Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Place wheel chocks behind the rear wheels to prevent movement.
3. Wear safety goggles for eye protection.

2. Remove the Wheel

Tools Required: Lug wrench, jack, jack stands.
Steps:
1. Loosen the lug nuts slightly while the wheel is still 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 to access the brake assembly.

3. Inspect Brake Components

Tools Required: None.
Steps:
1. Visually inspect the brake pads for wear; they should be at least 3mm thick.
2. Check the brake rotors for grooves or scoring; they should be smooth.
3. Confirm that the brake calipers are functioning correctly and not seized.
4. Inspect the brake lines for leaks or damage.

4. Replace Brake Pads and Rotors (if necessary)

Tools Required: Socket set, torque wrench, brake cleaner.
Steps:
1. If pads are worn, remove the caliper bolts, and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Replace with new brake pads, ensuring they are properly seated.
4. If rotors are damaged, remove the rotor from the hub and install a new rotor.
5. Clean the new rotor with brake cleaner to remove any protective coating.
6. Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and torque the lug nuts to the specified torque value.
3. Pump the brake pedal to ensure proper brake pad seating and check for any abnormal noises.
