Adjustable brake pushrod..what did I do wrong

Plenty of people use Dr Diff's adjustable master push rod. I doubt that's the problem. Do you have the stock shoulder bolt? If so, compare the shoulder length with the width of that heim joint. I bet they're pretty close.

I'd maybe try lengthening the push rod so the angle isn't as drastic (w/ the pushrod on the correct side of course).
