Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent accidental electrical discharge.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.
Tools Required: Jack, jack stands, socket set.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; replace them if they are below the manufacturer's recommended thickness.
Apply brake grease to the back of new brake pads to reduce noise.
Reattach the caliper over the new pads and torque the bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove them by unscrewing the retaining screws using a screwdriver.
Install new rotors, ensuring they are clean and free of grease.
Torque the retaining screws to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 100-120 ft-lbs).
Reconnect the battery and test brake function before driving.
