Brake Disks Treated with Zinc Dust Spray Paint



Spray brake disk friction rings (Figure 1) of vehicles parked for an extended time with zinc dust spray paint. Apply it to various points on the outside



and inside throughout the brake rotors. By turning the wheel or moving the vehicle a few yards, the dust will spread across the entire friction ring.



This zinc dust is essential in protecting from corrosion and preventing shuddering and squeaking.
