Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery to avoid any electrical issues during repairs.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel where the brake pads will be serviced.
Jack up the vehicle and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool to avoid strain on the brake line.
Inspect Brake Rotor:
- Check the rotor for signs of warping or scoring. Replace if necessary.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.

4. Reassemble Components

Reinstall Brake Caliper:
- Slide the caliper back over the new brake pads.
- Reinstall caliper mounting bolts and torque to manufacturer specifications (typically 25-30 ft-lbs).
Reattach Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 76-80 ft-lbs).

5. Test Brake System

Reconnect the battery.
Pump the brake pedal several times to ensure pads are seated correctly.
Check brake fluid level and top off if necessary.
