Weekend Update:
Task: Under dash, 90 degree mount, master cylinder & pedal linkage.
The idea of running an exposed master, traditional fire wall mounted master cylinder on a fenderless build didn't appeal to me on a few levels. First was the aesthetic component and second was the vulnerability of the exposed MC. What if I hit a chunk of tire, or something, going down the road and it flew up and took out a break line, etc. Just was not comfortable with it. So I decided to "hide" it.
Started off with a basic, $15, Full-size Ford, dual drum master cylinder from the local O'Reilly. Add bracket ideas.
Backing/firewall plate is 1/8" steel - all mounting tabs are 1/4" steel.
Add in side gussets for support & a center pivot point for the bell crank.
Add some holes for fun . The bell crank & pivot is shown in the center.
This is where I made a slight after thought change. I didn't care for the hoop on the end of the master cylinder rod, so I cut it off and threaded the rod and screwed on a spherical rod end. The rod end is a bit thicker than the original hoop end (which I measured around) and it raised my rod angle just a tad. I don't think it will matter though as it has plenty of clearance in the piston bore on the MC. But if anyone knows for SURE, please let me know.
Botled on the inside firewall, under the dash. And yes, there is ample room to access the top of the master cylinder.
I made the brake pedal, linkage & brake pad also. The sheet metal floor shown is just temporary. It's actually an old cookie sheet - LoL.
The brake pedal has additional bends in it to clear the future horizontal steering shaft that will exit the side of the cowl for cowl steering.
Another view:
And the home made "antique" brake pedal... It's a 3" diameter cut from a hole saw. I then used smaller, alternating, hole saws to cut in the inset grooves.
