hydroboost brakes
Those of you running a hydratech brake system, was wondering how long it to before you had no air bubbles in the lines and therefore had amazing brakes and still good steering? I have put a few miles on mine but the pedal is still slow to return and cuz of that I get a little of what I think is called bump steer. I think co425 has this system. Ill wait for him to chime in. I have a gm saginaw brand new pump on mine so I have plenty of pressure.

It takes a bit of driving to get it fully bled. I drove around 150 miles on a hunting trip after the install and it finally got all the air out. You can get it bled faster by doing a lot of turning and stopping at the same time.

Mine took almost no time to bleed. The first time I drove it, I had incredible brakes and haven't looked back. Even when I've removed the pump for something or other and drained the fluid, as soon as it gets SOMETHING in there, I have good brakes, even if the fluid level is low enough that the pump is moaning.
I've always just turned the wheels back and forth a few times in the drive way so I didnt have any obvious tight spots that could be dangerous driving in the neighborhood and then driven.
I have seen some people complain about some VERY hard to bleed systems that have required lifting the front ends and tapping on parts with hammers while someone else moves the wheel, but maybe I've been exceptionally lucky?

Now that I think more about it, it was harder for me to bleed when I had a small reservoir on the pump; I DID have a hard time with the stupid dinky one that looks like it should be part of a remote mount system and had to pour fluid into the pump AS it was running to get it sorted out.
It's my experience that the more fluid capacity you have sitting on the pump, the easier things will be for you. I have a reservoir off of some late model Chevy truck now and it's about the size of the "Canned ham," pumps AND fits on my Cummins engine without the interference that the other style has.
