Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper by unscrewing the mounting bolts with a socket wrench.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stressing the brake line.
- Remove the worn brake pads from the caliper bracket.
- Compare new pads with old ones to ensure proper fit.
- Install new brake pads ensuring they are properly aligned in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor for any grooves or damage. If damaged, remove it by unscrewing the retaining screws or bolts.
- Clean the hub surface to remove rust or debris.
- Install the new rotor, ensuring it is seated properly against the hub.

5. Reassemble Components

Sub-steps:
- Reinstall the brake caliper over the new pads and rotor.
- Torque the caliper bolts to the manufacturer’s specifications (usually around 20-25 Nm).
- Reinstall the wheel and torque the lug nuts to the specified value (typically 90-110 Nm).

6. Reconnect Battery and Test

Reconnect the battery and lower the vehicle.
Test the brakes at low speed to ensure proper function and listen for any abnormal noises.
