Reverse Bleeding Does Not Require Special Tools Or Clips

Reverse Bleeding utilizes fluid paths in which enhanced braking mechanisms offer almost no resistance. Metering valves, proportioning valves, and anti-lock valving are designed to manipulate braking pressure, while proving minimal resistance to fluid as it returns to the master cylinder following the release of braking pressure. During pressure bleeding the fluid in the reservoir is pressurized. The pressurized fluid is allowed to pass through the master cylinder to the bleeder valves. When the bleeder valves are opened, the pressurized fluid and air will be forced out the bleeder valves. During vacuum bleeding negative pressure is exerted on the system from each of the bleeder valves. This negative pressure or vacuum draws the fluid from the reservoir, through the system and out the bleeder valves. This goal of bench bleeding is to remove all of the air from the component prior to its installation. The master cylinder is usually placed in a vice and a combination of Reverse Bleeding and Pressure bleeding is usually used. The Phoenix Injector™ is unparalleled in bench bleeding any master cylinder, especially 2 and 4 outlet quick-take-up master cylinders used by Ford, GM, Chrysler, and some imports. A technique developed by Phoenix Systems uses the Injector to create pulsations which generate a force within the system which acts to overcome the surface tension of the trapped air. This Pulse Generation helps to force trapped air out of a system. It’s like tapping on a caliper, slave, master or line, at the same time. When replacing calipers or wheel cylinders on vehicles equipped with a “front-to-rear-split” hydraulic system, you can utilize a cross bleed procedure to remove the majority of the air making the remaining bleed and flush procedure easier. Fluid is injected into a caliper or wheel cylinder to the opposing caliper or wheel cylinder. This will bleed and flush that portion of the hydraulic circuit. A brake pedal depressor is used to prevent the return of trapped air.

Reverse Bleeding is Phoenix System’s patented bleeding technique that allows the user to efficiently remove trapped air from a brake system. Phoenix Systems recommends thoroughly flushing contaminated systems of all old fluid before performing Reverse Bleeding on brake and ABS systems. The Phoenix brake/clutch bleeders are especially useful in bleeding ABS and Ford Ranger clutches. Designed for one person to bleed without air or electricity, they are fast and efficient, and most systems can be bled in 10 minutes.
