Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to prevent movement.

3. Remove Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Check the brake pads for wear; if they are worn down to the metal, replace them.
- Sub-steps:
  - Pull out the old brake pads and clean the caliper bracket.
  - Insert new brake pads ensuring they are properly seated.
If the pads are in good condition, check for proper lubrication on caliper slides.

5. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for grooves or warping.
If damaged, remove the rotors by unbolting them from the hub.
- Sub-steps:
  - Clean the hub surface with a wire brush.
  - Install new rotors, ensuring they are torqued to manufacturer specifications.

6. Reassemble Components

Reattach the caliper to the rotor and secure it with bolts.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.

7. Final Checks

Before driving, pump the brakes to ensure the pads are seated properly.
Check brake fluid levels and top off if necessary.
