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.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brakes are squeaking.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, loosen and remove the lug nuts from the wheel.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for wear indicators and measure thickness. If pads are below the manufacturer's recommended thickness (typically 3mm), replace them.
Remove Brake Caliper:
- Use a socket wrench to remove the caliper mounting bolts.
- Carefully slide the caliper off the brake pads and suspend it using a bungee cord to avoid straining 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 back of the new brake pads to prevent squeaking.
- Slide the new pads into the caliper bracket.

5. Reassemble Brakes

Reinstall Brake Caliper:
- Position the caliper over the new pads and secure it by tightening the caliper mounting bolts to the manufacturer's specified torque.
Reattach Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
Lower the Vehicle:
- Carefully lower the vehicle from the jack stands and remove the hydraulic jack.

6. Final Checks

Tighten the lug nuts to the manufacturer's specified torque value.
Check the brake fluid level and top off if necessary.
