Ventus 2cx brake

Hi Pilots,

I have a V2cxT that has the standard S-H disc brake that no longer
works very well. *I have been through the obvious fixes; pads, new
fluid, bleed, etc. and haven't been able to bring it back up to
original performance which was adequate but not stellar.

I know a number of pilots have complained about this world-wide and S-
H has issued a voluntary TN. *The fix is to basically throw the old
stuff away and replace everything including wheel and tire with the
French-made Beringer system. *Beringer makes performance brake systems
for motorcycles, aircraft, etc. *It is not cheap and probably not an
easy install.

Does any one have first hand knowledge about this fix? *How easy is it
to install and what are the performance gains? *I hate to lay out the
cash without an understanding of how much of an improvement I will
see.

Let me know, thanks.

I believe I have seen a spoiler actuated brake system on a Nimbus 3,
maybe SH could provide the parts to convert yours. You can get some
real muscle into the system when the wheel brake is actuated by the
spoiler handle.

Is there an operational reason for putting the brake on the stick
instead of the spoiler? As opposed to, say, cost reasons?

I've always preferred the wheel brake on the spoiler handle, even though
it sometimes confused people when they saw the spoilers open as the
towplane began to take up slack.

I have had gliders that did it both ways, and it seems to me that it is
easier to modulate the brake in small amounts with your hand than with
your entire arm. But that could just be me.

I notice that the new 304S still has the bicycle brake lever, but has
moved it to the spoiler handle. It would seem that there are advantages
to getting it off the stick, including the possibility of having the
lever directly act on the hydraulic cylinder. I wonder if the 304S does
it that way, or still uses a bicycle cable going to the cylinder.

Perhaps it's the glider. I found both my ASW 20 C and my ASH 26 E very
easy to modulate. The wheel brake takes more force than holding full
spoiler at landing or takeoff speed, so it's easy to know when I am
applying it. It's easier for me to modulate the total braking effort
with one arm (brake on spoilers), instead left arm (spoilers) and right
hand (wheel brake).

Possibly. If it is necessary to move flaps to a negative setting
right after touchdown, that means releasing the spoiler handle in
order to move the flap handle. If the brake is on the spoiler handle,
that also means that the wheel brake must be released. If the brake
handle is on the stick, the wheel brake can be held on with the
bicycle brake grip while the flap handle is moved.

I favor both as with the Duo Discus or heel brake as with the LS-3.

I use the wheel brake stick grip by shifting my grip such that
rearward force on the brake handle also pulls the stick back to help
prevent a nose over and keep maximum down force on the tailwheel to
prevent a ground loop. My left hand is then free to shift the flaps
to max negative and return to the air brake.

Several reasons:

(1) No spoilers (like the HP-18 or my whale mentioned above)
(2) Some people hate messing with spoilers to prevent rope
overrun at hookup, because of operational considerations
or because...
(3) Many gliders pull down flaps with spoiler activation, so
if you pull spoilers back to use brakes now you need to
push flaps back up (take-off and landing)

I think that's why many gliders have both...
Why it never works ? A long rant plus discussion above...

Hope that helps,
See ya, Dave "YO electric"

Which gliders add flaps when spoilers are activated?

IIRC, LS, DG, Lange...

Ventus A/B and many Glasflügel ships.
