Avoid contact with brake fluid, water, soap, thinners, abrasives, etc… This plating becomes tougher with age, but is very vulnerable when fresh. Certain fluids and abrasives, including wax, may remove the gold coating. When your booster needs wiping off, use a towel with a slight dampness to accomplish this. Spraying a clear coat on will neutralize the red and green colors in the plating. If in doubt, call or e-mail me first.
Silver and Black
Keep clean with moist cloth. Wipe off any foreign liquids. These parts may be clear coated, if desired.
Gray & Black Phosphate
This plating should be kept clean and dry. There should be a light coat of oil on all surfaces. Lube hinge pivots with a suitable grease prior to installation.
Care for chrome plated brake boosters and other parts is best accomplished with wax and chrome polish. Keep surfaces dry and clean for a longer lasting finish.
