Does anyone have photographs of original Rock Mountain Brakes? The Complete Set? Every last piece?

Larry Smith posted a pic of original clamp back in 2016. Looks like it would be easy to make, I would suggest using an aircraft eye bolt from aircraft spruce. You may have to extend the threads further on shank, just an idea.

These fixture bolts are an even closer match

Here's another photo - Ed has a great suggestion !

Swing Bolts

Those hinge pin swing bolts are very close, but need to be modified to be correct.

This isn't a "photograph of an Rock Mountain Brake 'pedal clamp'!

[Original Smith]

It certainly is!

Found One.
Now I just need the C clamp.

The C clamp looks like it would be easy to fabricate.

C-clamp material - 3/16 x 3/4 flat stock w/rounded edges - Mc Master-Carr.

Here's a picture of the one I made to use on my AC Brakes...

[speedytinc]

The pedal linkage unit appears to be unused. mounts to pivot from the DS tube.
Pedal clamp is 2 pieces cast to clamp onto pedal with 1/4" bolts.
Drums are riveted together.
Obviously made for a cable that automatically equalizes.
I dont know if this is an original RM brand set or a Sunderland reproduction.

[RajoRacer]

John - I have a set of both - the main bracket you are showing is an original. The Sunderland drums are cast in one piece.

[Original Smith]

I'll stick with the original design.

When Eaton took over the production of Rocky Mountain products, they made a number of changes, some good, some not so good.

Larry,
What is the “original design” that you referred to?

Would you be able to provide more information or “photographs”.

Those following this thread would benefit from more elaboration.

My "modern" Rocky Mountain brakes have rods with the associated equalizer. If I were to convert "back" to cables, two questions:

Did the originals interact with the parking brake, and if so, how? Or since I already have the equalizer installed and linked to the brake pedal and parking brake, should I just replace the bracket that the brake rods attach to with something (see next question) to pull the cables?

I've recently seen pics posted showing a "y-shaped" channel to pull the brake cables, and others show a pulley to do the same. The pulley seems like it would be better for equalization. Which method was used with the original set-up?

Keep crankin',

Originals are not integrated with the parking brakes.

I have seen the pulley setup before. I believe it was original. The u piece on my setup is new to me, but I believe it will work equally well.
That piece is the same all of the parking brake setups for 60's fords & probably many others used. Both these pieces provide simple & cheap self equalization.
