A Small Step Backwards…

August 6, 2021 – A small adjustment turned into a slightly larger project.

Moving the airplane in and out of the hangar, I’ve noticed that the brakes drag a little bit. I know this is an issue that has its fixes.

I decided to add springs to the master cylinder actuators on the pedals. On the first one I tried to do, the bolt attaching the top of the actuator was very tight going through the actuator. I decided to tap it out with my rivet gun. Of course I turned the pressure down. Well, when I did this, the welded tab on the pedal bent sideways. So I made the decision not to work this in the airplane, but to try to take the rudder pedal assembly out and do the work on the table. I had no idea if the assembly would even come out of the finished airplane, since it got installed very early on…

It does in fact come out… I had to disconnect the throttle cable at the quadrant.

Here’s the tab that bent…

I inspected it with a magnifying glass. Seems OK, so I pressed on with the rest of the work.

I installed the springs. They are 5/8″ x 3″ x .080″, by the way. I also put thread sealant on the fittings in the master cylinders. After my first engine run I noticed the tiniest bit of fluid seepage on a couple of the fittings.

The assembly actually slid back into place on the airplane a lot easier than when it came out. I still have to finish installing the bolts and connect the brake lines, then service the brakes again.

    Hi Pete
