Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues during the repair.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Pads

Inspect: Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor. Check the brake pads for wear indicators.
Replace: If pads are worn down, remove them from the caliper bracket. Install new brake pads, ensuring they are properly aligned.

5. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.

6. Reassemble

Reattach the brake caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's specified torque value (usually around 30-40 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.

8. Final Check

Reconnect the battery.
Pump the brake pedal a few times to ensure proper seating of the pads and restore brake pressure.
