Well did another run at the brake situation this weekend. all new brakes on the back, new hardlines on the axle. Not able to bleed the brakes for s***. got a local mechanic that did house calls involved in helping with it. bled the entire system (again, and yet again for about 6 or 7 times) and the pedal still went to the floor. double checked the lines, no leaks. he double checked my install of everything, it all looked good. bled the master cylinder again, this is where he noticed that when I pumped the brakes, the fluid squirted out inside the reservoir instead of going down the brake lines. so it looks like my new Raybestos master cylinder is junk. And yes, it was bench bled before installation per manufacturers instructions.
At least the replacement of the new failed mastercylinder will be easy. Now to contact Raybestos and tell them their part is garbage but in such a way that they send me a new one...
