Brake guys, a quick question please, I hate brakes! Options

I'm bleeding my brakes and find a leak in one of the rear calipers right at the adjuster screw on the outer piston. I pull the caliper off and take it apart and find that there is no o-ring, gasket or other means of sealing the adjuster screw. It's simply a metal to metal fit and I can't imagine that that's enough to seal.

I've got a rebuild kit and there isn't a seal included for that adjuster screw. There is one for the other piston. So what am I missing here? Is there supposed to be an o-ring or something else to seal that screw? Thanks.

OK, here's some pics of the adjuster screw in question.


There's a boss machined into the caliper body where the flange of the screw goes (2nd picture), but there is not a recess for an o-ring. You could put an o-ring in there but it would simply smash down and be destroyed as soon as you tightened the screw down. I don't see any other sealing method. It's not like the o-ring setup on the inner side of the caliper.


I'm going to cut a gasket to fit the boss and put it all back together again with a very tight locking screw. I'll check back tonight and let you know how it goes and listen to all the suggestions as to how I REALLY should have done it. (IMG:style_emoticons/default/headbang.gif) Thanks guys.
