Solution

1. Preparation

Gather necessary tools and parts, ensuring a clean work area.
Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, and a torque wrench.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground.
Use a jack to lift the vehicle 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.
- Carefully lift the caliper away from the rotor without disconnecting the brake line.
- Inspect brake pads for wear; replace if less than 3mm thickness remains.
Brake Rotors:
- Check for scoring or warping using a straight edge.
- If damaged, replace the rotors.
- If within specifications, clean the rotors with brake cleaner to remove any debris or dust.

4. Replace Brake Pads and/or Rotors (if necessary)

If required, remove old brake pads and install new ones:
- Compress the caliper piston using a brake tool.
- Install new brake pads ensuring they are seated correctly.
If replacing rotors, remove the old rotor and install the new one, ensuring to torque the rotor bolts to manufacturer specifications.

5. Reassemble Components

Reattach the caliper over the new pads or rotor.
Tighten caliper bolts to the specified torque values (typically 80-100 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically 75-80 ft-lbs).
Ensure all tools are removed from the work area.
