Update: Good decision to take it to a mechanic!

Well, we gave up trying to do the brakes install ourselve and brought it to a shop that works on trucks, trailers, and such. They did the work on the Scamp in one day, and added a gizmo that will turn on the brakes if the camper becomes disconnected from the vehicle by accident, and also noticed that my tires had dry rot down the middle, so I got new tires too. The brake controller fits into a nice little spot in my dash that looks made for it, and I drove home without having to do anything different. i took it down a steep hill and watched the numbers go up on the brake controller. it did feel easier to slow down. You can hear the brakes engage when you stand by the camper as I'm backing into my parking spot according to hubby. So all in all, a pretty good experience so far despite the rough start. Looking forward to taking my next trip, which is partly on busy highways around the outskirts of Boston, and having BRAKES. Thanks everyone for all of the information, encouragement, and cautionary tales.

Congrats on the brakes, and new tires. Life is too short, and trailer tires too cheap to mess with maypops. This stuff is supposed to be fun, not an exercise in roadside repairs.

Angry The saga continues

Well I THOUGHT I was all set, but no. Headed out on my first Scamping trip with my professionally installed brakes, all was going well, liked how well I could slow down and stop with them. Then I stopped to check things about 40 min. into the trip and found the hubs were really hot! The left one too hot to touch, the right one I could touch it for about 5 seconds. Waited an hour and a half for them to cool off, disconnected brake controller, and drove home. They were hot again when I got home. There is a loud squeak now too. I am soooooooo discouraged.....

My first thought is wheel bearings set too tight.
Second thought is brakes abjusted too tight.
Bad way to start a Scamping trip

Something is too tight. I spent a lot of my early adulthood tightening stuff too tight. I ruined a lot of brakes, drums, hubs, alternators, water pumps, etc. and wrung off numerous bolts in the process of gaining wisdom. IMHO the trailer brakes are not supposed to stop the TV, they are there to keep the trailer from passing you when you stop. But then I do NOT belong to the let-me-see-how-small-a-TV-I-can-possibly-tow-with crowd either.

I am wondering how much disassembling and checking for damage I should make sure the mechanic does? This is a really good shop by reputation, it's a truck shop and the mechanic I dealt with was very familiar with electric brakes. I have to think that they will sincerely want to fix it right.

If that's the case, take 'me back, see what the dude does (NOT says). Sounds to me like somebody tightened the axle nuts too tight., but hard to say without looking.

Best of luck to ya.

update: the mechanic started looking at it late this afternoon, with one wheel and hub disassembled they said the brake lining looks fine, the bearings look fine, they took pictures which they will email to me, and they think the brake was adjusted up too much. they will finish up tomorrow with the other side, which was the one that was squeaking and screaming as I drove it. I wonder if they will find something different there. After they fix it he wants me (and I want me) to take it for a test drive to see if the wheels heat up again. My question is, how much heating up is normal on a Scamp 13' with the 7.5" brakes?
Without brakes my hubs were always cool.
Thank you very much for all the help with this.

Tell ya what, yer hubs should not get over like 120F even on a hot day. I carry one of those cheap little laser pointed remote temp sensors (like 15 or 20 bucks from Amazon) and check mine continually. Last trip, real hot weather, I was getting 115 at the hubs. Not the hub cap, the hubs.

I don't know what yer guys are using for grease, but I swear by Lucas Red & Tacky.

Best of luck to ya!

Your 115 was more like 100. Those cheap and even many expensive IR thermometers are NOT made to work in air temperatures much above or below 72F (room temperature). They're kind of like your auto air temp gauge that warns of ice when the air temperature gets to 35. It's too late in many cases, freezing road surfaces can occur at much higher air temperatures. The biggest difference I've see is the road temperature 25 and air 50F.

Just be aware of measuring instrument's limitations. One of the biggest problems in many cases is not knowing or understanding the limitations of instrument being used.

went to pick it up and took it for a test drive. Drove about 25 miles, hubs only heated up a little, but I had very little braking assistance from the brakes. Like, next to none. So went back, they tightened them a little, another test drive, and they were hot again.
Left it there, they are loosening things up, I suggested maybe it was the hubs that were too tight...described the instructions saying to tighten to 40 lbs. and then back off 1/4 turn.
They are going to take it for a test run this time, hopefully it will be all set tomorrow.
Why oh why did I think we couldn't do this by ourselves???

I seem to remember you did try to do the brake pads yourselves. . Hopfeully it will all work out for not too much money and you can get back on the road with it.

remember, you can adjust the brake controller for more power, rather than running the brakes too tight and damaging them

It would be comical, if I wasn't close to tears

So the mechanics tried adjusting the brakes several times over three days, each time with me taking it for a test drive. We could not get the brakes to work without heating up, one side more than the other. Super frustrated, I brought the poor little Scamp home for the weekend, and Hubby took another crack at it. He found that a) the castle nut was tight on that one problem side, but loosening it caused too much play in the wheel for his liking. He found a compromise spot that allowed the wheel to spin freely with no play, but isn't terribly happy about it. What might be happening here? And b) on the brake assembly on that problem side, the clip had come off of the magnet. It feel out onto the ground when he pulled the drum off. And so the magnet had been floating freely and making contact with the drum all this time. There is a lot of black dust inside the drum and the magnet looks kind of bad. I'll try to upload a picture. He was able to put the magnet and clip back onto the arm, but he is not happy with it. With it reassembled, we adjusted the brakes and on the problem side are not gettting anywhere near as much braking action as we are on the non-problem side. We took it for a test drive, (I know, what was the point?) and found that when the brakes were applied hard, one side is locking up (we could hear the tire skittering on the pavement - we were going slowly) and it feels like the camper is pushing the tow vehicle to one side. Then the next day I removed the brake controller and took it for a test ride and the problem side hubs are hot. So something is still dragging in there. So I'm thinking now that we need to replace the magnet or replace the whole brake backing plate and replace the bearings. Or, just scrap the whole idea of installing brakes and put the old hubs back on and GO CAMPING. Who else is sick of this story???
