57 Custom 300 312 4V power brakes?

[Edd505]

tomsclassic  ebay had a unit hat fit with minor modification.  The bracket to firewall holes need elongated to match the the firewall, simple fix.  Next question, with the duel reservoir will I need a proportioning valve?

I have the booster in and plumbed to the original lines on the frame front and rear.  Then it was what about the brakes switch and thought about a T in either of the lines at the brake cylinder.  Will that work or do I need to find another way,

That booster is how close to the exhaust manifold?  Was your car a power brake car to start with?

[Edd505]

This was the best I could get I can try again if you need more pictures.

Thank you.

Did you get the booster to work and if so how does it feel?    I'm wanting to add booster to my ranchwagon as I've got 4 wheel discs and just a manual master cylinder.  It works good, but I'd like to take a little pedal pressure off it.

I've bought the aftermarket kit with the 8' dual booster and have the bell crank assembly.   The ratios are really off to be a bolt on to our cars.   We've tried the aftermarket booster on these cars before but they were never right feeling due to pedal ratio and the strange ratio on the bellcrank assembly.

I've found a mid seventies f100 bellcrank assembly might be a more suitable ration to work with stock pedal and yet still raise the booster up a little for clearance.

Yes I got it working and it works great.  Mine is drum both ends the booster for the disc's should be easy to find it was drum drum that wasn't.  Look up tomsclassic on eBay he had what I needed an makes the brackets to fit the 57.  The booster is 7" to clear manifolds on mine.

I seem to recall hearing someplace that you can use a dual diaphram booster for a 1970 Mustang.  Kinda makes sense because the big block mustangs did not have a lot of room to spare under the hood.

I bet NAPA, and RockAuto have pictures, and possibly dimensions on their websites.
