Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a socket set to loosen lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor.
- Check the pads for wear; replace if they are below the minimum thickness (usually 3mm).
Brake Rotors:
- Inspect the rotor surface for any grooves or scoring; replace if damage is present.
- If rotors are within spec, consider resurfacing if applicable.
Calipers:
- Check for proper movement of the caliper piston; replace caliper if it is seized.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads, remove the old pads and install new ones, ensuring they are properly seated.
If replacing rotors, remove the old rotor and install the new one, securing it with the appropriate torque specifications (usually around 80-100 ft-lbs, but refer to manufacturer specs).

5. Reassemble and Test

Reinstall the caliper over the new pads or rotor.
Tighten caliper bolts to manufacturer specifications.
Replace the wheel and tighten lug nuts in a star pattern to the recommended torque (usually around 100-110 ft-lbs).
Reconnect the battery and lower the vehicle.
