Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle depending on the affected brakes.
Secure the vehicle with jack stands to prevent movement.

3. Remove Wheel

Use a lug wrench to 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 set.
Carefully lift the caliper away from the rotor; support it using a bungee cord to avoid stress on the brake line.
Remove old brake pads from the caliper bracket.
Compare new pads with old ones; ensure they are the correct size.
Install new brake pads, ensuring they fit snugly in the bracket.

5. Inspect and Replace Rotors (if necessary)

Check the rotor surface; if scored or warped, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface before installing the new rotor.
Install the new rotor, ensuring it is properly seated.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle and Final Checks

Carefully lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications (typically 76-83 ft-lbs).
Pump the brake pedal a few times to seat the brake pads.
