Wear safety glasses and gloves throughout the procedure.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel covers or hubcaps if applicable.

3. Remove the Brake Wheel Assembly

Use a socket set to remove the lug nuts and take off the wheel.
Detach the brake caliper by removing the caliper mounting bolts.
- Tools Required: Socket set
- Safety Warning: Support the caliper with a bungee cord to avoid strain on the brake line.

4. Inspect and Replace Brake Components

Inspect brake pads for uneven wear; replace them if necessary.
- Parts Required: New brake pads
Check the brake rotor for warping or scoring; replace if necessary.
- Parts Required: New brake rotors (if warped)
Clean the caliper and ensure it slides freely on the mounting bracket. Apply brake grease as needed.

5. Reassemble the Brake System

Reinstall the brake caliper and tighten the mounting bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reattach the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.

Carefully lower the vehicle back to the ground.
Remove the jack stands.

7. Final Checks

Pump the brake pedal several times to ensure proper brake function before driving.
Check the brake fluid level and top up if necessary.
