Trailer Brake settings

Before I left the dealer parking lot, I played with brake settings, and a very helpful tech (thank you Billy of Lonestar RV in Houston) helped me out. We started on 12, but that would yank the TV to a stop. I finally left the dealer with my P3 set on 8.2. It "felt" ok. Didn't feel the trailer pulling me, braking from any speed. But, the brakes smelled a little warm on the TT when I got home. The TV has absolutely amazing brakes, so I started backing my P3 down. I walked it all the way down to about 2.2 before I really noticed an increase in braking effort on the TV. Is there and "science" or method to set the gain, other than seat of pants and experience.

I think there are a couple different methods including the "feel's right" method.

If you look in the instructions for your brake controller, I believe you'll find that it will say something along the lines of "pull your trailer up to 20 mph on smooth, flat, dry road and fully apply the manual brakes; increase the gain until the trailer tires lock up, then back the gain off until just under the amount where the brakes lock up."

That being said, I could never get my trailer brakes to lock up, so I do it by feel; I can just barely feel the trailer pulling on the truck when I stop. If I back off .5 on the gain, it feels like the truck is struggling a little to stop the load, if I go .5 higher, the trailer pulls the truck too hard during a stop.

P3 manual says to drive at 20(25?) mph and apply the TT brakes manually to full. If the wheels lock up, back it down. and repeat. You want the most you can get w/o lockup.

Big heavy trailers may not lockup even at 10. OTOH, you may find the max found above is a little too much...backing down a few is ok.

Make sure you test with a loaded for camping trailer.

I do remember reading the 20mph lock up thing, but that seemed kinda ridiculous? Guess it's that or by feel.

As long as the TT isn't locking up, or pulling the TV, is it possible to have the gain too high. Maybe the brake smell was just new pads bedding in?

On the P3, make sure the boost feature is off when you are trying to set the gain. I hardly ever use the boost feature...I may set it to "1" once we are on the open freeway but most of the time it stays off.

+1

The "Boost" feature can be nice sometimes. Also, don't forget to turn it off when you're slow maneuvering. If you forget, it will remind you, but the reminder is rather unpleasant, so it's better if you just turn it off before you have to dig the steering wheel out of your molars.

It just occurred to me, that the gain setting also affects the manual control doesn't it? So I could use the manual lever, without putting my foot on the brake to "feel" how much braking the trailer is actually doing?

That's where I would start. Then when you think you've got it where you like it, try it with the truck brakes and see how it feels.

Great, now I have some direction to set it that doesn't involve brake lock up, sheesh.
