I finished up my hydroboost install today and ran into some troubles. Here is where I stand.
All lines are correct.
My Hydroboost unit does not have an accumalator.
The pump SCREAMS when I rev up the engine. Its fine at an idle.
I have power brakes, but a TON of travel in the pedal.
I have no power steering.

The pump is new, for an 85 Grand National. The Hydroboost unit is from a Grand National, was said to be in working condition. The gear box is also from a grand national.

I really dont know where to start.
Any help or suggestions would be appreciated, im just frustrated.:guilty:

That should be an electrically driven Powermaster system if it is a stock GN piece? Is the fluid frothy?

Fluid is good. In 85 it was a straight Hydroboost system. Other years of GN use the Powermaster system.
