Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

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

3. Inspect Brake Components

Tools Required: Torque wrench, caliper tool (if needed)
Sub-steps:
1. Visually inspect the brake pads for uneven wear; replace if the material is worn down to 1/8 inch or less.
2. Check brake rotors for grooves or warping; replace if damaged.
3. Inspect the brake caliper for any sticking or leakage; ensure it moves freely.

4. Replace Brake Pads and/or Rotors

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper bolts and carefully detach the caliper from the rotor. Support it with a bungee cord or similar to avoid straining the brake line.
2. Remove the old brake pads and replace them with new ones, ensuring they are seated correctly.
3. If replacing rotors, remove the old rotor and install the new rotor, securing it with the appropriate torque specifications (usually around 80-100 ft-lbs, depending on the vehicle).

5. Reassemble and Test

Tools Required: Lug wrench
Sub-steps:
1. Reattach the brake caliper and torque bolts to manufacturer specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the specified value (usually 90-100 ft-lbs).
4. Pump the brake pedal a few times to ensure proper brake pad seating.
