Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Remove Wheels

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

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the mounting bolts with a socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord (avoid stress on the brake line).
Remove the old brake pads from the caliper bracket.
Install new brake pads ensuring they are seated properly.

4. Inspect and Replace Brake Rotors

Check the rotor surface for warping or scoring.
If warped, remove the rotor by unscrewing the retaining screws (if applicable) and slide it off the hub.
Install new brake rotors, ensuring they are clean and free of debris.
Reattach the caliper over the new rotor and secure it with the mounting bolts.

5. Reassemble and Test

Reinstall the wheels and lug nuts, tightening them in a crisscross pattern to the manufacturer’s torque specifications.
Lower the vehicle and reconnect the negative battery terminal.
Pump the brake pedal to ensure proper brake pad seating before road testing.
