Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen and remove wheel lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Inspect brake pads for wear; replace if unevenly worn.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation.
- Lubricate the backing of the pads with brake grease to reduce noise.

4. Check and Replace Brake Rotors (if necessary)

Inspection:
- Inspect rotors for wear; look for signs of warping or deep grooves.
Replacement:
- If rotors are worn beyond specifications, remove the rotor by unscrewing the retaining screws.
- Install new rotors, ensuring they are properly torqued to the manufacturer’s specifications.

5. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.

6. Fill and Bleed Brake System (if necessary)

Check brake fluid level and fill to the appropriate level if low.
If calipers were disconnected, bleed the brake system using a brake bleeder kit to remove air.

7. Final Checks

Reconnect the battery.
Test the brake pedal for firmness before driving.
