Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect the brake pads for excessive wear; if they are less than 3mm thick, replace them.
Sub-steps:
- Remove the caliper bolts using the socket set.
- Lift the caliper off the rotor carefully; support it using a bungee cord or similar to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are correctly positioned.

4. Inspect and Replace Brake Rotors (if necessary)

Check for signs of warping or scoring on the rotors.
If damaged, proceed to replace them:
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Clean the hub surface before installing the new rotor.
- Install the new rotor, securing it with screws.

5. Reassemble and Test

Reattach the caliper over the new brake pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s specified torque value.
Reconnect the battery and perform a brake test to ensure functionality.
