Hi all,
I’ve done a custom hydroboost brake set up in my ‘68 coronet and it brakes amazingly.
But, I can’t use the car as the fluid keeps over flowing and I think it’s due to the fluid foaming / frothing.
The set up is a hydroboost from a Silverado or similar. Runs off the stock Saginaw pump, into the hydro, pressure out to borgeson steering box return back to the Saginaw return, borgeson return goes into an oil cooler then into an additional reservoir on the fire wall, then back to an addition AN return nipple in the side of the Saginaw.
I have tried thick steel wool in the reservoir and that seemed to work, but after a short test, I did find the steel wool being sucked into the outlet to the pump.
So I made a baffle set up with a length of all thread and three sheets of mesh. Garage test looked good, but the drive test saw it overflowing again.
After running you can hear the system is pressurised and pushing fluid out of the Saginaw cap.
At this point I am thinking:
do I need to sand which steel wool inbetween the mesh plates?
Do I need to find a way to seal the system? So try and seam the Saginaw pump?
Or if I can’t seal the Saginaw do I need to find another modern pump that either uses the remote reservoir or integrated one but seals?
Also going to try and retighten all the fittings as well.
But I’m struggling here, could really do with some advice/help!
