Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope (do not let it hang on the brake line).
- Inspect brake pads for thickness; replace if they are below the manufacturer’s recommended thickness (usually around 3mm).
Replacement:
- Remove old brake pads by sliding them out of the caliper bracket.
- Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for scoring or excessive wear. If damaged, they should be replaced.
Remove the rotor by unscrewing the rotor retaining screws (if equipped) and sliding it off the hub.
Clean the hub surface and install the new rotor, ensuring it is seated properly.

5. Reassemble Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (typically between 20-30 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to the specified torque (usually around 80-100 ft-lbs).

6. Test Brakes

Lower the vehicle and pump the brake pedal several times to seat the pads properly.
Check brake fluid levels and top off if necessary.
