Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Brake Pads

Jack up the vehicle: Use the jack to lift the front or rear (depending on which wheels are affected) and secure with jack stands.
Remove the wheel: Use a lug wrench to loosen and remove the wheel nuts, then take off the wheel.
Inspect brake pads: Check the thickness of the brake pads. If they are below the minimum thickness (usually around 3 mm), they need to be replaced.
Remove caliper: Unscrew the caliper bolts and carefully lift the caliper away from the rotor. Suspend it with a bungee cord to avoid strain on the brake line.
Remove old pads: Slide the old brake pads out of the caliper bracket.
Install new pads: Insert new brake pads into the caliper bracket, ensuring they match the old ones in orientation and fit.

3. Inspect and Replace Brake Rotors (if necessary)

Check rotors: Inspect the surface of the rotors for grooves or warping.
Remove rotors: If replacement is necessary, remove any retaining screws and pull the rotor off the hub. You may need a hammer to gently tap if it is stuck.
Install new rotors: Place the new rotor onto the hub, securing it with retaining screws as necessary.

4. Reassemble and Test

Reattach caliper: Place the caliper back over the new pads and secure it with bolts. Torque the caliper bolts to the manufacturer’s specifications.
Reinstall wheel: Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle: Remove jack stands and lower the vehicle back to the ground.
Torque lug nuts: Finish tightening the lug nuts to the manufacturer’s specifications.
