Disc Brakes

More and more people are switching their trailers over to disc brakes, and with good reason. Disc brakes deliver consistent braking - even at highway speeds - unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a substantially shorter stopping distance than drum brakes. Disc brake calipers have only one moving part, rather than the many found in drum brakes. This means that there are fewer parts to maintain, fewer parts to get damaged and fewer parts to have to repair or replace, thus reducing maintenance costs.


Over-the-Hub Rotors for Easy Replacement

Slip-on, cast iron rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.

The rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage.

Great setup. Really improved the stopping power of my 36' fifth wheel. Just completed a coast to coast trip. The extra stopping power provided additional safety and peace of mind.

  • Comparing HydraStar Disc Brake Kits with Actuator for Tandem Axle Trailers - 7K
    The only difference between the HydraStar Disc Brake Kit with Actuator for Tandem Axle Trailers - 7K part # HSE7K-T1SO and part # HSE7K-T1 is that the latter comes with the hub which is integrated into the rotor. The former does not come with a hub and is designed to be slipped over an existing hub. I recommend the integrated hub and rotor option as it easier to install and maintain.

  • Difference Between Hydrastar Brake Kits for Tandem 7k Axles HSE7K-T1 and HSE7K-T1SO
    The part # HSE7K-T1SO comes with rotors that slip over idler hubs and the # HSE7K-T1 instead comes with rotors that are integrated into hubs. So it's totally different applications based on the style of hub that the trailer has.

  • Dexter or Hydrastar Actuator Kit for Trailer with 7k Axles
    The Hydrastar actuators like what comes with the Hydrastar Disc Brake Kit part # HSE7K-S1SO are widely considered to be the most reliable and fastest reacting so this would be what I recommend. This specific kit is for a single brake axle so if you plan to have brakes on both of your axles you'd instead want the part # HSE7K-T1SO which includes the second axle as well. Then for a brake line kit the part # T4830000 would be what you'd want as well.

  • Electric Over Hydraulic Disc Brake Conversion Kit For 2017 Fuzion 371
    If you are converting from drum brakes to electric over hydraulic disc brakes for your 2017 Fuzion 371 you'll need a new hub and rotor kit, and for one that comes with the EOH actuator the correct kit is the following: - Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-T1 The # HSE7K-T1 comes with the hub-and-rotors, brakes, bearings, races, seals, EOH actuator, and brake line kit so it has all the components you need for the best...

  • Is There Slip On Style Hydrastar Disc Brake Kit for 7k Axles
    Hydrastar has a slip-on style version of their 7k disc brake kit with the part # HSE7K-T1SO. You will also need idler hubs too like with the part # AKIHUB-865-7-1-EZ-K but you should note that we don't have any oil-bath idler hubs in this capacity. So you'd have to see about sourcing an oil-bath idler hub elsewhere or use a grease hub.

  • Is 2022 Chevy Silverado 3500 OEM Brake Controller Compatible with Hydrastar Actuator
    Yes, the Hydrastar actuator included with the Hydrastar Disc Brake Kit # HSE7K-T1SO is compatible with the OEM brake controller on your 2022 Chevy Silverado 3500. There used to be an issue for the Chevy pickups where they needed the Adapter # HBA-CAM for the systems to communicate with each other properly but that was for the 2007 - 2017 model years. The 2018 and up Chevy models should work just fine according to Hydrastar.

    The difference between the Hydrastar Disc Brake Kits are the rotors they come with. The Kit # HSE7K-T1 comes with integral hub-and-rotor assemblies while the Kit # HSE7K-T1SO uses rotors that will slide onto a Idler Hub # AKIHUB-865-7-2-EZ-K.

  • Choosing Hydrastar Disc Brake Kit for 2017 Jayco North Point With 7k Axles
    It sounds like you're trying to decide between the # HSE7K-T1SO and the # HSE7K-T1 for your 2017 Jayco North Point. I recommend the # HSE7K-T1SO with the over-the-hub rotors for the cost savings. There is no real difference between the two aside from the design. Also, if something happens to a rotor you can just replace the rotor instead of the whole assembly. I'm assuming you have a hub and drum assembly on there already for your brakes so you will also need idler hubs instead. For replacement...

  • How to Determine Correct Disc Brakes
    I can tell you how to determine the correct disc brakes, but we can't do anything with a trailer VIN. So you need to know your axle capacity, bearing numbers, wheel bolt pattern, and what brake flange you have. For example, if you had 7,000 lb axles with a spindle that fit inner bearing 25580 and outer bearing 14125A, an 8 on 6-1/2" bolt pattern, and a 5-bolt brake flange you could use the DeeMaxx Disc Brakes # DE88YR. If you aren't sure what bearings you have, take apart your current...

  • 7k Slip On Disc Brake Kit that Fits Dexter Axles of
    The Hydrastar Disc Brake kit part # HSE7K-T1SO would be the correct place to start as this is a slip-on style rotor like you are wanting and comes with the best actuator out there. Then for idler hubs that would fit behind these you'd also need the part # AKIHUB-865-7-2-EZ-K and you'd be set. This will give you the slip on style disc brake kit you are wanting that fits your 7k Dexter axles and also is widely considered to be the best system around due to speed and reliability of the actuator.

  • Will Hydrastar Disc Brake Kit Work With Dexter Hub for 7k Axle
    The Dexter # 42865-KIT will work with the Hydrastar # HSE7K-T1SO. These fit 8 on 6-1/2 bolt patterns on idler hubs designed for a 7,000 lb axle. Dexter is typically considered to be the highest quality which is why they usually cost more. The # AKIHUB-865-7-2-EZ-K is designed with value in mind but they are still very well built and as far as we can tell just as reliable. This comes pre-greased and will also work with the Hydrastar Disc Brake Kit. Personally, I would go with the money...

  • Recommended EOH Slip On Brake System for a 1995 Shorlander Tandem Axle Trailer
    I took a look at that Hydrastar kit you mentioned and while we don't have an all-in-one kit like they do, we can still get you what you're looking for, it'll just be pieced together. So, for a slip on kit - the Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Stainless Steel # K2R35S will work great. These are slip on, over the hub rotors that includes two full brake assemblies, and will work with a 5 on 4 1/2" bolt pattern. For the actuator itself, the Hydrastar Electric Over Hydraulic...

  • Converting 2016 Diamond C 10k Axle Trailer and Iron Panther 7K Axle Trailer to Disc Brakes
    The D100G axles on your 2016 Diamond C trailer are 10,000 lb axles.
