Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the wheel is on the ground.
2. Lift the vehicle with a jack 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
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Gently slide the caliper off the rotor; support it to avoid stressing the brake line.
3. Inspect the brake pads for wear. If they are worn to the minimum thickness, replace them.
4. If replacing, remove the old pads and install new pads, ensuring they are seated properly.
5. Reinstall the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake cleaner, socket set, torque wrench
Sub-steps:
1. Check the rotor surface for scoring or excessive wear.
2. If replacement is needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Install new rotors, ensuring they are clean and free of grease.
4. Torque the rotor retaining screws to manufacturer specifications.

5. Final Assembly

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle back to the ground and torque the lug nuts in a star pattern to the manufacturer's specifications.
