Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts on the wheel slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Socket set, ratchet, torque wrench, brake cleaner.
Sub-steps:
1. Inspect the brake pads. If they are below 3mm of thickness, replace them.
2. Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
3. Inspect the rotor for scoring or warping. If damaged, replace the rotor.
4. If the pads are worn, use a brake cleaner to clean the caliper and rotor area.
5. Install new brake pads (if necessary) and reposition the caliper, securing it with bolts.
6. Torque caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs, but check specific vehicle specs).

4. Reassemble

Tools Required: Torque wrench, lug wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

5. Final Checks

Tools Required: None.
Sub-steps:
1. Pump the brake pedal a few times to ensure brake pads are seated correctly.
2. Check the brake fluid level and top up if necessary.
