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.

Integral Hub-and-Rotor Assemblies

The integral hub-and-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. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.


Kodiak calipers are constructed of stainless steel to prevent flexing and rust. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant stainless steel piston is 30 percent larger than standard pistons, ensuring shorter stopping distance and increased torque. In addition, the unique low-drag design of Kodiak's calipers allows the piston to retract farther than in most standard models, giving you a cooler-running brake.

Mounting Brackets

Designed for axles with 5-bolt brake flange configurations, the included mounting brackets are made of heavy-duty, corrosion-resistant stainless steel that is embossed to provide additional threading for guide bolts. The added thread strength ensures a tighter, more secure connection between the caliper and bracket. Another unique feature of Kodiak's brackets is the side-support angle, which guarantees that the load is carried by the bracket, rather than the bolts.

Average Customer Rating:  4.7 out of 5 stars   (6 Customer Reviews)

Trailer disc brake kit includes 2 corrosion-resistant, Dacromet-plated hub-and-rotor assemblies, as well as stainless calipers and mounting brackets. Assemblies fit 15" and larger wheels and 5,200-lb to 6,000-lb axles with 5-bolt flanges.


The calipers look great. The dacromet coating is a waste of money. Even with thorough flushing they started rusting right away. Should have spent the money and got stainless hubs . The installed bearing races were not seated completely . They did seat during the torquing procedure .


Bolted right on. It was half day job ripping the old drums off and installing these, they work flawlessly, been dipped in the ocean a few times now and no visible signs of rust yet. Sometimes I show off the effectiveness of the disc brakes to my friends. I have a 7,700lb boat and I'll only use my brake controller instead of my brake pedal going down steep hills. the trailer brakes quickly and effectively slow the GMC Yukon and boat by themselves with no vehicle brakes.
I've attached photos of the old drums I tore out and a few phases of the install as well as the entire vehicle to see what I'm talking about.
These brakes make all the difference in the world, not just because my drums were shot, but these brakes STOP on a dime.


The parts to work on any piece of trailer equipment is not readily available anywhere better than e
trailer. It is a major ordeal to find the parts you need by shopping "around". etrailer ships them
all at once


They di the job well and where sorely n eeded


My order shipped and was delivered faster than expected. The parts are top quality and the installation has gone smoothly. I am very pleased with the staff at e trailer as they were very helpful, courteous, and were genuinely concerned with my order. I definitely will order again from e trailer and will recommend them to my friends.

Thank you e trailer for your help.

PerfectNice to have safe braking while pulling my boat trailer. etrailer is definetly a safe and honest place to order from.

  • Does the Kodiak Disc Brake Assembly # K1HR526DS Come with Stainless Steel Backing Plate Brake Pads
    Yes, the brake pads that are included with the Kodiak Disc Brake Assembly # K1HR526DS have stainless steel backing plates. The reason the part # K2HR526DS is twice as much as the part # K1HR526DS that you referenced is because the part # K1HR526DS is for on ONE disc brake assembly and the part # K2HR526DS is for a pair of them, or enough to do one axle. Check out the review video I attached for more info.

  • What Parts of Kodiak Dacromet/Stainless Disc Brake Kit K2HR526DS Are Made of Stainless Steel
    The mounting brackets in Kodiak Dacromet and Stainless Disc Brake Kit # K2HR526DS are stainless steel, as are the calipers. The 1-piece hub/rotor assemblies are the Dacromet plated components. This kit works for axles rated from 5200- to 6000-lbs; an install video is linked for reference.

  • Recommended Disc Brake Coating for Twice Yearly Salt Water Exposure
    From lowest corrosion resistance to highest, the raw steel finish would offer no corrosion resistance whatsoever. E-coat, which is a cross between a painting and a plating process would offer a fair amount of corrosion resistance. Dacromet, which is a water based coating offers pretty good corrosion resistance. Stainless would offer the best. As long as you spray everything down very well after exposure, the Dacromet coated brakes would be an excellent choice for you, offering good protection...

