Proper Bleeding of Hydraulic Systems Using a POWER BLEEDER^TM:

As part of a thorough annual maintenance regimen or whenever a hydraulic system is opened and air introduced into the lines (i.e. during replacement of a master cylinder, caliper, fluid line, etc.), air must be bled from the system.

Without a POWER BLEEDER^TM, bleeding the hydraulic system requires two people; one pushes down on the brake pedal while the other opens a bleed valve at the wheels or clutch slave cylinder. With one end of a piece of tubing attached to the bleeder valve and the other submerged in fresh hydraulic fluid, the brake pedal is repeatedly depressed and then released while the bleed valve is alternately opened and closed. Without this two-person process, dirty or air contaminated brake fluid can get sucked back into the wheel cylinder, caliper, or slave cylinder.

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^TM 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.
