Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Components:
- Check for uneven wear on the brake pads and rotors.
- Look for any signs of caliper seizing.
Remove Brake Caliper:
- Use a socket set to remove the caliper bolts.
- Secure the caliper to avoid strain on the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent noise.
- Slide the new brake pads into the caliper bracket.

4. Reassemble Brake Assembly

Reinstall Brake Caliper:
- Carefully position the caliper over the new pads.
- Reattach and torque the caliper bolts to the manufacturer's specifications (typically 25-35 lb-ft).
Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-150 lb-ft).

5. Brake System Check

Pump the brake pedal several times to ensure the pads seat properly.
Check brake fluid level and top off if necessary.
