Installing Brake hub

I need some help. I'm not getting the brake hub to seat correctly into the wheel. It looks simple but there's something that I'm obviously overlooking. As a result, I've got no rear brakes.

Re: Installing Brake hub

Hi Jay, is it the brake shoe's that is holding the hub off , could be the shoes are not sitting on the brake cam properly, try turning the brake shoes and brake hub as you push it into the wheel, take it its the crf50

Re: Installing Brake hub

What is meant by turning the shoes? I took the hub off another wheel to put on this wheel and now it won’t seat on either. Yes CRF50. I’ve rotated the hub 1080* already, tried pressing down and tapping lightly with a mallet.

Re: Installing Brake hub

You can put the brake panel in the hub, but it sticks out too far?

Or you can’t put the panel in the hub at all?

Or you can’t align the panel up with the protrusion on the swing arm?

Re: Installing Brake hub

The brake panel fits in the hub. There’s a lip around the end and the panel fits neatly around the hub taking out the slop. When I put the panel in place it doesn’t go far enough for the lip to close; a couple millimeters is all I need. I tried installing the wheel and I get no brake contact to the inner hub at normal deflection of the lever. Adjustment doesn’t resolve.

Is there an extra spacer you’re not accounting for? Sounds like the shoe panel is bottoming out on the hub bearing.

Or the hub is a mismatch for the shoe panel.

Oh, and what Bill was asking was spinning the shoe panel while manipulating the brake arm to see if the shoes are the problem. But if you have no grab on the shoes to the drum then that’s probably not it.

If you take the shoes off does the panel fit farther in the drum hub?

Re: Installing Brake hub

The panel is OE. I took it off the OE wheel to fit it to my aftermarket set. When I had a problem I went back to the OE wheel and got the same condition. No spacers were harmed in the fitting of either wheel.

After I’m done resolving a problem on the 110 then I’ll go back to solving this panel issue. I’m also allowing time for my post to be read. It nearly 1:30a and it’s time to reassemble the 110 - had to do some grinding :-) no pun.

Re: Installing Brake hub

I took it to the shop. Giving benefit of doubt they determined that the fit of the hub is fine but the no brake problem was because of a worn cam. They added a shin and lightened my pocket by $40.

Re: Installing Brake hub

After the event I needed to switch back to dirt mode. OE hub fit so tight the brakes were locked. A few turns on the adjuster and it freed up enough to run but I suspect some pressure on it still. I may have to buy 2 new hubs as I’m sure the OE hub has some wear and the aftermarket is a few mm too big. Next time I swap (next week) I’ll measure the ID. Grrrrrr....more $$$$
