    Brake pedal hitting costs tube

    I have both master cylinders installed — Mark IV complete kit. Wildwood pedal assembly. The brake pedal when the pressure is off hits the the cross tube. I have tried threading the push rods in and out, but I’d doesn’t seem to make a difference. I do not see any other way to adjust. Thoughts?

    That is how you adjust them. By threading the push rod in/out of the clevis attached to the pedal arm. There's a spring and retaining ring in the master cylinders that force them all the way out to a fixed location. In this position, the pedal must stop short of the frame cross piece. Otherwise the master cylinder will not work correctly. Sometimes it's necessary to trim a little off the end of the pushrod so that it goes in far enough. I believe that's mentioned in the instructions.

    Thanks! I’m going to have to cut the push rods. Pedal still hits when fully threaded. I’ve seen some other comments where the issue solved after removing 1/2 in. From push rod.
