If your old drum brakes are dragging or worn out, this 13" DeeMaxx Disc Brake Kit is a big upgrade. The one-piece hub-and-rotor assemblies deliver smoother, more controlled stops and require little maintenance thanks to the simple disc design. Each kit includes two Maxx coat hub-rotors, stainless steel calipers, and all necessary bearings, races, seals, and hardware to outfit one axle. With a 7,000-lb axle capacity and 8 on 6-1/2" bolt pattern with 9/16" wheel bolts, it’s built for real stopping power.
Saltwater and road salt can destroy ordinary brakes fast. DeeMaxx uses a Maxx coat finish that survives over 1,000 hours in continuous salt spray testing—far beyond zinc or Dacromet coatings. Stainless steel calipers and pistons resist rust completely, while drainage holes in the rotor hat help moisture escape. Together they keep the brakes clean, smooth, and reliable even after exposure to wet or salty conditions.
Heat buildup is one of the biggest causes of brake fade. The vented rotor design moves air through the core to shed heat quickly, while added drainage holes give even more ventilation than standard rotors. That means cooler operation on long grades and less wear on pads. The result is steady braking control under load and longer service life for the whole system.
Installing these brakes is straightforward thanks to the integrated hub-and-rotor assembly—no extra steps to align or clean separate pieces. The caliper brackets use a side-support design that reduces bolt wear, and the calipers have laser-etched instructions right on the back for bleeding the system when it’s time for maintenance. Ceramic pads give quick response and smooth braking without constant adjustment.
DeeMaxx builds these hub-rotor assemblies from durable, automotive-grade materials proven to pass the SAE J2681 friction test for performance. Each assembly includes preinstalled bearings (25580 inner and 02475 outer), races (25520 inner and 02420 outer), grease seals (GS-2250DL), zinc grease caps, and lug nuts—all backed by a 7-year warranty for lasting confidence every time 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.

Thanks for sharing that, that’s a really important detail to call out. On setups like this, the included studs are typically sized for standard steel wheels, so when switching over to thicker aluminum wheels, it can definitely lead to needing longer studs like you ran into. I can see how that would be a frustrating surprise in the middle of an install. Glad you caught it and are getting it sorted out. Once everything is buttoned up, we’d be interested to hear how the full setup performs for you. What kind of trailer are you running these on?

Hey Steve! Thanks for the kind words and the detailed response! Sounds like you found exactly what you needed for your boat trailer. Was that your first time installing a brake setup like this? How was the install?
