Stop the plane I want to get off.

>From the very beginning of the test flying the original brakes gave us problems. They overheated and failed a couple of time and were replaced once in the first 10 hours. When I finally got the time flown off and started expanding the envelope they wore out quickly. It got to the point that I could not hold position on run up. That is when I changed to the "Grove" brakes and they are better that the originals ever were. On top of that I can now change pads without removing the wheels.

Last year, I had to use at least 200 lbs of brake peddle to stop my plane. I couldn't hold the plane for run up. I talked to Matco and they told me that because my plane had been sitting for a few months, I might have to "reseat" the pads. I taxied the plane for 1/4 mile at 1,500 rpm and 5 mph then I sat for 15 minutes and let the pads cool. I did this 4 times as recommended. The brakes worked better after that but got bad again within a couple of days.
I purchased black Cleveland pads and new disks from Kit Components. I can now lock my wheels whenever I want with just the right amount of peddle pressure.
I may still go with the Grove wheels (http://www.groveaircraft.com/) because they don't have to be tightened like the Matco's do. This will give less wear on landing. I also like the idea of having the brake pads wear symmetrically because of the dual piston calipers.
