Where did you get this? I have heard of loosening the friction sway bars in the rain, but NEVER to de-activate the trailer brakes. IMO ,that is pure insanity.

The gain on the controller should be adjusted so that max output is just short of locking up the trailer. Obviously, that will differ depending on road, weather, and loading conditions and should be readjusted any time one of these changes.

Did you mount you break controller level as described in the installation manual?

I get the same 'thump' when letting off my brakes from time to time, and it's always on level ground, and usually at slower speeds.
I've found (and I'm guessing you did too based on your comment about adjusting your trailer brake level) that it's a slight delay in the trailer brakes releasing. In other words you apply them to slow down and/or stop, and once you have let off your TV brake, you feel the thump of the trailer brakes also releasing.
It's normal, and based on the comments of others I would agree that knowing things are working back there is comforting.

I also use the Equal-I-Zer and I wouldn't expect that to be your issue. Popping (sometimes loudly) when turning is a characteristic of that hitch, but a pushing thump as you described...not your hitch as long as it's hooked up correctly.

Had a buddy use a 2inch ball for more than a year before I saw it and questioned the size, should be 2 5/16 inches.
I had a brand new boat that had a light tongue weight and would clunk but not just on braking, it was trying to come off the ball. Readjusted the boat on the trailer and all has been good.
I had a ball come loose once, found it loose at a gas stop, scared the heckter out of me(just had a chill thinking about it). At every gas stop I walk my camper and truck thumping tires, feeling hubs just doing a good visual on everything.
I am actually proud to have towed so much that I have changed out two hitch pins from wear grooves.
And yes, I am a brake-controller-adjuster guy. As the road conditions change I adjust; I like to use heavy-ish camper brakes and save my truck’s brakes but in stop and go traffic, rain, sleet or gravel roads I adjust them down a bit. I will also manually use the controller to save TV brakes.
Good luck, strange clucks and noises can drive you crazy.
Thanks for being responsible enough to care.

Sounds like you may have the brakes set too light and are doing the majority of the braking with the tow vehicle.

When the tow vehicle is slowing the trailer down more so the ball inside the coupler goes toward the rear. When you let off the brakes the tow vehicle surges ahead and the ball would then clunk forward in the coupler. This is going to be magnified if there is any slop in the receiver of the tow vehicle.

Wow a lot of responses. Thanks to all.

I installed and adjusted the brake controller per the instructions. Set to lock up TT wheels then back off until they no longer lock up. My coupler takes a 2" ball. I also looked and has no means of adjustment that I can see. It is still wet outside so will look a little harder once it dries up.

I contacted Cequent Performance Products to get some information on a different product of theirs. The rep I talked to is their Tekonsha tech support guy. His opinion was similar to a some others here that the most likely cause was when the brake was released the bump/thump was the trailer catching up the TV. It is the the result of a little bit of slop in the ball/coupler and hitch assemblies and the brakes releasing at slightly different times. He considered it normal for being on a hill as long as the controller was adjusted per instructions. So I guess it is just another thing to get accustom to when towing a trailer. Thanks again.

You are fine. Set it up like you did before (per Tekonsha instructions) and go.
