Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel using a socket wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid strain on the brake line.
3. Inspect the brake pads for wear; if they are below the minimum thickness, replace them.
4. If replacing, remove the old brake pads and install new pads, ensuring they are properly aligned.
5. Reinstall the caliper and torque the bolts to manufacturer specifications.

4. Inspect Brake Rotors

Sub-steps:
1. Check the rotor surface for grooves or scoring.
2. If damage is present, consider resurfacing or replacing the rotors.
3. Clean the rotor surface with brake cleaner to remove any debris or contaminants.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer’s torque specification.
3. Pump the brake pedal a few times to seat the pads and calipers before driving.
