently tap it with a mallet.
Install New Brake Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub.

5. Reassemble Brake Components

Reinstall the caliper bracket over the new rotor and torque the bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (usually about 30-40 ft-lbs).

6. Reinstall Wheel and Final Checks

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts in a star pattern to ensure even pressure.
Pump the brake pedal several times to ensure proper caliper function and pad seating.
