NEED HELP TRAILER BRAKE ISSUES

I tow 34' tt with my 03 diesel ex, I'm having issues with my trailer brakes set the percentage to 65or70% for traveling on the highway but around city driving it is way too much. So I have to turn it almost all the way off before it stops trying to lock the brakes up on the trailer. And sometimes it seems like he high percentage doesn't want to slow the trailer. I took trailer to dealer they said my brakes were too loose so they tightened them didn't help. Is it my controller box that is the problem it seems that even if I barely touch the brake pedal the box goes straight to highest percentage I have it set at is there a particular one that actually only applies the amount of "juice" to the brakes for the amount of pedal I'm applying? Any help will be helpful THANKS!

Nope just the plus/minus button which I believe is the same function.

If you are using an old "timed" controller, the brakes ramp up depending on how long you foot is on the brakes. With the proper equipment, testing a brakes controller takes only minutes and you will immediately know if it a controller issue. With a timed controller, the only thing the controller responds to is time on the brake pedal.

What controller do you have?

Well prob first mistake it's a reliance I was in a pinch my old box went out in the middle of a trip to Florida only place close was walmart so I got one there
And by "ramp up" you mean apply more pressure it seems that this one works backwards of that theory

With a timed controller, which the Reliance is, you set the max output to the brakes and the longer you have your foot on the pedal, the more the controller approaches the maximum setting you have punched in. I do not know if this is your only problem, but the only advantage of a timed controller is cost. A controller with an accelerometer is smoother in every way! My opinion based on my experience.

By the way, the dealer who said your brakes were set too loose was silly. Do not go back there. Did they test the controller output to the brakes in amps?

So if my tt is under warranty and they don't do the job properly what should I do? My tt is a 2010 rockwood signature ultra-lite 8315BSS. Can I take it to another rock wood dealer?

The problem is your trash can. It doesn't have that Reliance unit in it! I wouldn't even consider towing a trailer that size without a high quality proportional (inertial) brake controller. I've owned lots of controllers over the years, and I think the Tekonsha Prodigy P3 is the only one to have (with the exception of the newer integrated units which are pressure driven). It also has an initial boost feature that lets you fine tune the immediate output voltage to the needs of your truck/trailer combination.

I just ordered one of those controllers. From replies in this thread and other research I figured this is a wise choice thanks

Any Rockwood dealer can service your trailer undewr warranty. It used to be anyone who was willing to accept your warranty could work on it, but the dealers have gotten together and locked all independents out of warranty work. Independent technician make up the overwhelming majority of certified technicians in the industry so you are actually more likely to find certified technicians at other than dealerships. Sad, but true!

So I guess I need to find a tech close to me and pay out of pocket to get it right because the guys that looked at mine were very shady. Guess I can google that info
