Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect Brakes

Examine the brake pads; if less than 3mm thick, replace them.
Check the rotors for grooves or excessive wear; replace if necessary.
Look at the calipers for any signs of sticking; free them if jammed.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads and install new ones, ensuring proper orientation.
Reinstall the caliper and torque the bolts to manufacturer's specifications (typically around 25-30 Nm).

5. Replace Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing the retaining screws.
Install new rotors, ensuring they are clean and free from grease.
Torque the retaining screws to the manufacturer's specification (usually around 10-15 Nm).

6. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specification (typically around 120 Nm).
Lower the vehicle and reconnect the battery.
Pump the brake pedal to ensure proper brake pad seating.
