Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
- Use the jack to lift the vehicle and place jack stands for safety.
- Remove the lug nuts with the lug wrench and take off the wheel.

3. Inspect and Remove Brake Components

Tools Required: Socket set, torque wrench
- Inspect the brake pads and rotors for wear.
- Remove the caliper bolts using the socket set and carefully take off the caliper.
- Secure the caliper with a bungee cord or rope to avoid stress on the brake line.

4. Replace Brake Pads and/or Rotors

Tools Required: Brake pad spreader, rotor puller (if needed)
- If the pads are worn, replace them with new ones, ensuring they are compatible with the model.
- If the rotors are scored or worn, replace them as well, following the manufacturer’s specifications.
- Use the brake pad spreader to compress the caliper piston if necessary.

5. Reassemble Braking System

Tools Required: Torque wrench
- Reinstall the caliper and tighten the bolts to the manufacturer’s torque specifications.
- Place the wheel back on and hand-tighten the lug nuts.

6. Lower Vehicle and Reconnect Battery

Carefully remove jack stands and lower the vehicle to ground level.
Reconnect the battery and ensure all electrical components are functioning.
