I have new brake cams and new levers. How are the pins secured when installing.

With a rivet gun and a bucking bar. Or you can have one person hold the cam from turning, and hold a bucking bar under the head of the rivet, while you use a hammer and punch to swage the buck tail of the rivet.


Rivet gun and sets:

I was able to squeeze my new brake lever pins tight with a pair of hefty vise-grips. :-)

Make sure the cams are in the right position of course before you install the pins and secure them.
Carefully tap in the pin until you have the same amount protruding from both sides of the lever.

Get a small steel block of some sort to use as a back up and brad down one side. Then place the block on the braded side and do the other side the same way. I used a small ball pen hammer brad to down the pin.

Take a torch heat ends of pins red and then using a dolly or ballpeen hammer as a back up, peen the heated end down with a second hammer. Flip over and do the other side. A process that is faster to do than to describe

Thanks for the helpful ideas. Not having the riveting tools I will try one of the other suggestions. I am curious about John Kuehn's comment. I think I have figured out how the cams should be positioned but am not sure. Is there someway to make sure. I know there is a left and right cam.

The brake arm should be angled to the rear of the car when its cam is horizontal, see attached pics that I took during installation of my AC brakes.

I just riveted a set of those two weeks ago. The new shafts are too tight in the bronze bushings. Had to ream one of the bushings.

Funny thing, that rear axle has AC brakes just like Mark's.

Thanks Mark, great pictures. They show it very clearly. I also intend to add AC brakes before I put the body back on.
