Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

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

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness; if less than 3mm, replace.
- Look for uneven wear patterns.
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new pads, ensuring they are seated properly.
- Reattach the caliper and tighten bolts to manufacturer specifications (typically around 20-25 ft-lbs).

5. Inspect and Resurface or Replace Rotors

Inspect Rotors:
- Check for grooves, rust, or warping.
If Necessary:
- Remove rotor retaining screws and slide off the rotor.
- If rotors are within specification, consider resurfacing; if not, replace with new rotors.
- Install new or resurfaced rotors, ensuring they are properly seated.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer specification (typically around 76-80 ft-lbs).

7. Final Check

Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
