All,
I am preparing to replace Brake Master Cylinder with ABS on 2007 F-150 Truck. So, I decide to research the subject to see what was the best practice that I could I apply to truck and the 1973 mustang.
I processed a search of the Suspension, Handling, and Brakes threads and found the sound typical processes in Master Cylinder, brake line, and caliper brake fluid bleeding.
I wanted to find something that would provide a powered vacuum DYI type system to aid in the bleeding of the brake system.
So, I was looking around the internet and found the Phoenix Systems RFI brake bleeding system. Huh, maybe I was doing the process wrong to start with.
Reverse Bleeding
Reverse Bleeding injects fluid at the low points, the slave bleeder valves. Reverse Bleeding 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.
This tells me that when I would be trying to force the air downward with the fluid out of the calipers and wheel cylinders, I would not get all of the air bubbles out due to the air fighting to move upwards. Duh moment here!
1: Reverse feed the brake fluid back towards the Master cylinder
2: Afterwards, reverse the process and vacuum the fluid back through. (Standard Practice that we have all followed).
Here is the You Tube on the PHOENIX SYSTEMS V12-DIY BREAK BLEEDER Kit- This kit has been discontinued. If you do a Google search, one can find this kit on EBay, Summit Racing, and Jeggs.
Another You Tube video that I found interesting was the process in which wheel to start bleeding the system from. Typically, we start from the furthest point which would the right rear wheel.
This persons process started with the LF first. Wait a minute. I have always been told to start with the furthest point first.
His reasoning was sound. Why would I want to run the old contaminated fluid and trash thorough out the brake system? Makes sense! So, I f I start the Left Front (LF) port, closet to the Master Cylinder, I will drain all of the contaminated brake fluid out. So, when bled the rest of the brake system, I will bleed it with fresh brake fluid.
He stated that this works best for him. But, it is some good sound thinking.
Start with the LF, then to the RR, next to RF, and final bleed to the LR.
I know that the Suspension, Handling, and Brakes section has look of good information. As I stated at the beginning, I searched the on Brake threads and I did not see any threads related to Reverse Fluid Injection (RFI) of the brake fluid bleeding process.
Another source who tested this practice.
