Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

Using a socket set, loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads; replace them if the friction material is worn down to 3mm or less.
Brake Rotors:
- Check the rotors for grooves or wear.
- If damaged, replace the rotors.
- If they are within specifications, clean them with brake cleaner.

4. Reassemble Components

Replace any worn brake pads and/or rotors.
Reinstall the caliper and torque the bolts to the manufacturer’s specifications (commonly around 25-35 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to ensure even pressure.

5. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper caliper and pad seating.
Check brake fluid level and top off if needed.
