Phoenix bleeder question

[Garagebound1]

I've used my Phoenix reverse bleeder with good results but I have a question I haven't heard answered. I built a whole brake system on a home built car and with Wilwood components everything worked good. I had a Land rover that blew a line. I replaced all of the brake lines and bled them by gravity, also a Motive and then a Phoenix. I had pedal go to floor first pump them lock wheels second pump. I ended up taking it to a dealer and they replaced master and and unit. My question is, is the Phoenix ok to use with and units? I know there are valves in the and but I'm not sure how they operate. Also not sure if the gigantic bill was legit either.

Reverse-bleeding is a fine practice...IF THE BRAKE FLUID HAS ALREADY BEEN FLUSHED so that the fluid in the system isn't contaminated.

IF (big IF) the fluid in the brake system is contaminated--and it is unless it's been freshly flushed--the worst fluid is generally in the lowest spots--the wheel cylinders. Reverse bleeding pushes the worst fluid back through the ABS valves, combination valve/proportioning valve/holdoff valve, and into the master cylinder.

they replaced master and and unit.

What does that mean?

My question is, is the Phoenix ok to use with and units?

What is an "and unit"?






Wild guess--the system emptied, the master cylinder got air in it, and should have been bench-bled before screwing with the rest of the system.

Damn auto correct. They replaced master cylinder and ABS unit. That was after I replaced every brake line. So I'm not sure how there could have been anything in system. I was wondering if the Phoenix would have a negative effect on the ABS unit.
