Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical issues.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Clean Brake Components

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
Inspect the brake pads for wear; replace if necessary.
Clean the caliper bracket and sliding pins with brake cleaner.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Install new brake pads in the caliper bracket, ensuring correct orientation.
If applicable, apply brake grease to the backing of the pads to reduce noise.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to the specified torque (typically 76 ft-lbs).

6. Brake Fluid Check (if necessary)

Inspect brake fluid levels in the reservoir; top off with the manufacturer-recommended brake fluid if low.

7. Test Drive

Lower the vehicle, reconnect the battery, and take the car for a test drive to ensure brakes are functioning properly.
