Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, microfiber cloth.
Ensure the car is parked on a level surface and the ignition is off.
Safety Warnings: Disconnect the battery before working on the braking system to prevent accidental activation.

2. Remove the Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
Lift the vehicle with a jack and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
2. If the pads are worn down to the indicator or are below the minimum thickness, replace them.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are secured properly in the caliper bracket.
5. Apply brake grease to the back of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for scoring or damage; replace if necessary.
2. If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install the new rotor, ensuring it is aligned correctly and secured.
4. Clean the new rotor surface with brake cleaner to remove any protective coating.

5. Reassemble the Brake Components

Sub-steps:
1. Reattach the caliper over the new pads, ensuring it fits snugly against the rotor.
2. Tighten the caliper bolts to the manufacturer's specified torque settings.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque.
