In this video come along as I replace these electric brakes on this camper travel trailer and repack the wheel bearings.

was told not to jack on axle it will bed?
Good explanation how the trailer drums work Eric O very interesting design @SouthMainAutoRepairLLC
Dear Eric O., your rationale for buying the entire backing plate as a unit is remarkably sound judgement. It is akin to buying a quality remanufactured zero miles engine (did somebody say Jasper?) as opposed to a 'best of the junkyard' 65,000 mile replacement engine to replace the dead OEM engine in your otherwise serviceable vehicle. I need to do bearings, seals and brakes on my auto hauler and like you, I'm not going to skimp on the rolling parts. Thanks again!
Great info! Thank you!
cracks on bonded shoes are okay cracked on riveted shoes are not okay.
National 473336 is a DOUBLE lip spring loaded seal equivalent to 171255TB. Works with Dexter 3500# axle drums with a 1.719" ID. As always a top notch educational video.
if you are working on a Dexter axle if you notice the 8-247 cast number (this one is a 8-247-05 meaning 1/2 studs) that will tell you everything about that hub and backing plate. Rule of thumb if your backing plate needs 2 items its cheaper to use a loaded backing plate.
10” drums I believe would make them 3,500 axles. 5,200’s and 6000 come with 12”x2” iirc.
thanks Eric O – long time SMA fan who just bought a camper 😉
There are 5 or 6 different facilities in Northern Indiana that produce campers and travel trailers. They are all sweat shops! lol
Thanks for the great explanation looking to check my offroad camper brakes. Cheers Steve
I work in a RV facilities in Goshen indiana
Great information…. Like always.. anyways what is your professional opinion on placement of jack on axle? Seams in the RV world some say it's ok some say frame only… Just like your opinion… Thanks
Thanks for putting together this straight-talking educational video.
Definitely considering electric-over-hydraulic… replacing surge brakes on a trailer. Not real impressed with the electrics, thanks for the video.
Nice quick explanations. Very helpful. I'm going to watch the other parts next.
These two videos just saved me a ton of money! Thanks for sharing your knowledge. Hope you get paid back for sharing a hundred fold! 👍
You answered everyone of my questions. Thanks. I would have been bald if I thought it was just like normal breaks.
Great job! Thank you so much

How many miles does the electric magnet last. My magnets only had one dot left. I believe there is a DC short causing the magnet to engage. This is a new unit with only 10,000 miles on it. 2018 grand designs 5th wheel. unit weight 12000# empty.
Well Done…..Great Video
Ya, be careful to put the jack under the springs, not in the center of the axle. The whole backing plate with shoes, hardware, magnets, etc for both sides is the cheapest way to do the brake job. Just clean and pack the bearings, replace the seal, adjust and go!
Thanks eric just watched your video on electric brakes on a fifth wheel and feel confident enough to attempt it myself here in the uk
3 year old video still at work, just bought a car trailer and never did trailer brakes, the gift that keeps on giving. Thanks Eric O!
I always wondered how those worked. Goes to show, you learn something new just about every day. Thanks for the video.
I wish I had known this before my Dad spent $700 on tires and grease job on my Jayco. 300 of which was just for the grease job.
LOL… they make 20.00 to 30.00 per hour on the line in the trailer factories.
Is it possible to wire the brakes backwards? My wires were severed and both wires coming out of the brakes are green. Will the magnet repel if I guess wrong?
Great video
Those axles bend real easy. Jack should be close to spring if not right under it.
My trailer is 10 years old now and I probably need new brakes. No sqealing but set up is on high. Did not realize how they worked until I watched your video…….very informative and especially enjoyed your sense of humour. You did an awesome job of narrating and using the video camera, very detailed. I thoroughly enjoyed, thanks.
I have one question, what would the average shop cost be for a complete travel trailer brake job (parts and labour).
Thanks again, Lloyd
Well, the mechanism is pretty clever. I was thinking how the manage to get decent brake power from just 12V and it is taken from the drum itself.
good video never seen trailer brake repair always some thing different that`s what makes this a great channel that & what`s for lunch MRS. O TAKES GOOD CARE OF U AND KIDS lucky man
Sorta related topic i have to remove the studs of one of these similar trailers but the studs wont come out because the magnet plate is over them!? HELP please anyone!!
Awesome
Say Eric, I watched your video twice and then ordered sets of Lippert brake assemblies. Installed them and tested , just like you show in the video. one of the right brakes just gives a slight hum, and the magnet does not energize to hold my wrench. Can you give me some ideas on what may be wrong. I used a multi meter and I am getting 12.5 volts to the wires on this brake set, but no magnet energy. Is this just a bad magnet??? What do you think?
Very well done!
Dexter says that the cracking is normal and fine
when did you have time to work in a truck shop?
Love the videos…. Do you have part 2 on these trailer brakes?
I had no idea how these worked until now. Thanks for taking the time to make this video and do such a good job in explaining it in a clear and concise way.
Keep up the good work Eric
always wondered how electro magnetic brakes worked.
nice one Eric, waiting for part two and thanks for sharing.
Sweet new air impact gun. Trailer brakes, thank you for the info and thanks
for the variety.
Dude you are my star YouTube tech, no jack stand, wouldn't want you to get hurt and stop making this gold nugget videos. I would watch an I'm in a cast video tho hahah.
good ol jack…haha no fancy lift
Do you change many of these? How about the actual axles? I do probably a couple sets of axles a month, around here people overload their trailers so the axles bend and the tires burn off. I rewire brakes all the time when I repack bearings which is probably weekly.
Very cool video!!! Can't wait till the parts come in. Thanks for the video 🙂
Nice commentary on the electric brakes Eric, and looking forward to part 2.
