Replace Brake Pads: If worn, remove the old pads and install new pads ensuring they are correctly oriented. Apply anti-squeal lubricant on the backing of the pads.

4. Inspect and Replace Rotors/Drums

Inspect Rotors/Drums: Check the surface of the rotors for scoring or warping. For drum brakes, remove the drum and inspect the shoes for wear.
Replace Rotors/Drums: If necessary, replace with new rotors or drums. Ensure to torque the rotor or drum retaining screws to the manufacturer's specifications.

5. Reassemble and Bleed Brakes

Reattach the caliper to the bracket using the bolts, torque to specifications.
Reinstall the wheel and lower the vehicle.
Bleed the Brakes: Use a brake bleeder kit to remove any air from the brake lines. Start with the rear brakes and follow the proper sequence as per the manufacturer’s specifications.
