Trailer making my SUV lock up.

I have a Jeep Cherokee SUV with towing package, and am pulling a Coleman travel trailer. I have a weight distribution bar.
It has electric brakes.

Without the trailer attached, I can go any speed I like.
Today, with the trailer attached, when I get up to about 50 MPH +, my SUV back brakes start locking up and smoking.

Things to know. I towed the vehicle with no problems for two summers, and earlier this summer with no problems..
I recently redid my back brakes on the suv, and have not towed the trailer until today.
I also added a sway bar to the trailer hitch between the last time I pulled the trailer, and this time.
When the brakes lock up, I think the ABS on the SUV is activating as well.

I would appreciate any opinions on this issue. I intend to travel across 3 states next week, and obviously cannot do so with this issue.

I searched these forums and the web about 3 hours before I posted this.
Thanks in advance.

  • Tell us more about your Jeep Cherokee? XJ (84-01) or a KL (14-present). My guesses, it is an older Jeep, since you replaced the rear brakes. I am going to guess you are using the brakes harder, and the calipers are sticking. Just a guess I pulled out of my head.
  • I agree, very strange behavior. I'm going to subscribe, as I'm very interested in any ideas.
  • Wow, I've never heard of that and I have been here a long time. Do keep us posted as to the cause and I trust someone here can help you.
