I have installed the large drums for the Rocky Mountain Brakes,and I am waiting for the rest of the gear to arrive (from the brake peddle back)- should come next week.
I have my rear wheels ready to install. However, I don't want to install them tomorrow and have to take them back off next week to install the RM brakes. The body is off the chassis, so I have good access.
My question is; will I need to remove the wheels to install the RM brakes if the drums are already installed?
Michael, yes you will need to remove the brake drums to drill some holes in the backing plate and install some bolts to mount the RM brake support apparatus. Noel
If you have original Rocky Mountain Brakes, you don't need to drill holes in anything!
These are Rocky mountain brakes that are coming from the mfg that distributes to the vendors ( I assume). Should I anticipate drilling any holes?
Anyone have directions they can post?
The RM Brakes made by Bud Williams do not need any holes drilled in the backing plate. However the drum do have to be removed to install a couple of bolts in existing holes. The instructions come with the brake assembly.
Michael, I just installed RM on my 1926 coupe with large drums. I bought them from Lang's about 3 months ago.
The instruction have you to replace the two bolts that hold the radius rod with two bolts that will allow the mounting of the RM mounting casting to the outside.
The two rear 1/4" rivets that hold the backing plate to the axle casting must be removed. I found that the rivet hole was really 3/16 so I had to drill out. Bolts are place in these holes and are use to hold two rear support brackets. I found that when the nuts and brackets are applied to these bolts that the grease cup is in the way and I replace with a Zerk fitting.
Hope this helps
Thanks Charlie..So there are no extra holes required in the drum - at least in the kit that you purchased? This is likely to be the same as mine.
Only on the 26-27 large drum rear axles do you need to drill out two rivits and replace with bolts. The earlier axles with small drums you only need to bolt on. Remove bolts and replace with the ones supplied in the kit.
Since your body is not on, do you plan to drive the car? If you only want a rolling chassis, you can leave out the axle keys and not torque the nuts. That way the wheels will be easy to remove.
