need ideas for power brakes in a hotrod

I have a buddy who has a bobber style 41 chevy pickup..... Im suppose to do a conversion to power brakes for him..... so once i started doing some looking at the ubnderside of the truck i quickly noticced there was no way in hell i was going to be able to squeeze a booster and master cylinder between the ****** and the rails................

I had a thought of getting a chrome 2 res master cylinder, mounting it out front, on the firewall (scratch built firewall outta 18ga sheetmetal) and then mounting the booster to it but inside the cab...... from there modify a hangin/swinging pedal ***embly to make it all function..

I see no reason why any of this wouldnt work but im kinda looking to see if anyone else has a better idea

 

im pretty sure theres a conversion that pushes the booster / master back furtherdown the frame so it will fit

 

yep there is e gay item 270390724510 ****s probably made in china but what isnt

How about a hydro-booster? It runs off the power steering pump if you're using one. Way better than vacuum booster. Contact kapuron on here. He makes brackets, high pressure lines and such.

 

GM electric set up?...

 

Yep, the GM hydrobooster is a lot smaller than a vaccuum setup, not much more room than the master itself, it might put the M/C a tad further out though.

 

Don't know what your frame looks like anymore in that usta-be '42 Chevy but;
I have a '84 Mustang power booster and M/C between the frame and T350 Trans in my '40 GMC.
Fits with a busted knuckle to spare.
Frame is "stock" in that area.
Same as Chevy in that area unless yours isn't, it should fit.
I made the bracket to bolt to the side rail and through floor pedal.
Original pedal bracket bolted to the original transmission/bellhousing, as you know.

 

I had the same problem adding a booster to my T. I had to move the booster/MC back and operate it with a pushrod. Works good. The booster is a typical "street rod" type 7" and Corvette (1" bore) MC. I recommend a dual diaphram booster. I used a single and it's barely enough with 15" -16" of vacuum.

The pushrod is made out of 3/4" DOM tubing. I TIG welded a forged clevis on the pedal end and fabbed a threaded bushing (3/8" x 24) for the booster end.



This shot was taken with the frame upside down during construction.
