Brake Washers
PREPARATION
• The Truck Brake Washer is shipped fully assembled. An Oil Magnet™ is in the basin. The Oil Magnet™ will absorb any free oil. A disposable cloth Primary Microfilter is under the grille. A reusable, stainless steel and plastic prefilter rests upon the grille. A black rubber pad serves as a drain pan during cleaning and a cover when the machine is not in use.
• Follow chemical manufacturer’s instructions to prepare a working solution of cleaner for the machine. When possible, pour the solution through the filter to fill the basin with 6.5 gallons (25 liters). Pouring through the filter prevents liquid from splashing. When the basin is full, the filter is partially under water.
• Place the stainless wire mesh prefilter on the grille.
• Insert a compressed air quick-disconnect plug (not included) into the hose extending from the pressure regulator. The factory-supplied fitting at the end of the hose is ¼" NPT.
• Attach a compressed air line to the quick disconnect plug.
• Depress the triggers on both tools to purge air from hoses and to fill them with solution.
• The Truck Brake Washer is now ready for use.
OPERATION
Some shops remove the tire and the drum (or drum and hub) in separate operations. Other shops use a wheel dolly to remove them as an assembly in one operation. Use the method that best suits the work performed in your shop.
If your shop removes the tire and the drum in separate operations:
• Remove the tire. Use a dolly or get assistance in lifting heavy tires and wheels.
• Roll the Truck Brake Washer under the drum.
• Before attempting to remove the drum, use the Injector Nozzle to saturate the inside of the drum, wetting the brake shoes and flushing the drum.
• Once you have thoroughly saturated the brakesand drum, slide the drum back 3 to 5 cm. Continue flooding the brakes to suppress any dust that remains.
• Remove the drum
• Use the brush to clean the brakes and the drum.
If your shop removes the tire and the drum (or drum and hub) in one operation:
• Before raising the vehicle, roll the Truck Brake Washer under the axle.
• Place the edge of the black neoprene cover between the drum and wheel with the opposite end resting on the Truck Brake Washer. It will serve as a drain board to channel solution from the drum back into the Truck Brake Washer as you wet the brake parts and drum.
• Use the Injector Nozzle to saturate the inside of the drum, wetting the brake shoes and
flushing the drum.
• Remove the Truck Brake Washer from under the vehicle.
• Raise the vehicle and place safety stands under the axle.
• Follow normal shop procedure to remove the tire, drum and hub.
• Use the brush to thoroughly clean the brakes and drum.
