The O-rings on that fuel inlet tube will likely leak if there's a lot of movement. Mine leaks when it drys out (like when I turn the fuel off and the bike sits for a few weeks) but they seem to swell up and seal once fuel hits them.

If the bike sat long enough for the brake to freeze like that then I imagine you'll need to rebuild those carbs so get a complete set of O-rings for the fuel rail and split the rack. There's a guy on the DOHC forum who sells O-ring sets http://cb750c.com/modules.php?name=Forums&file=viewtopic&t=13525.
(you'll need to join the site to see the post I think). I got a set from him. I haven't bothered to put them in yet because I think fire under my ass is cool and I'm an idiot.

P.S. You'll want to read this carb cleaning manual too - http://www.cb750c.com/modules.php?name=Forums&file=viewtopic&t=13611
