Title: Rear brake backing plate question
Post by: Tom Murphy on April 18, 2011, 10:09:10 PM

I'm down to a few final parts on my HS restore, thanks to all the help from several great POG members. I've disassembled the rear brake assembly but have a problem with the cam. It is so tight that I can just barely budge it. Any suggestions on loosening this? Can I press this out? Wonder why this doesn't have a grease fitting like the front.

Yes it can be pressed out, I usually take it out at least a couple times a year and clean everything up. same thing on the front too. they just get crud in them. I use a wire brush for a gun cleaning kit to clean out the backing plate and some emeroy cloth to the cam, then a little grease and assemble.

Before I would press the cam shaft out of the hub, I would soak it for a couple of days with Kroil or equivalent. It should come out pretty easy after this treatment.

Not a bad idea to let it soak, I usually get in a rush to get it back together. besides. I don't like having wheels off my bike. so I usually remove the brake arm, hit it with some kroil, replace the nut to protect the threads and gently tap on it to remove it. It amazes me how seized it can get, especially if it has been sitting for a few months.. the first time I realized it was seized I was starting to panic and I thought for sure that I would have to replace the whole thing, fortunatly that was not the case.. just be careful and you will be fine.

Thanks guys, had it soaking all day, popped right out. Prepped and ready for paint! Thom, gun kit brushes are a staple in my shop, they work great for lots of applications, thanks a lot. Later, Tom

Another little tool that comes in handy is pipe cleaners. Use them lots for different things ans well as Military Spec q-tips with the long wood handle.
