The Skyport master cylinder is a good fit for either Goodyear or Cleveland brakes. It will not work with the Hayes/Goodrich brakes found on planes sn 812 and below with 4" wheels.
While Skyport is here to sell you parts, I do have to agree, if it ain't broke... (Spend the money on something else you need that we sell...) ;) -- John Skyport East www.skyportservices.net
