For those of you that have a Hydroboost unit with 4 bolts that secure it to the firewall, do you just remove the mounting plate that bolts to the firewall by removing the 4 screws under the dash? Don't want to get under there and fight with it if that's not the right course of action. Also, I'm looking for an excuse to stop for the night and this seems like a good one as I'm covered in grease and don't want to get any on the interior. ;-)
I bought a new gasket so that will get done as well. Thanks!Yes. That’s how you remove the mounting plate. I’d recommend replacing the gasket while you have it pulled off.

Spent a little time on the conversion tonight. Managed to get bolts off 3 of the 4 studs holding the old firewall plate in place... the 4th stud is held in place by a push nut that doesn't want to budge. Will fight with that tomorrow. The little annoyances and setbacks never seem to end with this project. It'll be worth it in the end though.
I got the push nut off after lots of twisting, bending, cursing, and the application of many tools.
The mounting plate on the firewall still won't come off. I don't know what's holding it. I am at a loss?
Thoughts?
It is time for a drink.
How do you have the return to the reservoir plumbed? It could be too small and causing a restriction. Is it tee'd where it could be restricting flow? Make it to where the return gets back to the res easily.I have the hydrotech unit, and for the life of me i cannot get it to stop whining, it also whines when i press the brake pedal at idle. i have talked to jim repeatedly and i have replaced the valve with the flow adapter in my PS pump, i have an lines to the pump for high pressure and an lines to the gear box and just cannot get it to stop the noise...so damn frustrating, i used the concept one ps reservoir as well..

@Cryptic @TexasT All 4 bolts are undone along with the pedal. Powermaster unit has been off for awhile, it's just the plate now. Good to know that nothing else should be holding it in place; I didn't want to be more aggressive than I've already been if there was anything else to remove. I've been prying on the mounting plate with 2 large ~18" screwdrivers between it and the firewall and the bottom 2 bolts won't budge, the top 2 are free. I think the plate is now slightly bent (hopefully not the firewall) from all the prying. I've also hit the bottom bolts with a long punch and hammer from inside the car to try and motivate it. When I get back to it tomorrow I'll go around the entire perimeter of the plate again to see where it might be held up.
I was expecting something with this conversion to be super frustrating but this was not the part I thought would be an issue.
There’s always something frustrating with brakes I‘ve found and it’s usually something dumb.
Below are the schematics from the service manual. As you can see it’s just the four bolts.
Agreed on that point. I had a heck of a time getting the brake line I had to cut straight enough to slip a new tube nut on before I could flare it. Flare didn't come out great so I'll probably need to do another round of straightening, cutting, and flaring. Fun times.
Thanks for the pic and the reassurance! Not sure why there was a push nut on one of the bolts instead of a nut. I'm going to have to find a copy of that service manual for my shop.
