Cleveland Brake Master Cylinders

[N925JL]

I have an RV6 with Cleveland Brake Master Cylinders (10-30). The Van's catalog currently has replacement master cylinders in their catalog that appear to be made by Matco, offered for the RV-6. Does anyone know if the Matco Master Cylinders offered by Van's are a direct replacement for the Cleveland Master Cylinders i currently have?

IF your Cleveland Brake Master Cylinders are leaking, new O-Rings can be had for a very small around that would be less than 10% the cost of new Matco. IF you want to add dual brakes, yes the Matco could be used on the other side. Neighbor that had an RV-6A had Cleveland on one side and Matco on the other. I could not tell the difference in brake operation during taxi on either side.

Not sure what year but Van's changed to the Matco master cylinders because the cost of the Cleveland were a lot more money and in my option not any better than the lower cost Matco.

In my opinion, the Matco that Van now sells could be used to replace a damaged Cleveland that cannot be repaired.

I have the same Cleveland 10-30 that you reference in my RV-6. They are most likely three decades old and have had O-Rings replaced numerous times. I did post a PDF of the mil spec part numbers that Cleveland published along with the Cleveland part numbers in an old thread. The Mil Spec O-Ring part numbers are a fraction of the price of the Cleveland part numbers and are the same item. I can did up the document and post it again if a search does not find it.

Edit: Adding the PDF for 10-30 parts list and diagram.

Thanks Carl. I have a rebuild kit for the cleveland, but just a bit intimidated by the small parts. Want to make sure i have a backup plan in case i mess it up.

I have some leaking 10-30 MCs . Do I need the overhaul kit or is it likely that the o-rings are good enough ?

When I rebuilt mine I only replaced the o rings. Its a good idea to polish the piston rod with very fine grit emory paper to remove any fine scratches. Sorry I don’t recall exact grit. Seems some leak after new rings due to very fine scratches on the rod. Gary, you have a recommendation on grit?

You won't mess it up, pretty straight forward.

Keep the Cleveland stuff. Simple and cheap o rings is all you need if leaking. Corrosion is what kills them

I only use Scotch-Brite pads on mine. Been rebuilt three times so far with only mil spec O-Rings being replaced.
