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 negative battery terminal to ensure safety.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts on the wheel slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and securely place it on jack stands.
3. Fully remove the lug nuts and take off the wheel to access the brakes.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, torque wrench.
Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts.
2. Carefully slide the caliper off the rotor and support it with a wire hanger (do not let it hang by the brake line).
3. Inspect the brake pads for thickness; replace if less than 3mm.
4. If replacement is needed, remove the old pads and install new ones, ensuring they are properly seated.
5. Reinstall the caliper over the new pads and torque bolts to manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor removal tool, brake cleaner, torque wrench.
Sub-steps:
1. If rotors are scored or warped, remove the rotor by unscrewing the retaining screws.
2. Clean the hub surface with brake cleaner.
3. Install the new rotor, ensuring it is flush against the hub.
4. Torque the retaining screws to the specified value.

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 torque the lug nuts to manufacturer's specifications.
3. Reconnect the negative battery terminal.
4. Start the vehicle and pump the brakes a few times to ensure proper brake pad seating.
