Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

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 Replace Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Lift the caliper off the rotor and secure it with a bungee cord to prevent strain on the brake line.
- Remove the old brake pads and install new ones, ensuring they are properly seated.
Brake Rotors:
- Check the rotor surface; if damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor, ensuring it fits snugly.

4. Reassemble Brake System

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and remove jack stands.
Torque the lug nuts to the manufacturer’s specification (usually 76-85 ft-lbs).
Reconnect the battery.
