Don't think so. Pressure in a single master cylinder brake system
should be (almost) equal at any point in the system. Especially
after a few milliseconds of constant pedal pressure. Sure the
fluid leak needs to be repaired, but I'll bet fixing it doesn't
resolve your pulling problem.
My previous statement was based on fluid leaking onto the
brake shoe surface.

Bill, the brake that is leaking is the front left brake. It seams to be
leaking right where the flexible line connects to the steel one. I replaced
the flexible line, but I think it is still leaking. The truck is pulling to
that side. Is it possible that because the left brake is closer to the
cylinder that it is getting what fluid there is and is working better than
the right one? Give me any thoughts you might have on this one.
