Help trailer brakes hardly working

I NEED ADVICE/HELP. (We have a prime time lacrosse 38res towed with a ford excursion.) First of all we made it to our second destination, Kamp Klamath, which is on the Klamath river less than a mile from its mouth on the Pacific. Yay.

But we made it here with barely any trailer brakes. Here is where I need HELP. The brakes are adjusted properly per Les Schwab (who adjusted them). When I apply the brakes manually with my Prodigy controller I do get some braking, but not much. So my truck is essentially doing all the braking and a couple of times I could tell the trailer pushed the truck. Does anybody have any thoughts, advice, words of wisdom for next steps?

We don't have great cell or wifi reception right now, otherwise, I would search the forums for advice.

Thanks in advance for any tips or ideas.

Can you turn up the gain on the controller?


I'm a little too truthful, I guess.

You may have a poor electrical connection that is not allowing full voltage to the brakes. Try spraying WD-40 into the connector and then connect and disconnect about a dozen times to clean the contacts.

When a trailer is not used for awhile, the brake drums rust and reduce braking effect. This is worse in humid climates. If you have not traveled much recently, go out for a run and apply full manual braking at the controller for about 10 seconds out of every 2 minutes while driving about 30 MPH. Do this 5 or 6 times and see if the braking improves.

Yes, clean the 7-way connectors for both Excursion & TT.
See if someone at CG has 7-way connector tester & cleaning brushes-we keep one in our TV...
If not, you may be able to find one at an auto parts store.

Do you have the grease fitting for the bearings and if you do did you grease the bearings before leaving?

I had the same problem last summer. Adjusting the brakes made no difference. Turned out I had a broken wire to the brakes and two wheels had no brakes. That was not fun.

To test, I went about 5 mph on a gravel parking lot and hit the brake controller to lock trailer wheels. The gravel showed me which wheels were not locking. Good luck.

These are all great ideas, thanks! Less Schwab did find a broken wire when they adjusted the brakes. Cleaning the connectors and testing seems the next logical step.

If les schwab adjuated them like they would a car, then your brakes are NOT adjusted correctly. For any trailer with drum brakes you need to follow this procedure.
Jack one wheel at a time. Bensure to place the jack under the spring hanger. Using a brake spoon adjust the star wheel until you can no longer turn the tire by hand. Back off three to four clicks only. You should hear some brake drag.
My guess schwab backed the brakes off the normal 10 to 12 clicks.

Once the tt and tv connectors are cleaned you may want to apply some Dielectric grease. Later RJD

Be sure the battery connections on the trailer are clean (sandpapered) and tight. This made a big difference on my Rockwood.
