I dont have any trouble bleeding brakes on the big truck without the presurre bleeder. Take any tank thats air tight and has an opening to put the brake fluid in. An old freon tank works great, Put a rubber hose from the tank to the cap on the master. The cap should have a hose barb threaded into it. Put the tank with the brake fluid on your seat or hang it up from the roof. Gravity is your friend here, just open a bleeder some where and the fliud will flow. This will work on any system old or new, you just have to have the tank higher than the master and keep fluid in it.
