Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Raise the Vehicle

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

3. Remove Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper away from the rotor and support it (do not hang it by the brake line).
- Remove the old brake pads from the caliper bracket.
Brake Rotors:
- If replacing, remove the rotor retaining screws (if equipped) and slide the rotor off the hub.

4. Inspect and Replace Components

Brake Pads:
- Compare new brake pads with old ones for size and thickness.
- Install new brake pads into the caliper bracket.
Brake Rotors:
- Clean the hub surface and install the new rotor onto the hub.
- Torque the rotor retaining screws to manufacturer specifications (typically between 10-15 ft-lb).

5. Reassemble and Test

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lb).
Repeat the process for all wheels.
Reconnect the battery.
