Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Tools Required: Socket set
Sub-steps:
1. Loosen lug nuts 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 completely and take off the wheel.

3. Inspect and Remove Brake Components

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper mounting bolts using a socket.
2. Carefully slide the caliper off the brake rotor; support it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. If necessary, remove the caliper bracket by unscrewing its bolts.

4. Replace Brake Pads and Rotors

Tools Required: Brake pad spreader or C-clamp, torque wrench
Sub-steps:
1. If the rotors are damaged, remove them from the hub by unscrewing the retaining screws or using a hammer to break them loose.
2. Install new brake rotors onto the hub, ensuring they are seated correctly.
3. Place new brake pads into the caliper bracket.
4. Compress the caliper piston using a brake pad spreader or C-clamp to allow for the new pads' thickness.
5. Reinstall the caliper over the new pads and secure it with the caliper mounting bolts.
6. Torque the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications.
3. Pump the brake pedal a few times to ensure proper brake pad seating.
4. Check brake fluid levels and add fluid if necessary.
