Cool Trailer brakes won't lock.

Greetings All, and Happy New Year.
We picked up our new 5th wheel last summer, just as we were heading out on vacation.
I have not been able to get the trailer brakes to lock-up.
The trailer brakes do work, and will slow both vehicles, but they will not lock.
We have had several different trailers over the years, and on each of them the brakes would lock. It was the point of lock-up that we used to set the controller gain.
Has anyone experienced a similar situation.
Your comments and suggestions are appreciated.

I had a similar situation with mine about 5,000 miles from new. I adjusted the brakes and although they did improve, they didn't perform as well as new. I took it back to the dealer who found that the grease seals had failed and grease was in the brake drums on 3 of the wheels.
I would suggest getting your brakes adjusted. If that doesn't work it's time for a complete brake inspection.

Thanks for the reply Racedrvr. The brakes have been adjusted with no inprovement. Will check the grease seals as you suggest.
Thanks again.

How old is the trailer? The electro magnets that actuate the brakes lose power over time and might need to be replaced.

If new another suggestion is that they were installed improperly and need to be redone. I have seen the wrong brake shoes put in Semi trailers before so this might be the issue. Part numbers can be confused.

Interesting... I've only owned two TT and either would completely lock up the electric breaks (dry surfaces) even with the controller all the way up. These TT's and FW's are loaded down to 80-90% of their GVWR. They are not empty utility trailers bouncing around and locking up a tire at each stop light.

I'm no expert that's for sure, but I don't think my F-450 coach would lock up either (ABS disabled) nor would I expect it to loaded up to its max GVWR (14,500lbs).

What do you do when the road surfaces change on you while traveling? Are you constantly adjusting the gain with one hand while driving? I must of been doing something wrong back in the day as I adjusted the controller once per trailer, remembered the number, and left it alone for years at a time.

Why do you want them to lock up ???? I do not want mine to lock up ! Just want them to stop the trailer...... 10 -14000 plus lbs of trailer is alot of weight to have the tires lock up. I locked the brakes on an empty cargo trailer.....flat spotted the tires & had to replace them.....

WE had the same issue with our Sabre. Dealer inspected and found as Racedrvr stated, found grease in the brakes, inside grease seal was bad. I use the locked up brakes to make the 5th wheel slide in the truck. Short bed truck, have sliding 5th wheel for manuvering the 5er.

When my 5th wheel was delivered, the brakes hardly worked at all. The dealer checked out my drums and brakes and found them properly adjusted and without any foreign oil, etc., causing problems. Then they took the trailer out on the road and applied the trailer brakes moderately a few times, following a specific procedure they received from the axel manufacturer, so as to not over heat the drums. This procedure set the brake shoes to the drums. Again, this wasn't just randomly done, they used a procedure they received from the axel manufacturer. This fixed my brake problem. You can find bed-in procedures on the Internet but be aware that different applications require different procedures.


It is not uncommon for it to take 300-400 miles of moderate brake usage to set the shoes to the drums. Also, it isn't uncommon for early hard use or constant rubbing of the brake shoes on the drums to glaze the brakes, which causes them to stop working properly. Rather than just going out and trying to set the breaks, ask you dealer or a brake shop to check them out or get the procedure from them and do it yourself.

If you have an integrated brake controller in your tow vehicle, you won't be able to lock up the trailer brakes since, among other things, it's designed to prevent that.

ABS prevents the brakes from 'locking up', once the tires lose adhesion all of the stopping power is out the window. Out of control.
