Solution

1. Preparation

Park the vehicle on a level surface and ensure it is in gear or in "Park."
Gather necessary tools and safety equipment.
Wear gloves and safety glasses for protection.

2. Lift the Vehicle

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

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket.
- Tools Required: Socket set, torque wrench
Slide the caliper off the rotor and suspend it with a bungee cord (do not let it hang by the brake line).
Inspect brake pads for wear; replace if they are below the minimum thickness (usually 3mm).
- Parts Required: New brake pads
Apply brake grease to the back of the new pads to reduce noise and install them in the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the thickness of the rotors using a micrometer; replace if below the manufacturer's specifications.
If replacement is needed, remove the rotor by unscrewing the retaining screws or bolts.
- Parts Required: New brake rotors
Install the new rotor and torque to the manufacturer's specifications.

6. Reassemble Brake Components

Reattach the caliper over the new pads and rotor, securing it with the caliper bolts.
Use a torque wrench to tighten the caliper bolts to the manufacturer's specification.

7. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque.
