Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Remove Wheel

Use a lug wrench to loosen the wheel nuts while the vehicle is on the ground.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the wheel completely to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord or wire (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket and replace any worn or damaged components.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Inspect and Replace Rotors

Check the brake rotors for uneven wear or scoring. If necessary, replace the rotors.
Use a torque wrench to loosen and remove the rotor retaining screws, if applicable.
Clean the hub surface to ensure the new rotor sits flush.
Install the new rotor, securing it with the retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque value (refer to the service manual).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and securely tighten the lug nuts in a criss-cross pattern to the specified torque.
