Hydraulic trailer surge brakes means no parking brake?

[[email protected]]

Forced to replace my snapped Komet III trailer tongue, the American/
modern answer for surge brakes seems to be hydraulic (versus
mechanical), or maybe electric. But either seems to eliminate the
possibility of parking brakes.

Without parking brakes, I'd have to use chalks. This is certainly
less convenient and I find the parking brake at the tongue to be
useful for hillside manual maneuvering of my trailer...

Any suggestions?

Thanks,

Have you talked to the Komet folks about a replacement tongue
assembly?
Should be no reason why you can't get a replacement that funtions the
same.

Hydraulic parking brakes seem to work fine on aircraft ranging in size
from a PA-28 to an MD-11. I can't see any reason they could not be
used on a trailer.

What are chalks?? Is this another common language thing?

You use them to mark the place where you left your un-braked trailer.

Possibly a spell checker thing, if using the "Dan Quayle Spell
Checker" plug-in.
Chalks are a bit like crayons, but some children don't like the taste
as much.
News of a hydraulic parking brake actuator to add to a hydraulic
surge brake system would be welcome.

That is funny!!!

Since no one else is going to pipe up, the correct spelling is
"chocks".

Thanks. I was about to screech. :)

Since when do you leave hydralic brakes locked on aircraft? Chock
(chalks if you prefer :-)), tie down, unlock brakes. Right?

I know, it's no fun, but... An ANSWER to Eric's question! (and mine,
too)

KSport makes a hand brake for rally cars which is a hydraulic
actuator. It has a lock, so can be used as a parking brake.
Believe it's T 'd into the hydraulic lines between the actuator and
the axle

Ever try moving a trailer around by hand on even a slight slope with
no parking brake? You can't run to the axle to chock the wheels in
time.
Better bring chalk!

What's you point? You don't need to leave them locked on a trailer
either do you?

But yes, I leave my PA28 parked with the brakes on if there are no
chocks or tie downs available.

Dumb old mechanical brakes on a trailer may not suffer the same
problems as hydraulic brakes do. Hydraulic brakes on aircraft can
suffer hydralic pressure leak down while parked, setting brakes when
hot and then not being able to release them etc. Varios POH provide
various different warnings/procedures for parking with hydraulic
brakes. Wether it is a good idea or not almost all trailers at
gliderports I fly out of have the parking brakes left on regardless of
weather the wheels are chocked. I know owners in the UK (ie. lots of
corrosion inducing moisture over winter) who have had problems with
brakes seizing on their trailers so maybe its best we don'g all do
this, but we do. I'm suggesting we all may have more problems with
hydraulic actuated brakes left locked on. I'd hope hydraulic brakes
provide other benefits, including less adjustment being required.

For people who don't think you really need a manual brake on the
trailer I hope their gliders are a lot lighter than mine (most are)
and they never go anywhere with a sloped surface where they need to
manhandle the trailer. Just manually swinging my ASH-26E trailer on
the level looking cul-de-sac I live on is a handful just given the
high camber on the street.
