Solution

1. Preparation

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

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Check the caliper slides for proper lubrication; apply brake grease if necessary.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors

Check the rotors for any signs of scoring or uneven wear.
If damaged, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install new rotors, ensuring they are clean and free of any debris.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque settings.
Reinstall the wheels and lower the vehicle back to the ground.

6. Bleed Brake System (if necessary)

If brake fluid was lost during the process, bleed the brake lines to remove any air.
Use a brake bleeder kit for this process, starting from the wheel farthest from the master cylinder.
