Aerodon Posted August 14, 2019 Report Share Posted August 14, 2019 I'm familiar with the requirements, anyone have the actual SB or Drawings for me? 1) Engine changes (minor) 2) Control counter weights (minor - bolt on) 3) Brakes themselves, easy enough to do, but fairly expensive. Changes from 30-56D single piston to 30-65 double piston brakes like the later Mooneys. 4) Gear doors - major cost of parts and labour. So I was looking at the Beringer wheels and brakes. They are quite compact, and might fit 201's, 231's, 252's without gear door modifications and then all the newer Mooneys that come standard with double piston brakes. If they were to be STC'd, I would say there would be a number of 252 owners who would commit. I realize that there would still have to be a 'deviation' from the gross weight increase instructions, but I would imaging that someone could get it right with a 337? I've started a discussion with Beringer, volunteered my plane for testing. Anyone else interested in helping with this idea? Aerodon Quote Link to comment Share on other sites More sharing options...
kortopates Posted August 14, 2019 Report Share Posted August 14, 2019 Don’t forget the expensive master cylinders and gear spindles - if go for it.The drawings should be available from any MSC. They are large foldouts - like the electrical schematics. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Why would you want a sexually transmitted disease in your mooney? i talked to berhinger at osh about 2 years ago. Great product. How much you figure it will cost.

Aerodon Posted August 15, 2019 Author Report Share Posted August 15, 2019 STD easily cured. A set of Beringers for an Archer are $6.5k including master cylinders and adaptors for the axles. Are the spindles changed for additional strength or to accommodate the brake hardware? Don 1 Quote Link to comment Share on other sites More sharing options...
kortopates Posted August 15, 2019 Report Share Posted August 15, 2019 Needed to accommodate the brakes torque plates. No difference in weight though. So otherwise identical.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
carusoam Posted August 15, 2019 Report Share Posted August 15, 2019 Don, The driving force for the dual piston breaks on the heavier 252 Mooney... was for more stopping power... cause the plane got heavier... which plane are you looking to put these on, and why?
