08 ford F250 SD ... New Jayco TT .. Brake Issues

[Jamtorky]

I have a 2008 F250 SD and a new Jayco 30BDHS Jayflight ... I hooked my TT up and followed the Brake set instructions in my Owners manual and here on the site..

I took the brake controller all the way to 10(max) and the wheels did not lock up ... The trailer manual indicated that it will take about 1000 milles or 50 good hard stops to seat the brakes ..

any one have any suggestions???

Oh, boy . . ..

Multiple issues here, and trust me . . . I've been there, done that, and buried the shirt.

Issues - in no specific order:

(1) Make sure the brakes on the trailer are properly adjusted and functioning (just because they're new doesn't mean diddley!!);
(2) Yes, some braking cycles will be required for optimum pad to drum contact - 50 hard stops?? Hmmm??
(3) What controller are you using? Many of the "budget" controllers just don't have the guts to pull down a heavy trailer. I happen to be partial to the Tekonsha Prodigy (although there is a "newer, better" unit out from them). It will haul down my 17K# race car trailer with authority. Which is more than I can say about the previous 2 controllers I had, which both darn near got me killed!!
(4) Very important!! Make sure the wiring to the brakes from the controller is heavy enough (8 gauge is smallisn, IMHO) to handle the current, and that both your hot and ground connections are good.
(5) You may NOT have (or want) enough braking to lock up the wheels at speed on pavement. You should however, be able to manually apply full braking and slide all 4 (6?) wheels on gravel - easily.

Hope this helps!

The brake controller is the intergrated one that comes built into the truck .. not really interested in getting an aftermarket one if I do not have to ... I'll have to check with ford about the wiring for the truck and Jayco for the wiring for the trailer.


I'll have to check the ground and hot wires as well

thanks

Some of the earlier Ford controllers did not allow lockup under a certain speed. I thought they had changed that due to customer complaints.
If your sure your getting power, I'd take it to the dealer for a checkup.

I am not sure about the '08 model but my '06 integrated brake controller interfaces with the anti-lock system. Check your owners manual for the Tow-Command system and see what it says.

I have an `08 and my integrated brake controller locks my trailer brake while at a stand still. This is one of my safety checks before pulling out. After the 5er is hooked up and visual inspection looks good I raise the landing jacks so that they are JUST off the ground. Then I lock the trailer brakes and gently step on the accelerator. This insures the kingpin is locked in the hitch.
