Reverse Fluid Injection or RFI injects fluid at the low points, the slave bleeder valves. RFI takes advantage of the "laws of Physics": air rises in fluid. The complete system is bled by forcing the air up and out the master cylinder reservoir. The brake fluid then fills the reservoir.
RFI does not require special tools or clips. Heres why. RFI 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 providing minimal resistance to fluid as it returns to the master cylinder following the release of braking pressure.
RFI and Contamination "The Phoenix Injector generates less than 10 psi during the RFI process. Our testing has shown that this amount of pressure has no chance of forcing contaminates upstream to other brake components. This combined with the fact that the process would be used after the system has been flushed virtually eliminates any threat."
Bill Williams, President WISAT
Vacuum 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.


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 fluid to the master cylinder.
