Dexter had some problems with the 10K axle brakes as well as leaking seals.The 10K brakes on the one i had would self adjust going forward and grab.Some people changed to the 12k axles with a different style backplate brake and a different seal.I know they were sued over the 10k axles.

I've never had a problem as long as they were
adjusted and the magnets were working. Is there
oil in the drums? They also need to be adjusted
pretty tight. I always adjusted them up til I got
just a bit of drag them by the time they were
broke in they were set about right. They should
easily slide the wheels when its empty. You didn't
put them on the wrong side did you? If you
replaced the entire backing plate you can get them
on the wrong side of the trailer, they are right
and left and should say on the outside of the plate.

Yea.Ive had numerous problems with mine. Maybe 3000 miles on trailer and its been repaired 7 times. I think its right now. Hot hubs,leaky wheel seals, dragging/sticking brakes.

I had several customers that had problems with leaking seals. On several I just greased the bearings and eliminated the oil, they never had a problem again. One guy had a 35' Featherlite that he pulls to Arizona a lot and he's still doing that. Says it's never been so reliable.

Is a poor short drawing 11.3 amps or the brakes proper? I've got a
short somewhere in my trailer wiring harness. I've been from one
end to the other twice and fixed a few bad splices but no shorts, its
still not letting my brakes apply correctly. This summer its getting
flipped over to get some rust repairs and hope to find it. I'm
beginning to suspect the breakaway battery wiring.

Check and make sure that you have a good ground, also
what size wire are you using. Ground wire should be
#12 minimum, others should be #14 minimum, brake
wires should be # 12 min. also.

We couldn't get the new 8000 lb. Dexters to work on my son's
trailer either. By luck one day he was checking connections and all
of a sudden all of them came on. When they built the trailer they
had a coupling that was for a tri-axle trailer. They cut the 3rd wire
and didn't seal it good. It was shorting out and not letting the
brakes come on.

You have a wring issue. It is either a bad ground or your not getting the correct voltage at the wheels. You are saying it is drawing 11.3 amps. Where are you checking it??? Also what is the voltage right at the magnet?? That is a better measurement of what is going on. You can have a 11.3 amps at 8 volts and not have much magnet force.

Also what did the back surface of your drums look like??? This is where the magnets run. If that surface is scored they will not work very well. Did you put the spring behind the magnet that pushes in out against the drum??? I forgot on one wheel and the brake would work sometimes and sometimes not. Drove me nuts until I pulled the drum back off.

I have two trailers with Dextra 10K axles. They work good if you keep them maintained. The only issue is the wiring will break inside the insulation from all the bouncing around/wiggling the wires do hanging down to the axle.

Make sure they were installed correctly, and
turning the right direction. They use the proper
direction of rotation to mechanically amplify the
electrical signal.

I replaced all the magnets.. had to try several different types of seals to get ones that workd.. I soldered all wiring at the brakes... get 12.5 volts to each brake,, but they just basically suck.. Almost NO brakes what so ever. The controller will lock up the other trailers but nothing on the 36' gooseneck. Its not a short as each magnet is suppose to draw about 3 amps, so 11.5 amps for 4 brakes is about right. You can push in the clutch, reach down and peg the controller and not feel any significant slowing..

I bought a new single axle with 3500 pound brakes last year and had the same problem. finally called Dexter and they said to adjust them and drive it making a lot of brake applications, they had to run in. They were right, before long they were working properly
