If your current setup is dragging or losing bite, this DeeMaxx kit gives you a major upgrade in braking feel and reliability. The 13-1/8" slip-on rotors fit over Dexter idler hubs (008-399-05 to 008-399-08) and secure with your existing wheel bolts, so there’s no need to replace the entire hub-and-rotor assembly. Ceramic brake pads and a stainless steel piston deliver fast, responsive braking and smooth control every time you slow down.
Salt, moisture, and brackish water can destroy uncoated brakes quickly. The Maxx coating used on these rotors, calipers, and brackets has a salt spray rating over 1,000 hours—far surpassing zinc and Dacromet finishes. Drainage holes in the hat section let water escape easily and minimize internal corrosion. It’s a durable finish that helps keep your brakes working and looking good season after season.
Extended braking or downhill towing builds heat fast, which can cause fade and uneven wear. These vented rotors move air through the core to shed heat efficiently, while drainage holes enhance ventilation even more. The result is cooler-running brakes with consistent performance under heavy loads and better pad life over time.
Swapping these on is quick thanks to the slip-over design and direct-fit brackets. You’ll reuse your existing wheel bolts to hold everything in place. Each caliper comes with laser-etched instructions for bleeding the system, so you’ll always have the directions right where you need them. The kit includes assemblies for one axle—two slip-on rotors, calipers, and brackets—and works with a hydraulic actuator rated at 1,500 psi or above (sold separately).
Designed for 7,000-lb axles with a 5-bolt brake flange and 8 on 6-1/2" bolt pattern using 9/16" wheel bolts, this kit is built from high-quality automotive-grade materials for long service life. Backed by a 7-year warranty, it’s made to handle demanding conditions while delivering dependable braking every trip.

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.

The package fit my boat trailer perfectly. Installation was fairly easy and I am ver pleased with the product. thanks
Heavy duty mounting brackets and calipers. Very high quality.
Great product great service
Direct bolt on for factory trailer. The zinc coating looks like it will hold up to salt water
The cap to the brake fluid broke in shipping wondering if u can send a new one
DeeMaxx Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs came fast and well packed. Thank you
An excellent job and taking care of a problem that I had on my original shipment very impressed. Well done.
Ordering process went great!! Shipment arrived on schedule. Good experience overall
Owned the system for over a year and no rust so far. I can tell the difference in the braking power.
Now just need to install
Great brake system, starting to rust now but I dunk my trailer in saltwater 4 times a week. Thank you George J and team for quick shipping and maintaining contact even a full year after initial sale. Will be using etrailer for future purchases!
They do not come with the mounting bolts to mount the idlers to the rotors is not included, the cost is about $10 per pair. Surprised they are not included, you would think it would be turn key with all of the parts and not have to go shopping for additional mounting bolts.
They have a good quality appearance. I couldn’t figure out what the 1” rubber grommet is for..?
Fast Shipping, the brake kit is super easy to install and is working great.
I have used these brakes on a boat trailer that is used in saltwater and so far it has been working with a small amount of corrosion. I think they will be good for another couple of years but will replace with stainless steel next time.
Great jod, well done.
The parts themselves are great, but the packaging was AWFUL. A big box with two rotors in it, with loose calipers and pads banging around inside with no additional packaging material to cushion these parts. Disappointed in the etrailer customer service team, who passed the blame to the shippers. I'm sorry, but the shippers didn't package these...etrailer did.
I wasn’t sure what parts would fit my trailer so I called for information. Ashley L directed me to the correct disk brake kit which turned out to be the exact fit. A relatively easy install and now I’m back on the road again.
I did not receive the 7/16 bolts that mount the caliper bracket to the axle I would not think I would have to use the old bolts there are six or seven years old to remount the bracket which I think would be absolutely absurd. That would be like put in a rocket into space and then when it comes back not rebuild the engine and send it back up why would you do that just saying. I feel that if I bought all of that Hardware meaning the brakes and whatnot but the bolts would be included
Works great, easy to install. One improvement would be to include the hardware (bolts, nuts, washers) I had to make two trips to the hardware store. I gladly would’ve paid to have the hardware shipped with the brake set.
Very nice, wish it came with coated mounting bolts also
The calipers and brackets were original from 2018. Couldn’t get any more time out of them due to corrosion. I have coded the new ones with Cora seal and a few coats of zinc and rust oleum hoping I will be able to get a few more years out of them only time will tell.
Having electric brakes compared to Electric over Hydraulic disk brakes is no comparison at all. I’m so pleased with our DeeMaxx brakes that I can’t believe regular brakes are still allowed. They surely are not safer and they are not cost effective. I may need brake pads soon, but that’s a good thing all I have to change are the pads, not the total braking mechanism like you have to do with the conventional systems. Anyone thinking of converting, it’s worth every penny. I’m now considering independent suspension.
The other part of that purchase is etrailer, its expert support personnel and experience is second to none. Ms. Bay helped me make sure I got everything I needed. She is an outstanding representative of the larger company, also outstanding, etrailer. It will always be my first stop because of Ms Bay. Happy New Years to you all.
Installed these on 2 customer trailers and they are nice kits but... the caliper bolts back out as the factory installed Loctite doesn't hold. Contacted DeeMaxx and they refused warranty even though they admit they have had numerous problems. Have not had issues since cleaning the blue Loctite off and installing red. (and replacing all the damaged components)
