Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves throughout the process.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner
Sub-steps:
1. Remove the caliper by loosening the caliper bolts with a socket.
2. Carefully slide the caliper off the brake pads without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and rotor surface with brake cleaner.
5. Install new brake pads, ensuring they are oriented correctly.
6. Reinstall the caliper and torque the bolts to manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if necessary), torque wrench
Sub-steps:
1. If rotors are scored or warped, remove them by unscrewing the retaining screws or using a rotor puller.
2. Install new rotors, ensuring they are clean and free of oil.
3. Torque any retaining screws to the manufacturer's 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 back to the ground and fully tighten the lug nuts in a crisscross pattern.
3. Test the brakes by pressing the pedal several times to seat the pads against the rotors.
