Front brakes are completed

I ordered brake lines recently and mounted them up.  I was *really* nervous that I had measured incorrectly and either ordered them way too long or way too short.  It seems I measured them perfectly.  SS with a clear plastic sleeve.  The master cylinder allows a long travel on the brake lever, which is good; I'm worried that these brakes might be too much for such a light, rear-biased bike with a lot of rake...locking the wheel at speed would be...ungood.  If I find that they're too much, I'll remove a rotor and caliper and get a new master cylinder that is designed for a single caliper; this one locks a single WAY too easily.
