i have a brake fluid leak.looks like it's the proportioning valve.i just received a new one yesterday from kirban.as i was looking at it all last nite i noticed that it looks like the master is leaking.i saw brake fluid on the firewall but it could be from when i changed the accumulator bulb months ago.i didn't get that far into it last nite.brakes work fine just a small leak underneath.i am still going to change the proportioning valve but does anyone make a master rebuild kit?winter's coming so it would give me something else to do.
i checked kirban,gbody,nos4gn but can't find rebuild kit.or even just the master cylinder.

thanks

If it's a powermaster then no. No one that I know of makes one. If it's hydroboost or vacum then you should be able to get one.
