Hydroboost question, anyone else have this problem?

[datsbad]

We instaled a Hydroboost set up on a customers car . One small problem we are having is a slight twitch when the brakes are applied.

Brakes are bleed great , hydorboost is bleed also, No air in PS res . Has anyone else had this problem?

The twitch is slight but isnt right. Moving the car slow speeds it is very annoying. Hydratech is about impossible to get a hold of these days.
Any thoughts would be great

I too had that for a while until all air (micro bubbles per Paul) was purged out of the system. Paul at Hydroboost called it 'kickback' and it went away. Happened every time I opened the system up (due to power steering issues).

I've installed a few of the setups, some bleed faster than others. They all had the issue at first. Sometimes it's gone after one test drive, another car took a week or so of short drives. The Hydroboost works great are on all the cars now. I reccomend it to everyone with power steering.
