can the caliper sieze up and you can still bleed it. when i press on the pedal it does down but it dont stop the bike at all

 

The easiest way to see if it is seized is to take the caliper off and try to manually push it back in. It may be seized on the return. But if the piston moves out when you press the brake and you can return it with pressure then I would assume it is functioning properly. The rear brakes are not the best on these but they should stop the bike at slow speed

 

ok well maybe i didnt make it clean to understand not saying it in a mean way but when i push the brake it doesnt do anytihng it dont move at all there is fluid and i bleeded it and still nothing

 

So the pedal is firm when you press it, but there is no movement at all of the caliper piston?

 

yep there we go and on top of that yesterday i was riding down the highway with my wife on the bike and i see alot of smoke and i noticed it coming from the back i pulled over and saw oil all over the carbs and in the motor it happened before a week ago but it was alittle and i just thought it was engine breather hose but i guess not what can cause that to happen

 

Ok, in the case of your brakes, yes it can be seized and you still be able to bleed it, my apologies, I misunderstood your first post. You can bleed it, obviously, because the bleeder is before the piston, if that makes sense. After bleeding, if its not moving, and you are sure all air is out, then a seized piston would be my diagnosis too.

 

Ok, so it does sound like your piston is seized... time to rebuild that caliper, which is no real big deal, once you get the piston freed up.

As far as the other issue - it's better not to tack on additional problems to a thread started for something completely different - what I mean is, you'd be better served with starting another thread for the oil issue, and titling it appropriately... you'll need to give some more information as well, as oil being all over the place is a little vague.
