Brake Master Cylinder mounting question


 

First, a bit of back story, I did not build this airframe.. it was started in 80's and ?90's. I took over this project from Jim Howell.. I only have a photo album full of actual pictures of the original build..otherwise we're trying to finish this airplane without much info.

I bought Matco MC5 and am trying to set them up and the brake geometry has got us scratching?our heads. The lower tabs anre not exactly welded straight, not sure if there was a reason as to why, or perhaps trying to match the build of the pedals. Toe brakes have the upper arms welded on top of the
pedals (Unlike what JC has said to weld them lower on the upper toe brake parts) which add to the angle being wrong..?

I am trying to figure out if I should just rebuild the lower mounting tabs to lower the MC's all together to get the angles right? Here are some pictures. One pic from the original builder as he was testing them out, but I cant think that taxi'ing around would also actuate the brakes based on the location and the angle of the MC's.?

I also can have Matco swap out the shafts to their shorter shafts which *I THINK* would achieve the same effect as lowering the lower mounting points??

Any thoughts, other pics, suggestions, advice highly appreciated!
