My first Panic Stop

Folks,

I have a question about my Tekonsha P3 brake controller. I thought I had it set up right and haven't really checked it since I set it up. We were heading home up RT 50 from Delaware last night. We were driving at about 55 in heavy traffic. I was leaving a nice distance in front and a van cut in front of me and then hit his brakes. I had to hit my brakes HARD and my anti-locks on my truck kicked in and it felt like the trailer didn't help much at all. When I got into my neighborhood I was going 25mph and did the manual brake engage on the P3 and the trailer tires didn't come close to locking up. I had it set to about 7 but they didn't really grab hard until I had it close to 14.

Is it normal for these settings to require adjustments or did I have it wrong in the first place?

Just looking for opinions as to why the settings may have changed.

Thanks!

Marty

Could be your trailer brakes need to be adjusted.

Looks like you have a fairly new trailer. New brakes take a while to wear in and usually need some adjustment after the first 1000 miles or so. Easy to do if you have a good jack. I would not adjust the controller until you have the brakes adjusted. it is a good idea to check the brake adjustment at the beginning of each season.

PS You did good if you only had one panic stop on Rt50 yesterday.

Wow. I love this forum. I have some DIY skills but I am not automotively inclined.

I will check and adjust the brakes.

brakes

Its always a smart thing to do , leaving lots of space between you and the vehicle in front of you. I would first take it to a licenced garage to have the brakes adjusted, not a TT dealer.... There is a lot to consider when adjusting your brakes on your TT. For example, did you set it up when the TT was empty or loaded, had the TT been sitting for a few weeks etc....
So for sure start by getting the brakes adjusted by a mechanic and go from there for your final adjustment...
Hope this helps you out a little.
P.S. it took me a while to finally set up my P3.

Once your brakes are adjusted, go follow the instructions on setting the P3. I also use the P3, and 7 sounds way low. That's about what I set on gravel roads to keep the trailer from skidding. I set at 10-11 while on good, dry pavement.

There are too many idiots out there, I would also suggest getting a dash cam. If they had cut you off shorter, you may not have been able to avoid a crash. My daughter is a truck driver and suggested that I get one. She said they never drive without it.

x2 x3 x4 Never liked that road ever since a car from PA decided to pass and almost hit us head on, at dusk.

I own 3 trailers with electric brakes all three require different settings on the brake controller.

Some brake controllers have a leveling sensor which adjust the braking for the grade. Could this have been your issue? Less braking going up hill and more braking going down.
