Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen 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 completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if below manufacturer specifications (usually less than 3mm).
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket ensuring they are properly positioned.
- Reinstall caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for scoring or excessive wear.
Replace Brake Rotors:
- Remove the caliper bracket (if applicable) and rotor retaining screws.
- Slide the old rotor off the hub.
- Clean the hub surface to remove rust or debris.
- Install the new rotor and secure it with retaining screws.
- Reinstall the caliper bracket and tighten bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Reconnect the battery.
Test the brakes gently to ensure proper function before driving.
