Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts with a socket set.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the braking components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor.
- Inspect brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Check for scoring or warping. Measure rotor thickness with a micrometer.
- Replace if below manufacturer specifications or if damaged.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads:
- Remove old pads and install new ones.
- Apply brake grease to the backing plate of new pads to reduce noise.
If replacing rotors:
- Remove the old rotor and install the new one, ensuring it is properly aligned.

5. Reassemble Braking System

Reattach the caliper and tighten bolts to the manufacturer’s torque specifications.
Reinstall the wheel and tighten lug nuts in a star pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
