Glad you identified it Tim. Something had to be worn out.. Im glad it was the pad and not the caliper.

I am glad you have gotten it figured out.it was nice getting to talk with you at the Rally!

Thanks! It was good talking to you as well. With this experience, I am thinking about some modifications to my brake system to keep those pads from chattering do much and mushrooming that metal backing plate. Brake grease alone is obviously not enough.

One big lesson for me is not over tightening your wheel lugs! It appears I did that without evening knowing it when I snapped that one off. Not going to carry a torque wrench with me on the road but it would be a good idea to at least know what an appropriate amount of torque is appropriate and what is too much.

Just an update. We are making our way back home and discovered that we lost another pad. We also have one that looks like it is ready to drop.
My brother looked at it and discovered that the clevis pins holding the pads in place are worn and loose, compounding the problem. So, we are once again driving without trailer brakes.

Just as I suspected. We stopped because we heard a strange sound. I replaced the missing pad and the one about to go. As you can see, the tab is bent. It almost seems like the pads cannot handle the strain....
I got these from Inland RV. I was told they are custom made for Andy. If you are out there Andy, maybe you can tell me more about these pads.

Buttercup, there is something dragging somewhere. Loose pins would not cause that kind of distortion to the pad clasp in my opinion. The pads sit loose on the pins and rattle and chatter around until the brakes are applied and the piston pushes the pads against the rotor. An extreme force is bending the clasp. Normal braking would not do that. Are your calipers and spacer bars properly installed?

Well, I believe they are properly installed and assembled. There is not much to them. But they rattle and chatter a lot! They always have. Every bump no matter how small makes them resound loudly. My brother believes that it is the momentum of them slamming into the upper Clevis pin that is making only the outside pads break. Those pads were not lubricated prior to this trip but they are now and with enough inertia maybe they could slam enough to bend during braking. Honestly, I am tempted to weld some extra metal on to them to give them some meat at that area.

Buttercup, here are a couple pictures of my brakes. Maybe there is something different in your installation? Are you still running the original rims that came with the trailer? A large number of balancing weights could theoretically make contact with the pad taband bend it outward?

They do rattle even on the slightest bump in the road. Mine have a small amount of play in them. In fact the whole brake assemble has a very small amount of play as it sits on a couple of posts it looks like. I've never put any lubrication on mine. I agree they assemble pretty easily. Is this happening on all 4 wheels or just a couple of them? I'd be interested to hear what Andy's thoughts are.

Looks like exactly what I have, but yours looks like the play is less than mine. I can see a gap between my clavis pin and the caliper. And the pads themselves slop back and forth easily.
I could create a backing interface to mitigate that. But I just can't believe that a good slam could bend that metal.

I agree the metal should not bend from braking. I know your controller is not set too hard because if it were your trailer would be laying down rubber. Any chance the brake pad is dragging on the rotor excessively causing heat and premature wear? I would think that if the force of braking is bending the metal, it would do so on both ends and not just one. What brand of actuator do you have? Could it be applying too much pressure? I'm grasping for anything now...

Hi, no matter how much pressure is on the brakes, the pads should never come out. On cars and trucks with a different mounting for the pads, the only time that I have seen pads chucked is when the lining has either broken off or has worn down to the metal backing plates. In your case, I would say that the metal backing plates are too weak, possibly made in China. [junk] I would bring a sample to a major brake supplier, to match up the size and shape, and buy some good ones. These are probably something that was adapted from Ford or GM. I definately would not buy anymore pads from who you got these from.

Images: Chevrolet brake pads.

Hi, I just did a quick search and found this image twice. One said 2005 Chevy Tahoe, and the other one said 2003 Chevy Avalanche. I'm not saying that these will work, but it leads me to think that those are GM brakes on your trailer.

I got the pads from Inland RV and they were not cheap. I was told that they are custom made. I have had this set in there for about 6 years and previously lost a pad when I forgot to put the retaining clip on the clevis pin on the rear street side wheel. That spit out the inside pad.

I am using a dexter actuator that I have also had for 6 years and I am using a new Tekonsha 3 axis solid state controller that I just love because I can set the max output to the actuator, thereby ensuring that the tires don't lock up too easily. That is my system.

I'll take my one remaining good pad to the auto parts store and see if they can match it. One thing I can say is that I do not believe the brakes should rattle as they do. The ones on my car don't, so why is my trailer doing it. I do suspect this has something to do with it.
