Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts with a socket set.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for wear and clean it if necessary.
Install new brake pads, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for any grooves or uneven surfaces.
If replacement is needed, use a rotor puller to remove the old rotor.
Install the new rotor, ensuring it is properly aligned.

5. Reassemble and Test

Reposition the caliper over the new brake pads and secure it with bolts to the specified torque value (typically around 25-35 Nm).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 90-120 Nm).
Reconnect the battery and perform a brake test before driving.
