If your old drums are fading or hanging up, this DeeMaxx 13" disc brake kit gives you a major upgrade in stopping power and control. The 1-piece hub-and-rotor assemblies with ceramic pads and stainless steel pistons deliver smooth, responsive braking under load. Each rotor measures 13-1/8" in diameter and mounts with 5/8" wheel bolts on an 8 on 6-1/2" pattern, rated for a 7,000-lb axle. You’ll feel the difference in shorter stops and more confident control every time you tow.
Brakes take a beating when exposed to water or salt, but this kit’s Maxx coating holds up where others fail. The rotors, calipers, and brackets are coated for corrosion resistance that lasts more than 1,000 hours in salt spray testing—well beyond zinc or Dacromet finishes. Drainage holes in the hat section help water escape quickly, so the assemblies stay cleaner and resist internal rust even with repeated exposure to fresh or brackish water.
Heat buildup can lead to brake fade and uneven wear, so DeeMaxx built these rotors with vented passages and drainage holes that move air fast to keep temperatures down. The result is smoother braking on long grades and fewer pad changes over time. It’s the same engineering that helped these brakes pass the SAE J2681 automotive brake test for consistent friction performance under stress.
Swapping out your old setup is straightforward with these pre-assembled bolt-on parts. Each kit includes two integral hub-rotor assemblies with inner (25580) and outer (02475) bearings, races, grease seals, zinc-coated grease caps, 5/8" wheel bolts, and zinc lug nuts. The calipers even have laser-etched bleeding instructions right on the housing, so you can handle setup or maintenance without digging for manuals.
Built from high-quality cast iron with automotive-grade construction, this system is made to deliver dependable braking mile after mile. A full kit covers one axle and comes backed by a 7-year warranty for long-term confidence wherever you tow.

I'm here with Brian from Jonesing To Go and he has brought his well, tell us about your setup a little bit. This is a 35-foot Montana by Keystone and right now, the way it sits loaded we're about 14,000 pounds. Today, we're gonna upgrade the brakes to hydraulic disc brakes. And this is something that I've been thinking about for quite some time. And when my wife decided that she's finally ready to start pulling the rig, I knew it's time. I've waited too long.
And so right now, I gotta be honest with you I'm like a kid waiting for Christmas. I can't wait to pull this thing and hit the brakes for the first time once this is done. I've heard nothing but fantastic things about what a difference it makes. And quite honestly, you know one close call on the road is one close call too many. And unfortunately, we have those on a regular basis.
So, you know, you always hear that term white knuckle. I don't know if it's white knuckle but when you're on the brakes on the truck and your hand is on the brakes on the brake controller all the way and you're just praying you get stopped in time you know, I've had enough of that. Now we're gonna take it in the shop and get our brakes installed. We're gonna meet up with Brian later and see what he thinks after. So we got the brakes installed, we're out on the road and this is really the maiden voyage with the disc brakes on.
So Brian tows his fifth wheel quite often, so I'm kind of excited to see his reaction as he stops. So once we get to a nice little straightaway we'll jab the brakes and see what it does. So we're on just kind of a industrial straightaway here. So Brian, go ahead, hit the brakes. Wow, what a difference.
I don't think I've ever felt this thing stop like this ever. Since the day it was new. Brad And gain's set at At five. Brad What do you normally have it at Nine. Brad Well, that's good. At nine, it's never, ever braked like this, ever. In fact, there's been times I've wondered if I'm getting stopped at nine. I'm excited about not only being able to stop, but the maintenance is gonna be so much easier. Oh my God, did you feel that (Brad laughs) I hardly pressed the brake. I think he's pretty happy. Yeah. I think he's gonna enjoy these. Now speaking of braking we've actually done a little bit of tests in our parking lot and it's not exactly out on the highway testing but what we've done is we've gotten up to about 15 miles per hour in our parking lot and just used the trailer brakes at full gain and allowed the drum brakes to do what they can to stop it. Now we've gone ahead and done the exact same braking test. Now just with our DeeMaxx brakes installed. Now for a quick visual reference you can see our cone over here to my left and that's where the front of the truck was before with his drum brakes. You can kind of see where his truck is now. So obviously, it's made a huge difference. We went from 117 foot down to 53. So more than half of what we had before. Imagine that being a car on the highway and you have to make a quick movement. Instead of being there, you can be here. So we've just gone ahead and done our post disc brake installation test. What do you think about that (stutters) I'm speechless. I knew it was gonna be good, I knew it was gonna be better. I hoped it would be that, and it definitely is. I'm confident in everything we do now. I'm confident when my wife is behind the wheel towing this now. Before, I wasn't so sure 'cause she's just learning. I don't know why I didn't do it before. Absolutely, and that's really for a towing experience confidence is everything. Being able to be comfortable behind the wheel and not white knuckle makes your trip enjoyable. And the best when it comes to brakes that's definitely something to it's something you wanna put your hat on saying that you have the best brakes because without stopping, well it makes for a not so great experience. It makes a bad day if you can't stop in time. One close call is one close call too many but they're very frequent out there because even though we drive defensively and leave space between cars especially in a metropolitan area there's always that one person that cuts in hits their brakes and, you know you don't know what they're thinking or what they're doing. We can drive as defensively as we want, it's the other guy. And reaction time is everything but the fact that I have the ability to stop now means the world to me. That's awesome. Thank you so much, Brian. Thank you.
