Peel back the rubber boot and determine if brake fluid is coming from 
*inside* the boot (i.e. leaking piston seals). Otherwise, it is not 
uncommon for a fair amount of brake fluid to have been spilt during 
installation and topping-off due to the awkward position under the low 
end of the bonnet, and it may be that this is what is dripping. If you 
don't see any sign of internal leakage, then clean everything thoroughly, 
lubricate the pedal pivot, and continue driving, checking frequently for 
more leakage and to ascertain its source.

You didn't say anything about brake ineffectiveness so I'm assuming 
everything is working OK.

If you do find leakage around the piston then it would seem you have a 
faulty rebuild; I don't see how you could damage this during installation.

Runs great, 
looks particularly bad since some SUV clown backed into it.
If you're near Mountain View, CA,
it's the red one with the silver bootlid.
