I have a Kitfox II and the right brake master cylinder began to go soft and eventually fluid began coming out the top of the cylinder near where the snap ring opens. I have been trying to identify the origin of these brakes but no one has been able to identify them. I even asked a Matco rep. if he knew; he did not. I would like to find a replacement but may be forced to consider replacing both with new cylinders. I am considering the Matco MCMC-5, however the length of the current cylider is 6.5" and the Matco is 7.7". I'm certain I will have some rudder pedal attachment issues if I swap them out. Anyone have any thoughts on this?
