Hi all,
Does anybody know the best way to remove the peened over pin that holds the brake cam on? I've tried drilling, hammering, heat, and using my 20 ton press to no avail.
What's the secret???
Thanks,
John

Hi John,
I'm assuming you are wanting to replace the cams & bushings? You have exhausted the usual methods, sometime the pins are so rusted that they
just will not come out. I sometimes use taper pins & they will not come out the wrong way! Just mite be easier to to replace the levers with
one's that came off easier, than fighting the ones you have. Just cut the shaft with a hack saw & hope the bushings are more cooperative. Didn't someone sell a lot of those levers earlier this year? Sorry that is of little help.

I was wondering if you were working on the cam on the handbrake cross member. It has just one pin. It is also usually bronzed to the shaft.

The levers on the cams at the backing plate have two rivets each side. I drill the rivets three parts of the way through. I use a larger drill to make the hole cut the side of the rivet. Then A pin punch resting at the bottom of the hole will usually dislodge the rivet. A second pair of hands to hold a heavy hammed under the other side will make the process easier.

Hope this helps.

When I replace a brake cam I cut off the cam chuck the stub and lever in the lathe and bore it out.
A lot easier on the brake arm. If you don’t have a lathe make a new friend. I have more friends due to tools.

One pin so your working with a large drum rear axle brake cam?
I cut the peened head with a sharp cutting chisel, then drill with an undersized bit, then support edge of cam arm on an anvil and punch it out. Bigger hammer if needed.
Example photos from recent effort on a small drum cam (two pins). It’s much harder if axle is on the car.
