its a n 18s 1952 and I can't get the front brakes to stop snatching, it seems that whenever I pull the lever and rock the bike the shoes stick and then if I brake they will snatch.

Yes there is an oil seal, part No. 014387, the Club have stock of them

Don't like the sound of the front brake, needs to be looked into, if your not confident yourself get someone to look at it for you.

Personally, I wouldn't ride it in that state.

Snatching sometimes occur if new linings have been fitted without chamfering the leading edge. Instead of picking up softly the brake will be an either/or brake, either full braking action or none at all. But it could be other trivial things like dust in drum or oil on the linings.

Keep them brakes braking or you may break something!

I wasn't over concerned with the grabbing, it was the sticking on that worried me, something definitely amiss there.

I have had brakes act like that when the linings are so worn that the rivets lose their hold. Also have seen thin linings break, causing pieces to wedge the drum.

In any case, follow previous advice & don't ride it until sorted out.

Cheers, Don.

Eagle, to answer your first post on this page,
...if you keep getting grease on your rear brake shoes, I would say that you have too much grease in the hub!!!
Todays modern wheel bearing greases should only require the bearing to be packed upon assembly and an occasional 'top up' smear when the wheel is removed for whatever reason.

Grease impregnated linings can cause grabbing as can loose front fork sliders. If you have excess rotation of the shoe activating cam it could possibly be not resetting its self when you release the brake! If the shoes are still servicable, you could fit spacers (packers) under the shoe expander pin, as described in your owners/workshop manual to remove excess movement.
