Hi All,

I have just built a 7 SS and I find that I am now flying in and out of very short sandy strips. I have the Grove brake kit 65-211 that came as standard from Kitfox, and I have bled the brakes and worn the pads in with about 10 hours of circuits at my local airstrip. Despite this, I find that the braking is not as sharp and effective as I would like it to be despite hard braking and pressure on the pedals. My pedals are firm on braking and the brakes get hot and make noise, but it still wont slow down fast enough. There is no skidding either. My brakes are strong enough to hold the plane on full throttle run ups, so they must be working. I think I just need extra braking force on landing.

I would like to upgrade the brakes to the Grove 66-152 series that have bigger callipers and discs and more braking force. I presume I can leave the master cylinders and piping the same and that I would just need to change my axles from 1.25" to the 1.5" ones made by Grove, and then swap over the tyres to the new wheels and do the fitting?

Is this a straightforward job and does anyone have any experience with changing their axles from 1.25" to 1.5" ?

Is there anything else I can do to make my braking sharper and more effective ?

Thanks in advance for your replies
