Youve already sent me your 10 commandments Paul. *But I think I'm
going to go with hydraulic so that I don't have to worry about
maintaining a battery for break away and so anyone can hook up and
pull the trailer.


Sounds like you were about already decided on the hydraulic, anyway.


I'll toss out one factor in favor of electric that nobody has mentioned yet.


If you have electric brakes, and a sway starts to develop, (seems to be a
common theme with glider trailers) or has already gotten well developed and
getting REALLY hairy, a slight tap or easy pressure on the brake controller
will straighten up that trailer RIGHT NOW ! ! ! *It is amazing if you have
never used electric brakes for that purpose.


That reason in itself is the _best_ reason in the world to go with electric.


Shoot, go for two axles, get reduced sway characteristics, and put electric
on one axle and hydraulic on the other.


The argument that the tow vehicle can only be your own does not hold water,
in my opinion. *In most cases the controller will work fine, and in some,
the new vehicle might have to adjust the bias, slightly. *Not a big problem
in most cases. *If you go electric, make sure you use a standard plug, and
have it wired according to standard, also. *Get an electronic controller
that is easily adjustable if you want to tow other people's trailers.


Re-think your decision, I think.

No one even mentioned how hydraulic systems can be a bigger headache
when they start to give problems. Rebuilding master and wheel
cylinders, bleeding, leaks, etc. I've had my share of hydraulic brakes
on trailers. I'll take electric any day just for that reason alone.
Although the instant sway cancelling is another big advantage that
I've used on occasion.

Obviously you all have an opinion about all the stuff that I didnt ask
about


Hi Tony,

Apparently not, I haven't ever seen disk brakes on a trailer so I
can't have much of an opinion on them. My only concern would be that
trailers tend to sit out side a bunch and I wonder if corrosion on the
Disks would be a concern.

yea, one of my local friends had the same concern which prompted me to
put up this post.

You all should be happy that you have me thinking strongly about
electric brakes now.

Good. I think you are headed in the right direction.

You know, if everyone is using one type of system, be it brakes or engines,
or generators, or whatever, there is usually a good reason.

Same holds true with brakes. IMHO, surge brakes are for rental trailers
and such, where some minimal braking is needed and it will work on any
vehicle. It does not need to be precise or adjustable or highly
controllable. Electric brakes are all of that.

As far as the maintaining of the breakaway battery goes, you hook it to the
tow vehicles power and every time you drive it, it charges. Take it inside
for the winter or put a trickle charger on it, check the water twice a year,
and you should have a good battery for several years.

Every controller I have seen has an easily activated manual lever or
button. Have you seen any that do not have that feature?

It doesn't seem to be a problem for airplane disk brakes, or all the
cars that sit outside. Drum brakes can rust, too, in a humid enviornment.

I've seen boat trailers with disk brakes. They probably get a little
wet now and then...

I would suggest looking at option of mechanical drum brakes.
No electric compatibility issues
No bleeding issues.
Cobra builds more trailers than probably anybody in the world for
gliders and they use mechanical. Look up options available from ALKO
out of Indiana.
FWIW

Living and flying in Europe, I have never seen anything else than
mechanical overrun drum brakes. You hook them up and are good to go,
with no compatibility issues whatsoever. And yes, we have montains, too,
and we tend to tug with much smaller cars than our US friends.

Thanks to the mechanical help of a few other club members, the trailer
now has a new hitch and a new Flexride axle with electric brakes.
Next week I'll make a trip to the trailer supply place and get all the
wiring I need to make the brakes work.
