Does anyone have any experience with the BVM E Brake? It looks like a handy but of kit to eliminate air systems completely from our gear systems (when used with electric retracts).

I assume that it isn't proportional (or is it)? Will it work with disc and o-ring brakes?

The price is ok when compared with something like a UP-6 or Smoothstop.

It works with his (bvm) brakes so one would assume it works with any o-ring type system?? it looks proportional too.

Vin...

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.

All i can say is Bob Fiorenze Doesn't work at BVM as far as i no. I was down there for a week and a half working for Bv during FL jets and not once did i see Bob F at the shop.

The "new" E brake is a refined brake system that BVM sold back in the mid 1990's. Back then we used JR 2721 servos to activate and they were barely enough. It calls for the 8411 now which work excellent. BV developed this system a long time ago and removed it from the market when the dual rate brake valve came out which was followed by the Smooth Stop.

Is it hydraulic or pneumatic?

Proportional or not?

Pneumatic
Proportional

Obviously a bad assumption on my part. He seemed to be working (or at least flying) with them a lot last year, so I had assumed that he was working with/for them.

Bob

Is it really pneumatic? I'm surprised that you can get enough pressure out of a small cylinder like that to generate a sufficient stopping power with a pneumatic system - given the volume of a typical jet brake system. I would think that you'd need an incompressible fluid to stop a heavy jet with that cylinder...

As of now, it's marketed for the Electra,F86/Fury and the E Bandit.
The heaviest one of the three is the E Bandit @ 19.5lbs as advertised.

I think I still have the cylinder on the plate in a drawer from the original BV set up. You are right though, it WAS barely enough. I also had the Fio brakes, where were hydrolic and I could never get them to work.

I bought the system from BVM in the 90's and never had a servo at that time that was enough power. I recently bought a high power Hitec servo and still barely enough. Mine line length from the cylinder to the brakes was long, approx 40", and I think that is a problem. Just requires too much volume in my installation.

The 8411 drives the cylinder with ease. In fact when I CA'ed the carbon braket to the wooden plate I broke the plate off and then epoxied and screwed it in place.

So far what I have found is to use only BV brake line, the tiny stuff. Make the line run as short as possible. I am installing in an ARF Sabre that is turbine powered and I have the brake valve located just behind the main wheels under the tailpipe.

Very proportional.

Pneumatic only.

It came to life in the early JPX days for the T-33 and F-80. BY the time the original Bandit was out the Dual Rate brake valve was alive.