  • Information Needed to Pick Out a Surge Disc Brake Kit for a Trailer
    We have all the parts you would need. But to pick them out we first need to know more information on your trailer. We'll need to know the bolt pattern of your wheels (see help article), the current hubs you have on your trailers bearing numbers or spindle dimensions, and the brake mounting flange style you have on the axles. With all that info we can pick out everything you would need. I attached a link to a help article that covers everything you would need and will walk you through...

  • Could Disc Brakes be Added to McClain ATT-2040 Boat Trailer
    I was able to determine that your McClain ATT-2040 trailer has UFP axles that do not come with brakes installed so the first thing you have to do is determine if you have brake flanges on your axles. I attached a picture of what the flanges look like for you to check out as well as a help article on how to add brakes to trailer axles as well. The guides will walk you through adding either electric over hydraulic disc brakes or hydraulic brakes.

  • Can Electric Brake be Used on a Boat Trailer
    Electricity and water don't mix well, but we are starting to see more boat trailer manufacturers go with electric drum brakes. As long as you unplug the brakes before backing into water you should be fine. You would also need to let the assemblies dry before reconnecting them. From the looks of the picture you submitted it looks like you have the standard 4 bolt brake mounting flange. Next you would need to measure your current drums to pick out the correct assemblies.

  • Kodiak Disk Brake Kit Recommendations for Corrosion Resistance on an Aluminum Boat Trailer
    The dacromet and stainless combination of the Kodiak Brake Kit part # K2HR526DS would work very well to fight corrosion.

  • Disc Brake Kit Recommendation for Boat Trailer with 6k Axles
    Based on what you listed as having on your trailer axle the Kodiak Disc brake kit part # K2HR526D that you listed would be the correct kit. Since you said saltwater you might be more interested in the kit that has stainless steel rotors, calipers, and mounting brackets # K2HR526DS. You'll need to swap to a disc braker compatible surge brake actuator as well though since they require higher psi ratings than drum. For that the surge brake actuator part # T4750720 would work great as it has...

  • What Would Cause Trailer Brakes to Lock Up When Trailer Wiring is Connected
    Sounds like there's a short between the 12 volt accessory circuit which is hot all the time and the brake output circuit which activates the trailer brakes when there is voltage on the circuit. Test the voltage of your 7-way on your tow vehicle with a circuit tester like part # PTW2993 on the pin in the 5:00 position. This should only have power on it when the brakes are applied. If there is voltage here the short is on the vehicle side and most likely behind the connector. If there isn't...

  • Recommended Bearing Buddy Protectors For Kodiak Disc Brake Kit
    The Hub inside diameter on the Kodiak Disc Brake Kit, part # K2HR526DS measures 2.441 inches diameter. The Bearing Buddy I recommend is part # BB2441. These are made of stainless steel internal parts and triple-chromed plated steel barrel. These also include the rubber covers.

  • Axle Recommendation For Use With Kodiak Disc Brake Kit, part # K2HR526DS
    The Kodiak Disc Brake Kit, part # K2HR526DS, will fit on a 5200 lb to 6000 lb axle with 5-bolt brake mounting flanges. This kit will require you to use 15 inch and larger wheels with a bolt pattern of 6 on 5-1/2 inches. The disc brake kit will work on a torsion axle if it has a 5-bolt brake mounting flange welded to the spindle. The brake mounting flange would be like the Redline Brake Mounting Flange, part # 4-44-1. This flange has a bolt pattern of 5 on 3/7/8 inches, which will accept...

  • Replacement Hydraulic Brakes for a 10K Boat Trailer
    Thank you for the info! I believe that you are correct and you have 2 axles with about a 5K weight rating. With that being the case it means for replacement surge brakes you need 12" brakes. If you use drum brakes then I recommend the Kit # AKFBBRK-7-D because they have a Dacromet finish that will them last longer in regards to water exposure. If you happen to have disc brakes then I recommend the Kodiak Disc Brake Kit # K2HR526DS because it uses a combination of Dacromet finish and stainless...
