Update: took the pickup back to them, they fixed it, the owner was very apologetic. I offered to pay for the parts and let him cover the labor, but he insisted on covering it all.
Though there is not much chance of any of you guys using him, I will give the info, since the rest of his work was good and he took care of this.
He replaced the leaking master cylinder and lines from it (hydra-boost) to the power steering pump, as well as rear brakes, in the original job
