Abstract
A brake filling apparatus uses nitrogen or dry air as a desiccant to assure freedom from moisture in brake fluid supplied from a supply tank as well as at the filling location. A main fluid tank has a vacuum over the fluid to deaerate the fluid and has a pump submerged in the fluid to deliver fluid to the brake system. The pump is driven by a submerged motor which is driven by pressurized brake fluid. The brake system is evacuated, the low pressure is monitored for a test interval for leak detection, the system is filled by the pump and excess fluid is returned to the main tank and is replaced by the nitrogen or dry air.
