Re: Brake Booster Conversion

Ok here is my brake conversion so far! my original pictures I took as I went along are lost with that phone I had, so took these today.
I will post these in stages there is still a lot to be done yet...
On the firewall engine side I first started where the wires came thru the firewall and took out the rubber insulation that the wires go thru. Found center of that opening then going towards the passenger side edge of that opening staying at midway center. Measuring 3/4" out towards the passenger side on the firewall and then 3/4" down on the firewall then made that center of my booster shaft.
I then measured 2" up and down from that point and cut that out an inch wide opening allowing 4 inches for the booster shaft to move.
At this location it lines up real nice just about 3 inches away from the insdie steering shaft on the drivers side for the pedal arm..
( I used the Original pedal and swing mount looks good but not done I ran out of weld wire today but I do have pictures of that I will be posting soon.)
I then fabricated two 3/16" steel plates Cut out for the booster shaft swing openings, as well has the drilled holes for booster mounting bolts.
This is done for both inner and outer plates for both sides of the firewall, they are made as twins working together in a sandwich effect. Supporting the firewall along with more support that i will get to soon...
I went with a 10-3/4" dual brake booster and a 1-1/8" bore master cylinder ( bore may change to a 1" we will see if its too big of a bore ) I decided to use a 1977 GMC/Chevy truck brake booster and master cyinder. (Autozone bought)
I went with this because I wanted the booster to be away from the firewall for extra room back there for wires and I will be mounting a Trans dip stick that will mount to that booster mount as you can see the stick laying up by my level and this booster has the exstention bracket that gives me that space behind the booster.
I also have a combination valve that I mounted but I am going to remount that valve as an bottom master mount so I can reconfigure in my vent tube....
Here are some pictures of the engine firewall side with my engine I had redone....
Yes the booster clears from the hood hinge about 2-3 inches, I done all this with the hinge in the closed position
Post more soon..
