Hello,
i am from Austria and have a RHD 1916 T Towncar. As Austria is a country with many mountains i am installing RMB but have run into a problem with the Brake pedal. I have had the additional part welded to the brake pedal as suggested. But now i have a problem as there is not enough space for the clutch and the brake to move free. Can someone of the RHD drive world help me and give me clue where this part should be located to give free move to both.
The hogshead has EXP cast on top. I hope you can see the problem in the picture.
Thank you for your help.

A side picture would help better but appears the add on lever is welded a little to far back, just from what I can see. Recheck the instructions, but you should be able to remove it, Heat it up with a torch and bend it forward.

Hope this Helps,

Hank

The brake shaft moves to the left so the answer is to change the welded on lever to a position on the left side of the clutch lever.
I also have a separate transmission brake pedal so made a new pedal shaft which is longer.

Here is a photo of my RMB set up, the RMB lever welded on the pedal is stepped over to the left.
It only has to move back and forward, the separate trans brake can move left separately.
With this set up I was able to eliminate the poor rear braking of the RMB.

I see now said the blind man. You might want to find an offset clevis, should cure the problem.

Thank you for your help. I attach a picture with a side view.
had made another mistake, too. As the lever acting the clutch from the handbrake segment to the clutch pedal was sloppy a fabricated a bush on the pedal and now it can't compensate for the side movement of the catch pedal. I am not sure if this link is fed into he pedal the right way ( see picture) or should it the way around?
Best Wishes.

Thomas, there has to be some slack so the low speed pedal can move sideways, so it may have been OK before you bushed it.
Mine is the same way as you have your clutch link.
Here is a photo which shows a bit clearer how my RMB welded on lever is attached to the brake pedal.
Also the lever for the brake to connect to on the RMB yoke which pivots on the hand brake cross shaft
I made also with a bend to the left to get it away from the clutch mechanism.

Thank you for your input.There is just one Question: How is the top end of this setup? 2 brakepedals?
Another idea i have is to extend the brake shaft to the right side and use the right hand set up of the RMB?
What do this of this idea?

Yes, there are two pedals. I only had to use a longer shaft for the pedals which can be easily returned to original when needed.
I set the brakes up to work separately, to get both transmission and RMB to work together is difficult if not impossible to adjust so they both work for long before they get out of adjustment.
The amount of travel and pressure needed for each brake is so different. Some people think that if you set the RMB to work first and the transmission brake to come into action when the pedal is pushed harder then you have both brakes. I'm sure that would work for a short time, but with two different brake linings (soft band material and hard RMB) it has to loose the adjustment fairly quickly.
I intended driving my T on 3 month long trips and did not want to have to spend time adjusting the brakes as I could see they would quickly loose the adjustment and I would not know if I was getting results from the RMB or the transmission. If they are separate each can be adjusted independently.
In 15,000 Kms I only adjusted the RMB once, the transmission brake still hasn't needed to be adjusted nine years later and don't forget the RMB don't work well if going backwoods. There has been lots of accidents where drivers had to stop on a hill and the T had no brakes when it rolled back, not the best time to find thee transmission brake was not working.

Another option is to set the RMB up so a lever is used to apply them. That way the transmission brake will work as intended and the RMB can be applied as needed. That method also works great as in hilly country you just use the lever to slow the T and the foot brake does not need to be used.

What you have with RHD and the Rocky Mountain Brakes is a design that was only made for LHD, so you have to work with the parts and make them work for you. A mock set up to work on the mechanism would be best as it looks like you still have the hogs head off the motor.

Not sure what your idea about the right side for the RMB entails, do you mean putting the connection for the RMB to the right of the clutch cam on the handbrake shaft?
Here is a photo of the my pedals.

Hello Luxford, thank you for the picture, clever solution.
I meant to go with a new shaft through the hogshead and have the usual left hand design of the RMB but i think the shaft will be too thin for the force applied to it.
I seem to have some problems with left and right so i apologize for the confusion.
Thank you

Bit disappointing that no one else has bothered to help Thomas here.
Being in Austria with a Model T Ford probably means that local help may not be available to him.
Here is another set up which is for a Rocky Mountain Brake type system but has been built from scratch.
The cross shaft is pivoted from the right side of the clutch cam on the hand brake cross shaft.

Hallo Luxford,
thank you again for your help and the pictures.
Another interesting solution.
Hope you got my email.
Best Wishes
Thomas

NO, I didn't get an email,
Seems that feature of this Forum system does not work so well.
