May need to rebuild the hydrovac unit in a 57 GH. Anyone have
recommendations for a good rebuilder?
Also would like to change the MC over to a dual chamber one. Will this have an impact on the hydrovac working properly?

I had mine rebuilt by Miwest Remanufacturing In Bedford Park, Ill..Was around $325 with shipping. Haven't installed it yet..But when I sent it, its was full of rust and didn't look too healthy. They rebuilt it, sent it back looks like

If you go to a dual chamber master cylinder and retain the Hydrovac, you're only going to have power brakes on the line you put it on, front or rear. Otherwise, you'll have to use a second unit on the other line to have power brakes all the way around.

We'll, I sure don't want two of them in the engine compartment!!
I'll have to check and see what other options there are for power brakes and a dual MC.

There are dual hydrovacs available from the street rod guys for dual chamber master cylinders, but they are pricey and you have to put them in your trunk or under the car. There is no good fix for power brakes/hydrovacs on Hawks. I have good working hydrovacs (with single chamber master cylinders) on both of my 64s and they work fine. The last one I had redone by JP's guy. I am not sure if JP is still doing hydrovac rebuilds or not but they sure look nice and they did a far better job than the one I had rebuilt a few years ago from a power brake vendor in FL.

My guy is still rebuilding them for me, but I only sell direct to vendors after the copper washer issue made me realize that selling wholesale on the net was not worth the risk of bad press in case of a real or perceived defect.

I want to look into options for removing Hydrovac completely. Maybe a firewall mounted booster and MC (swinging pedal) or just change the frame mounted mc to the correct dual chamber one?
