  Thinking about installing under the floor booster / brake assembly using disc/ drum combination....installed steering column and steering shaft and still welding on the top,,ready to move on to braking system...I was originally going to use booster , master cylinder and swing pedal from Metro Geo installed on firewall...  But needed to get some input what others are using
Chime in on what you are using weather on the firewall or under the floor  with your pro and cons and how it worked out for you during the install and if you are satisfied with the system you are using ...Thanks

you do not say exactly what car your needing the pedal and booster assembly for ????

I would look around ebay and see if anybody is offering a firewall mount ...UGLY , or an under floor mount assembly, kit.

The brake kit specialists offer the correct choices of ; small size double diaphragm booster, correct pedal ratio 7--1 , correct master cylinder for size and WEIGHT OF CAR , disc disc or disc drum proportioning valves, 2 or 10 pound residual check valves for under floor mount.

Just don't take something out of a car at the wreckers and transplant it into a street rod and hope it works, which a lot of times it will not.   Do you really want to cut $$$$ cost on something major like brakes ??????

You also need a motor that will produce 18--21 inches of vacuum at idle in order to operate that booster.   Radical camshafts will only produce 12--15" of vacuum and car will not stop worth a damn.   Stainless steel brakes corp makes a electric vacuum pump for this purpose

I'm building a 32 coach and I used a firewall mount master cylinder with a 7" dia. booster. I purchased a pedal assembly from Gearhead, which I had to modify the  pedal arm to clear the steering column not that big of a deal it saved a lot of work and fabrication. My master cylinder and booster is chrome to hide some of the ugly but with it mounted on the firewall it reduced the amount of hardware used. I have a 38 with it mount under the floor and that means a hole in the floor with a door or hatch to cover unless you are using a remote fill kit. I can post pictures of the firewall mount if you would like.  I have a plain 7"booster and master cylinder for sell if interested. :)

I used under the floor mount on mine as I wanted a smooth firewall.  There are a couple of pics in my build thread.  I can post some more specific ones in a few days if you'd like.

Give me a day or two to get you some pictures, I have the hood mocked up right now and I have it clamped in place.

Fatnlow  Here are the pictures of my master cylinder mounted on the firewall and my pedal assembly. I still need to do some more work on the pedal arm as it still is to close to the steering column.

Here's the pedal assembly, as you can the arm is directly above the steering column, I had to bend it to the right to clear.

62131...Thanks for the pics... Looks good on the firewall...  and  looks like bending  the pedal will work out really well.... Is that a Gearhead  Booster assy   ??

Sorry it took so long but here's a few pics.  These are the only early pics I had.  I bought mine through N.E. Rod Shop and I believe it was a Pete & Jakes.  This unit has a spacer where I can put a clutch pedal should I decide to change.  The key I found out is to get the pedal arm parallel to the floor and close to it.  This would mean the position of the assembly front to back.  If you don't get it right, as you pivot the pedal it needs a larger slot in the floor.  I hope that makes sense.  If not I can sketch something to clarify.

Yes it came as the complete kit.  I did have to grind the bracket a bit so the master cylinder would be parallel to the center line of the chassis.  I found another picture.
