Even if done correctly, however, manual bleeding can cause problems. Under normal conditions the master cylinder piston only travels a small part of the full travel. The rest of the cylinder wall never comes into contact with the master cylinder piston. As a result, there is no opportunity for any possible corrosion on the wall of the cylinder to be removed. If the system is bled by pushing the piston through its entire range, corrosion can become trapped between the piston seal and the cylinder wall, rendering the master cylinder inoperative. Manual bleeding also requires careful checking of the fluid reservoir to ensure that it is not “pumped dry.” Each time the reservoir is emptied, it must be refilled, which presents an opportunity for spilling corrosive hydraulic fluid.

Motive Products POWER BLEEDERs™ allow one person to easily, safely, and effectively bleed hydraulic braking and clutch systems. Bleeding has never been easier. There’s no need for a helper to constantly pump the pedal while you open and close the bleed valves. And the large capacity 2 liter tank prevents the need for constant refilling of the fluid reservoir, avoiding corrosive spills. The precision pressure gauge ensures safe and effective bleeding every time.

Works with all Watercooled Models as well as European (Ate) Systems
