Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Remove Wheel

Loosen the lug nuts using a socket set.
Elevate the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bracket bolts using a socket set.
- Lift the caliper off the rotor, supporting it with a bungee cord.
- Remove old brake pads from the caliper bracket.
- Install new brake pads ensuring correct orientation.
Brake Rotors:
- If rotors are damaged, remove them by unscrewing the rotor retaining screws (if equipped) and sliding the rotor off the hub.
- Clean the hub surface before installing the new rotor.
- Install the new rotor, ensuring it is seated properly.

4. Reassemble Brake Components

Reposition the caliper over the new brake pads and rotor.
Tighten the caliper bracket bolts to the manufacturer’s specified torque (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (generally around 100 Nm).
Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads against the rotor.
