I still vote for surge but electric have moved up in my opinion from
years ago.

Dan, FYI, I had a travel trailer with electric brakes, and the type of
switch that attaches to the brake pedal of the truck. I had a VERY
hard time adjusting that the way that I wanted, so I bought a
controller that uses a dampened pendulum. After a few minor
adjustments, that thing works VERY nice. I've got it adjusted so that
it doesn't skid the trailer, but works so well, it stops almost like
I'm not pulling anything.

So I'm back to this question again. I thought we had it settled when we
were
going to
have someone else build us a trailer, but now that we're going to build it
ourselves,
all options are open again.

I looked back at the answers from the April 10, 2003 thread "Trailer Brake
Questions" and at
other sources on the web. Any other information or comment would be
welcome and appreciated.


ELECTRIC BRAKES
+ More control over the braking
+ The brakes work in reverse, which might help at the ramp
- Might cost more ?
- Can't use in (salt) water
(Some people said they use in water without problem. Maybe
special/newer
models)
- Any tow vehicle has to be wired for it.
- Have to have & maintain a backup battery on the trailer to activate the
brakes in an emergency separation.

ELECTRIC over HYDRAULIC:
This is where the controller is electric but that controlls a hydraulic
master cylinder.
+ Still have the finer control of electiric.
+ The brakes work in reverse
+ No problem in water as the electric is no in the water.
- Higher cost?
- Tow vehicle has to be wired for it.
- Have to have & maintain a backup battery on the trailer to activate the
brakes in an emergency separation.

HYDRAULIC-SURGE:
+ Self contained on the trailer, no special wiring on vehicle
+ Works fine, possibly lower cost.
+ Can have free-backing brakes or reverse-lockout-solenoid so brakes are
not
active when backing.
- Breaks do not work in reverse...which you might want on a steep/slippery
ramp.
- May be illegal in some states ??


QUESTION:
On a hydraulic system, if there was any problem with one fitting or line
would that
mean the breaks on all four wheels (dual-axel trailer) would stop working?

Hi Gary,

I just returned yesterday from a 10 hour ride from far Upstate NY to
Northeastern NJ to pick up a CHERRY of a trailer. It is hydraulic,
with stainless steel disks on one axle, (twin axle trailer).

We had a panic stop situation in heavy rain, unloaded trailer. The tow
vehicle, (Chevy Astro van), has antilock brakes. We stopped short and
straight, leaving me no doubt about how well the trailer brakes work,
even without a boat.

The seller advised letting air out of the tires for a better ride, but
it seemed to, "hop", all the way home, seeming to develop a
vibration/occilation of sorts that would start when we hit a small
bump, and continue for a second or two. It wasn't the brakes locking
up in any way. Anybody know what would cause this? Is it just a
product of the empty, flexible trailer? (FWIW, I'm a professional
driver, so the trailer was thoroughly pretripped, and everything was
tight).

Also, the hitch receiver, and the corresponding hitch bar that has the
ball attached, RATTLED all the way home, driving us crazy. I know it
won't do this with the boat on, but is there a way to stop this? We
tried a bungee cord around the bottom of the hitch bar, tying it up
above to the bumper, but that didn't do it. If i had a couple small
nails, I would have driven them into the gap as a quick fix. Any ideas
how to stop this next time?

My 2¢
My vote's for standard hydraulic as well.

Reason: KISS

Hope I helped.

The springs are set for the max weight of the loaded trailer and there are NO
SHOCKS on a trailer. If it is empty the springs will not compress much (when
loaded the friction between the leaves provides a little damping) and the bumps
in the road cause an empty trailer to bounce on its tires like a basketball.
Reducing tire pressure somewhat when empty would help, but then you would have
to pump them up again before loading.

Hi JJ,

It's a torsion bar suspension, not leaves, but that probably doesn't
matter. Spring is a spring, right.

This wasn't so much bouncing as it was a sort of vibration. When I
looked in the mirror, you could see the frame doing a very slight but
quick, wave like action, almost like a guitar string, for lack of a
better analogy.

I bet it has something to do with the overall harmonics of the trailer
frame, I just wonder if there was a way to stop it.

And how about the VERY slight play between the square hitch tube and
the hitch bar with the ball on it. How do I take up that slack without
welding it? It's such a tight space.

Thanks.

There is a rubber snubber that goes on the tube. maybe Bass Pro shops or
Cabelas carries them. OR try Champion trailers.

Donny,

Glad to hear of your good trailer experience.

I have just one comment: Keep the tire pressure up to maximum rated psi
and let the springs or torsion bars do their job to smooth out the ride.
Emergency handling and reduced tendency to fishtail will fare better with
higher pressure.=20

On my own trailer with 2700lb load, I was told by the trailer =
manufacturer
who in turn got it from the tire manufacturer that if I reduced pressure
from 50PSI to 35PSI the load rating for each tire would reduce from 1750
lbs to 1100 lbs.

I'd rather have the extra capacity and stability so I keep the tires at
60PSI. The boat is riding easier with tandem axles and equalizers =
anyway.

I like the hydraulic disc surge brakes too.

Hi Lorendi,

This was towing an unloaded boat trailer home from a dealer, no boat.
I'm pretty sure it has something to do with the flexibility of the
aluminum frame. I was just looking for ways to offer up an answer for
the next newbie who has to tow an empty trailer a few hours, because I
really don't see us ever towing it unloaded any farther than from the
ramp to the parking lot.

Thanks!
