Hello, neighbors, it's Brad here at etrailer and today we're taking a look and installing the DeeMaxx disc brakes for 7,000 pound axles with 13 inch rotors on a 2020 Keystone Montana. Now what kind of sets these apart is definitely gonna be the rotor design and you're gonna notice right away we have these holes here on our hat of the rotor and what makes that a little bit more unique than your typical one is not only is it gonna cool because that heat is gonna be able to kind of dissipate through those holes, but also it's really important for anyone that does any marine usage of their trailer, or even driving in inclement weather where water kind of gets caught in the backside of this, and the problem with other rotors is that water just kind of spins around, and as you park, it's gonna sit at the bottom and if you park your trailer for a while, that's gonna eat away at that rotor and this actually allows it for it to drain out. Another great part about this is when they're able to put the coating on the rotor, it gets nice and uniform, there's no drip marks, so again, you get a little bit more uniformity and overall better quality. Now what also sets these apart and really comes down to being heavy duty is gonna be a robust caliper design. It's 28% thicker than your standard calipers out there and it's gonna promote a little bit more even pad wear. It also prevents the caliper from splitting.

So over time these can kind of get thin here and when that cracks, well, there goes your brakes. And many times with other brakes, you are kind of left with only a few different ways to mount up where your caliper's gonna go and you can see there's plenty of holes available. You can really mount this in a number of different ways, so for clearance issues, that makes it nice and easy. You also have tube bleed screws so you're able to bleed it from a number of different locations, so you're able to do that at 120 degrees, whereas normally when you're bleeding, you're stuck with 90 degrees and that's just gonna kind of limit you and just make it a little bit more tricky as far as getting these installed. So here on our caliper you can see our two bleed screws here.

What's really nice too is they've laser etched on the back here to let you know that you have both of these able to bleed, but also they give you the torque settings for when putting your caliper bolts in place so that's really nice if you do take these off and you go, oh, I forget the torque setting, no problem, it's on here and that's really just kind of goes to the quality of their products. They've really taking a lot of time to make sure that there's quality in every step of the way and that even goes to your brass fitting here. It's quite a bit thicker than some of the other ones you've seen and you're able to actually get a wrench on here if you have to rotate it and not really worry about cracking it. Some of your other brass fittings you gotta be real careful 'cause that can snap. This one's definitely a little bit more robust.

These will come standard with Kevlar brake pads. Having Kevlar means that you're gonna have much longer life, and also the design of the brake pads is really nice too because you have these metal dowels here as well as a kind of unique clip here and that just really makes sure that these aren't gonna be popping out any time, so with that pressure against the rotor it really does just kind of keep this in place. You can see once we have this snapped in, those are gonna keep these nice and aligned. The internal seals on our brake piston are going to be EPD and rubber, which is definitely made for holding up to a lot of high temperatures, as well as cold temperatures, and it is really great stuff. It's made in the US and that's gonna really prolong the life of the piston and really the main moving mechanism of your brake so that means that your caliper you shouldn't have to replace for a long time.

Now your dust boot here on your grease cap is gonna be made of silicone. This can be exposed to UV and it's not gonna break down over time as we've seen some of the other rubbers that they use will start to get brittle and crack and then you have grease coming out of them. Now here we have an integrated hub and rotor one-piece assembly, which is really nice. It's gonna keep any uneven wear on the rotor down to a minim
