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 water and salt.

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.

And it looks like you are doing it all with a smile on your face Greg! Glad to hear you were prepared with the extra set of bearings as well. etrailer is lucky to have you as a neighbor (customer)! So where are you headed for the next adventure?

That doesn't looks good at all, Bob. If you run into any issues before or after install, please let me know and I can help.

The best upgrade that I could’ve made to my fifth wheel was to get rid of those drum brakes and converted over to electric over hydraulic

Glad to hear they are working better than your previous brakes, Jerry! Disc is definitely the way to go. ^___^ I will let Ashley know they are much better as well! What's the next trip you have planned to really test them out?
