I am working a on a set of drop brackets for the rear end of my 1926 speedster. They will preclude the use of the mounting plate for Rocky Mountain Brakes, so I want to build them to include a mounting pin to take the bands for the Rocky mountain set up. Not having a set, I need to know the spacing from the center of the pin where the band and activating lever mount to the outside of the drum. I would appreciate if someone could send me that measurement. Thanks.
Are you talking about mounting a set of period original RM brakes, or the current reproductions? The mounting methods are completely different. Here is an ad showing what the period originals look like, the brake band is anchored at its midpoint, towards the rear of the car:
Here is a picture of the current reproductions available from the vendors, the brake band is anchored at one end, towards the front of the car:
Can you pull the back wheels off as easily with Rocky Mountain brakes or is it more complicated
You can pull the wheel off with any outside brake setup. You might have to back off the adjustment to get it back on but that's about it.
The reproductions please. They fit my bracket design better.
I just went out and looked at a set of 26/27 that I am working on. It's approx 1 inch. You can go a little more as the part that holds the band is a "U" shaped loop. The loop is tall enough that there is more then enough room for take up for worn linings.
Note that the ad above shows the later Tractor Train brakes, which are a little different than the earlier version manufactured by Rocky Mountain Steel Products.
Great, thanks for the measurement Mark.
