I love the BVM pneumatic wheel brakes, but their sooth stop valve is just junk. The one in my Hun worked great for a dozen flights, and then one day at a rally it started loosing air, intermittently, with the predictable runway over shoot and busted nose gear rails.

The E brake looks to be such a simple and elegant solution with no on board tanks and no compressor required..

I might do some testing as I have one of the large cylinders to hand.[/Q

I tried this unit several years ago and wasn't successfull, probably my install. If I used it again I would probably put the brake servo on separate battery.
