A brake filling method and 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 (24) has a vacuum over the fluid to deaerate the fluid and has a pump (32) submerged in the fluid to deliver fluid to the brake system (18). The pump (32) is driven by a submerged motor (34) 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 (24) and is replaced by the nitrogen or dry air. |
