    I believe that is what this is? have a small leak right where the arrow is pointing. have it temporarily clogged. Is the thing a whole assembly or can i get a hold of the part that looks like a brass fitting?

    They'd probably give you 10 combination valves at the wrecking yard for $10. No one ever takes those things, and they rarely fail (yours is the first or second I've ever heard of leaking) so it would be just as easy/cheap to go get a couple used spares.

    yeah its odd, i thought at first it was just a loose nut, but the more i feel around it has a hole in the damn thing. on the top of the brass fitting none the less, *** wonders how it got there ***

    <font color="green"> Mine leaks from the same place. I'd replace it but all the lines are frozen in it so I'd have to cut them all and replace them. Too much work! It leaks reeeaaaal slow so I'm not worrying about it right now.</font color>

    Go to a junk yard and get one there for a buck or two. The one thing that you have to watch is they are not all the same. Some have the proportioning setup more for the front or rear than others so try to get one off the same type of vehicle unless you want to try something different in your braking system such as using more rear than front brakes or vise versa.

    <font color="green"> Rob, how often are you having to top it off? If I drive it every day then I need to add a little fluid after about 2 weeks. Is your faster than that? </font color>
