Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Socket set, torque wrench
Loosen the lug nuts on the wheel using a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper mounting bolts using a socket wrench.
Carefully lift the caliper off the rotor and support it with a wire or bungee cord (do not let it hang from the brake line).
Remove the old brake pads from the caliper bracket.
Compare new brake pads to the old ones to ensure correct fit.
Apply brake grease to the backing of the new pads to prevent noise.
Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves and warping.
If damaged, remove the rotor by unscrewing the rotor retaining screws (if applicable).
Clean the hub surface with brake cleaner to ensure proper contact.
Install new rotors, ensuring they are properly aligned.
Torque the rotor screws to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and secure it with the mounting bolts, torquing to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the negative battery terminal.