Ratings & Reviews
Best upgrade to our 5th wheel. I will do this to every trailer I ever own. The install was straight forward if you have some mechanical knowledge and experience.
Just traveled 800 miles after installing the disc brakes. Stopping distance is half of what it was. So pleased!
Excellent customer service. All of my questions were answered. All of parts arrived the very next day. Parts appear to be of high quality.
We had a rough start getting the right brakes for our Brinkley Z3100. However after ETrailer realized they made an error on the order they were right on top of it, doing everything they could do to make it right. Their people are great, kind, well informed in their products, and communicate very promptly. E Trailer will be my go to supplier for RV, and Trailer needs.
You will not be disapointed with their customer care!
Easy installation, work so much better than stock drums. Some brake pad noise under lite braking.
Angie Z was so helpful and a pleasure to work with.
Will definitely use them again.
Great Service!! Fast delivery.
The first order I made was incorrect due to my mistake, but Amy took care of it had the correct items sent out with the wrong items returned. Everything was very smooth.
Really surprised how quickly parts came. One box looked pretty rough, but all parts appear to be there. Will know more after install and put a few miles on the trailer.
The boxes arrived fully sealed, but there was significant rust on the races of two of the four hubs. I sanded the races to remove it and hopefully it won’t have long term impact. Otherwise, quality looks good and can’t wait to get them installed.
One of the kits was missing all 5 mount bolts, had to run to Hardware store to get replacements. Bolt up is simple & strait forward. Packaging needs to be more substantial as the calpers were floating around in the box & had some scuffing damage.. maybe put some composite straps around boxing so they can be easier to Carry?
Not sure if parts are correct. Brake calipers don't mount t at 3 or 9. Called etrailer they were no help. They told me to call the manufacturer.....
These seem to be great brakes and well-made and my camper stops much better now. I had originally only given the product a one-star rating because of a customer service issue and a bracket problem. But I am changing it to a five-star review because the company president called me directly and worked out the problem. Not only do they have a great product but they are willing to make things right. Great company and great product, well worth the money. The best upgrade I have done to my fifth wheel so far. If you buy the kit for the 6000lb axle, and they send you the open bracket which cannot be installed as the instruction say at the 3 and 9 o’clock positions, call the company and they will send you the correct closed brackets.
Etrailer to the rescue! Extremely high quality direct replacement for DeeMaxx EOH kit DE66AR offered on this site. Our original got damaged after a bearing failure. I actually cary a spare set of bearings which allowed us at a minimum to limp our RV home and avoid an expensive tow. Now I will replace the damaged parts.
I have towed my 16,000lb fifth wheel over 12,000mi since installing the disc brake system. The braking power and control is vastly improved with the disc brakes over the drum brakes. I am certain that I avoided a major accident because of the disc brake system. The kit had everything I needed and the customer service was great.
Have a 2024 Brinkley camper. Barley felt the drum brakes work. Camping in Colorado and the Black Hills was a little stressful with little brake help from the camper. Winter here. I've only took the camper on a test drive (20 miles) with the new disc brakes. They work awesome! All the brake power you need from the camper now.
I ordered the wrong brake kit at first. I needed 9/16" bolts instead of 1/2". Ashley from E-tailer got what I needed coming and gave ups the pickup label right after I called. Thank you Ashley!
As for the brake install. Fairly easy. Not fun, but easy. The hardest part was running and securing the brake lines. And maybe the wiring up the actuator. Instructions were great. Just a little intimidating the first time. Next time will take half the time to do. But I no plains for the next time! Also make sure your brake controller can change to elec. over hdy. Luckily my 2023 F350 did and was easy to change on the screen.
Thank you again Ashley!!
