Seeing you mount those cylinders brings back memories of building a race car and finding a perfect ready made racing pedal box assembly in a Reliant Robin of all cars
I'm a bit of a hoarder when it comes to metal. Outback I have a couple of piles of various metal objects, from basketball hoop stands to building siding.
I'm always seeing metal use in everything. Especially curved pieces.
Like my windshield frame is made from lawn chair frames.

here is the master cylinder
located in El Monte Cal.
That's the same master cylinder I have. There are 3 ports on each one, but I will be plugging up one port on each cylinder.
I'm also removing 'one' brake light switch, as it interferes with the mounting of them side by side.

One cylinder will be for the front brakes and the other for the rear brakes.

What was the problem with the one that didn't work?

After a couple of tries, this is what I ended up with.
It's still in the rough stage, but it fits.



Now I'm working on the actuator arm design



Still need to cut off the 45-degree angle on the top of one upright.



Fitting as designed



The bracket came with an angle that was near perfect to the angle of the frame.
Thus keeping the fluid cups level.



I think I will not use the actuator arm I have. After seeing this part of the install,
I think a less bulky, possibly adjustable shaft will be better.

I could not get the unit to pump any pressure. Hopefully you have better luck
I used mineral oil. Absorbs less moisture than brake fluid.
Suggest obtaining a large syringe from local pharmacy then reverse bleed your brakes.

Thanks for that tip. I may have a go at that.

This morning I got the actuator shaft installed and the holes through the frame drilled out.




But I've run out of useable shaft collars so ordered some more.
I need one more for locking the shaft in place and at least two more for the actuator arms.
Using this method allows for the removal of the shaft...for whatever.

The only thing that bothers me about using shaft collars to lock the actuator arms, and still allow for adjustments is the possibility of slippage from being foot operated. There will be a lot of torque placed on those set screws. If I drill out seating holes or file a flat spot, that eliminates the ability to make adjustments.

The brake actuator is done and tested.





Welded to tabs onto the bracket that came with the MC.





Using 3/8" shoulder bolt

Finally got 'undepressed' long enough to work on the brake foot lever.

From an old Gannon fork tine, back when I had a garden tractor.


Cut angled welded drilled and semi ground smooth.
Still have cosmetic holes to drill out and trim to length.



Trial fit of mounting hardware



Trial fit onto the frame



Just room enough to fit next to the steering box.
Need to trim off about a 1/4" off the end of the shaft.



The brake lever will pivot on the shaft
Temporary scrap aluminum connecting bar. It works as intended. Just need to make another/final connecting bar.



The shaft collars are welded to the frame and the 3/4" shaft is secured with the set screws.



Haven't decided on a foot 'pad' or 'peg'. I think I need to try and be symmetrical with the throttle pedal.
So a flat plate design may be forthcoming, that will mirror each other on the two functions.

The peg version...maybe.




This is sorta what I'm thinking of doing.

Haven't been gone...just set on pause.😴
This election thing has really taken a toll on me.
But it's coming to a satisfactory end, so I'm beginning to relax a little.
But that's a subject best not discussed here.

The weather in the last couple of days has been super.
I have been energized to get out in the shop and work on something, anything.

I chose to make the hubs for mounting the rear brake discs, and here is some progress.

But first

When your cutting discs get too small do you throw them out?
If so, you're missing out on two uses for them.

The smaller ones work great for making those really small tight curving cuts.
They are also useful as a template for all sorts of circle sizes.
I'm thinking of marking a select number of sizes and putting them away until needed.



4" circle being used here.



I'm using a 3/16" plate (4.78mm)
3/4" center for axle.



Marking outer diameter for each mounting hole.



All that remains is to weld on the shaft collars. I think one on each side of the hub. Two set screws being better than one.

That's a great looking project there. Are you still on AZ? Did you finish this?
It puts me in mind of the Munsters mobile.[/QUOTE]

Thanks, Hukah

No, it's not finished, just in limbo for now. The latest work being the fabrication of brake disc hubs.
The Munster Koach is one of my inspirations.

The weather has been quite cold and damp for this old man, so heating the shop for working only a short period isn't economical.
In fact, it rained last night with a dusting of snow. Snow is forecast for tonight (Sun) as well and again Wed-Fri.

We just had our 25-year-old carpet replaced last Thursday. That meant emptying the house of all nick-nacks, and furniture. No easy task at our age. We're still putting things back.

Maybe I'll get going again as the weather warms up.
