Skittish Brakes

Our brakes are nuts!!!!!
Since day one, our Jay Feather 22FQSW has had very quickly reacting brakes. This has happened in spite of any setting in our brake controller. They lock-up at the slightest touch of the pedal, and this results in a jerky, annoying ride. Has anyone encountered this issue? Any suggestions? Thanks!

Could be a bad controller.

Grumpy, thank you for your suggestion. The problem could be the controller, but it worked perfectly with our previous TT, though it was a smaller one. If I cannot find any other brake issue, I may have to replace it.....

Need more info. What controller? Did you take the gain setting to zero and work up? Maybe the smaller trailer brakes never worked very good?

If the brakes are way out of adjustment it could cause them to lock prematurely.

Another thing, the controller could have a setting for small trailers and another for larger ones.

SouthCo, the controller is a Draw Tite Activator II, which is a time system. It worked very well with the previous trailer. I have now adjusted the output (braking power) to level 3, so the trailer brakes can slow the tow and trailer assembly. I have adjusted the sync control (reaction time) to the lowest level, to soften the way the brakes reach full output and avoid a too fast braking action. It seems to work at the start of a trip and moving at slow sped, but after half an hour on the road, when we slow down and stop at a traffic light, we are in circus mode. brakes lock un-evenly, and we have noisy, jerky stops. How can I determine if it is an electric brake mis-adjustment, or if it is time to get another controller?

Jhowemka, you could be correct. How can I check brake adjustment? Can it be done on the road? Thanks!

I have the same problem. I have a Tekonsha P3 controller. Sometimes brakes work fine, other times they slam on, jerking us to a stop.

You can mechanically adjust the brakes just like on your truck using the brake tool inserted into the slot on the brake drum. Rotate the tire and adjust until they just start to grab then back off a notch.

My electric brakes also jerk some when I first start out with them, I suspect it is moisture... I always stop my trailer at the first stop I come to when starting out just using the manual slide lever. I think this heats up the brakes pretty good. After that they work just fine...

Like RoyBraddy said to adjust the brakes...

I thought of another thing that could affect braking. The wheel bearings could be out of adjustment causing them to grab erratically.
Kinda a far shot but if you're having the breaks adjusted by a shop its not much more work to adjust the bearings at the same time.

I use a techonsha P3 controller. It's regarded as one of the better controllers.
But it does get very jerky at slower speeds if I don't adjust it down. So I'll set it for highway travel then when I get off the highway I'll have to adjust it to a lower setting. I don't think it should be this way but but for now that's how is is.

Good luck!
