ABSTRACT:
A Brake Flush Accelerator (BFA) selectively depresses a brake pedal while the master cylinder reservoir is under pressure from a brake flush machine, forcing fluid through the system at a very rapid rate. The BFA also provides a thorough flush as internal hydraulic pressure from the master cylinder can be used to exert force to remove contaminates from the brake system. The BFA exposes the low
o pressure area of the master cylinder to fluid flow from the pressurized master cylinder. When the brake pedal is depressed, a port in the master cylinder is opened which exposes the low
o pressure area of the master cylinder to fluid flow from the pressurized master cylinder reservoir. The BFA receives its pneumatic power from an air compressor or is easily adapted to a car tire. The BFA can be powered directly from the brake flush machine or attached to a vehicle's battery.
