Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Brake cleaner
- C-clamp (or brake caliper tool)
- Jack and jack stands
Lift the vehicle and securely support it with jack stands.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Remove the lug nuts and wheel to access the brake components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket.
- Carefully lift the caliper off the rotor and support it using a bungee cord or similar tool.
- Inspect the brake pads for thickness. Replace if they are below the manufacturer's minimum specification (usually around 3mm).
Rotors:
- Check the rotor surface for grooves or scoring. If damaged, they may need to be resurfaced or replaced.
- Measure rotor thickness with a micrometer; ensure it meets specifications.

4. Replace Brake Pads and Rotors (if necessary)

If brake pads are worn:
- Remove the old pads from the caliper bracket.
- Install new pads in the same orientation as the old ones.
If rotors are worn:
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor ensuring proper alignment.

5. Reassemble Brake Components

Caliper:
- Reinstall the caliper over the new brake pads.
- Use a C-clamp to compress the caliper piston if necessary to fit over the new pads.
- Tighten caliper bolts to manufacturer’s torque specifications (typically around 20-30 ft-lbs).

6. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to the manufacturer's torque specification (usually around 76 ft-lbs).

7. Final Checks

Pump the brake pedal several times to ensure proper brake engagement.
Check brake fluid level and top off if necessary.
