Go get a mity-vac or even the harbor freight knock off version of one and use it to bleed your brakes. You'll never have to have someone in the cab pumping them again. Remove the bleeder screw, put a little teflon tape over the bleeder screw threads, snug it down, attach the hose to the bleeder screw, the hose to the catch can they come with, and another hose between the can and the vacuum pump. Pull a vacuum and crack the bleeder. Simple as that. The teflon tape helps to prevent air from being pulled past the bleeder screw threads.
