I've found after 700 hours that my Cleveland Brakes Master Cylinder may need a little attention. The brakes are a little softer than I like and at times (not always) have a little problem with taxi. The model is 10-88, however the Illustrated Parts List also show this listed as 10-49, 10-50, 10-54, 10-54a, 10-55, 10-55a, 10-55b and of course 10-88. I don't know the difference, if any between the different models.

I'm looking to purchase a couple of Repair Kits, Part #199-516 but can't seem to find them. Does anyone on the forum have a suggestion of who to contact for the kits?
