Its probably down and locked e brake system with bvm name. If so yes it is as stated down and locked said they would be showing the new e brake system at joe nall this year.
No, the BVM E-brake system is just a powerful servo pushing on a cylinder to give you hydraulic pressure for hydraulic brakes. That method was originally developed by Bob Fiorenze for his EDF and DF aircraft a long time ago. Since he works at BVM now, I'm sure he was involved in adapting it to BVM brakes for them.
