Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Inspect the brake pads for wear; replace if the friction material is less than 3mm.
Brake Rotors:
- Check for scoring, warping, or excessive rust on the rotors.
- If damaged, proceed to replace the rotors.

4. Replace Brake Pads and Rotors (if necessary)

If replacing brake pads:
- Remove the old pads and install new pads, ensuring they are properly seated in the caliper bracket.
If replacing rotors:
- Remove the old rotor from the hub.
- Install the new rotor and ensure it is properly aligned.

5. Reassemble and Test

Reattach the caliper over the new pads or rotor and tighten the caliper bolts to manufacturer specifications (typically between 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts, then lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 75-85 ft-lbs).
Reconnect the battery.
