Someone, I think Emery correctly stated early on that constant pressure could cause leaks. That is true but there is more.
Do NOT NOT NOT, use the screw adjuster to crank down past where you normally hold the brake to hold on whatever slope you are on. To do so put much more than normal pressure on the hydraulics. Ask me how I know this.....
Rob Mueller made one just like V2.0 and was cranking the handle down tight when he noticed the pedal went down suddenly. Didn't think much about it but later he wanted me to drive his coach and see how good the brakes were. As I was leaving my house, I said, "NO BRAKES" as I was standing on the pedal.
Turns out we literally blew one of his braided stainless brake lines out of the fittings AND KILLED the master cylinder.
Rob's brakes have been on the coach for several years but the moral of this story is that you only have to move the pedal the the same point you'd be at if you were holding the brake with your foot. Any more is just excessive pressure and BAD THINGS CAN HAPPEN. In Rob's case, a STOMP ON THE BRAKES PANIC STOP could have done the same thing....or not.
The good news is that the local Advance had a new brake line (not braided) and I had a brand new P30 MC. He also had a Hupy bleeder top and we're cobbling up the rest of the pressure bleeder and they should be good to go tomorrow.
DON'T PRESS IT DOWN MORE THAN YOU WOULD WITH YOUR FOOT UNLESS YOU WANT TO TEST YOUR COMPONENTS TO POSSIBLE FAILURE.
