Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety glasses and gloves.
Disconnect the battery to prevent electrical shorts.

2. Remove Wheel

Tools Required: Socket set, impact wrench (optional)
Sub-steps:
1. Loosen the lug nuts on the wheel slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader or C-clamp
Sub-steps:
1. Remove the caliper bolts with a socket or wrench.
2. Carefully slide the caliper off the rotor and support it (do not hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Compare new pads with the old ones for proper fit and thickness.
5. Apply brake grease to the backing of the new pads.
6. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Tools Required: Torque wrench, rotor puller (if necessary)
Sub-steps:
1. If rotors are damaged, remove them by unscrewing the retaining screws (if equipped).
2. Clean the hub surface where the rotor mounts.
3. Install new rotors, ensuring they are seated correctly.
4. Torque the rotor screws to the manufacturer’s specifications.

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the caliper over the new brake pads and rotor.
2. Tighten caliper bolts to the specified torque settings.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

6. Final Checks

Tools Required: Brake cleaner
Sub-steps:
1. Clean any grease or debris from the rotor surface with brake cleaner.
2. Reconnect the battery.
3. Test the brake pedal to ensure proper engagement before test driving.
