2012 Ram 2500/ProPride Brake Issues

Just returned from a three week 3K mile trip and I experienced a problem with the ProPride hitch. On three different events when I had to hit the brakes quickly, not a panic stop mind you, just quick application of the brakes, the yoke slipped on the ProPride forcing the trailer over to one side causing the steering wheel to feel a pull. One each event I stopped at the next opportunity and readjusted the yoke.

I suspect the problem is with the trailer brake application and possibly the operator in the Ram. It has four different basic setting, with ten different adjustment steps. The basic settings are "Heavy Electric", where I originally had it set, "light electric", "heavy electric over hydraulic", and "light electric over hydraulic". Originally I was using HE 10 when the problem happened. The brakes felt good, but there did seem to be a slight delay between the truck and trailer brake application.

I have now tried all four of the basic settings, and have decided that HOE (Heavy Over Electric) works better and seems to have less delay, but the yoke on the ProPride has slipped yet again. I have actually tightened it so tight that I have gaulded one of the "U" bolts and will need to replace it.

Anyone have this same experience, and/or have a solution/suggestion?

We have a Ram 1500 with factory brake controller, FC 25, and ProPride. I usually set the brake controller each day when starting out so it feels right, not paying much attention to the setting but I believe it is much lower than 10. I use the HE setting. Never any problems with it but have only a few thousand miles with the ProPride.

I've only had one emergency braking and all went well, no movement of the hitch mounting, although there as some pulsating in that event that I attributed to the anti-skid brakes of the truck. Everything stayed in line, one deer ran by the front of the rig and the other behind.

Steve, it sounds you're on the right track questioning the delay of the trailer brakes after the truck brakes, perhaps getting the "Hensley bump" and pushing the hitch head to the side? Could the trailer brakes be worn or out of adjustment, or could one side be grabbing before the other? Sean at ProPride may well have the best answer.

Doug,

The trailer brakes feel fine, are the newer self adjusting variety, and even seem too strong at times...sort of grabby if set too high. Definitely get the "bump" when this happens, and then afterward the steering wheel is pulling to which ever side the thing slipped to, and I can see in the mirrors the trailer is off to one side or the other.

I just talked to Sean and he is sending me new "U" bolts to replace the bad one, but I have reservations if the new bolts will effect this issue.

I really don't want to get into changing the brake controller to a different model. I never had this problem with the same hitch and same trailer when I was towing with the '08 GMC 2500.

It seems the Hensley bump is always associated with delayed or not enough braking at the trailer, as I recall reading. A 10 setting of your controller is high, isn't it? Could there be a corroded or poor electrical connection between the pickup and trailer brakes, causing a voltage drop and therefore weak application? Can you lock up the trailer brakes with it, as a check?

Have you talked to the Propride people? What did they say about it?
Whose brake controller is it? Have you talked to them?

The trailer brakes are working fine, as good as they every have as far as strength is concerned. When I have it set on 10 on EOH, it is way too much braking.

I have talked to Sean and he is sending me new "U" bolts and hardware, and he seems to think that will take care of it, but I am skeptical. Sean did tell me I could put an additional bolt in the slot on each side to help reduce the chance of the part sliding, which tells my skeptical side that this problem has come up before.

The brake controller is Dodge, built into the truck, and my personal experience with talking to a dealer about such an issue is like talking to the wind. Actually, not as good, as the wind won't give you a stupid look and insinuate that you did something wrong.

Is it possible that the trailer brakes are "turned off" so quickly that the stored energy pushes the trailer forward a few inches? Similar to someone running across in front of you when walking briskly, your feet stop, but the upper torso wants to continue forward.

My TV is a 2012 Dodge 2500 Cummins with automatic and I use 5.5 to 6.0 on the Dodge control head pulling the 25FB Int'l with GVW of 7,300 pounds. If you have not tried this, you might get on an empty straight road in a rural area and try a lower number on the brake controller and work upwards and see what happens.

I worried about stripping the U-bolts and started out with them way too lightly torqued when I first installed the hitch. It took me 3 trips, with the U-bolts torqued a bit tighter each time, to get the yoke where it would not slip when backing into a campsite. In each case, the yoke was OK when I arrived at the campground, but slipped when backing.

I have to back rather tightly into my storage building and I have learned to expect the "bang" when starting back. The yoke now stays put, though.

ProPride should specify a torque on the U-bolts so that we know where to start.

It is my belief the brakes are not coming on fast enough, like there is a delay between the truck and the trailer brakes. This only happens when I have to stop quickly like when some (expletive deleted) cuts in front of me in traffic and hits the brakes to stop at a light. I feel it, and hear a "bang", and then feel it in the steering, and see the trailer tracking to one side, or the other after.

John, I remember there is a spec, and is in the instructions, but I don't remember the exact number. I do remember thinking that it wasn't too much, so shouldn't be such a big deal.

I never had this problem with the GMC, my previous tow vehicle, so I believe it is caused by the brake operator.

Have you asked a Dodge dealership to check that your truck has the latest programing which might also impact the brake controller operation?

I have called the service rep at the dealer to try and start getting information about the brake controller. I got his voice mail. Left a message for him to call me back. I'm waiting....

The EOH brakes do have a delay in application..it is a common complaint. There is no pressurized fluid reservoir like autos have. When the actuator gets the electrical command, the pump must turn on and build pressure....thus the delay. I was able to reduce the delay by bleeding the brakes thoroughly....a challenge as the inboard caliper half has no bleeder. I had to loosen the brake line to bleed the inboard ones.

Clean electrical connections, as noted above, are essential.

Rich,

Please understand that I DO NOT have hydraulic brakes on my trailer. It just seems that the EOH brake setting on my '12 RAM 2500 has less delay in the controller than the electronic brake setting.
