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. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.

This is a great upgrade to any large trailer. I have a 44’ toy hauler, w/ triple Lippert 7000lb axles. We’ll worth the $$. Took me about 12 hrs to install.
by: Robert06/05/2022
Hello we have a triaxle 45' Toater trailer combination we use for racing. Total rolling loaded weight is 46k. The trailer was equipped from factory with electro magnetic brakes that in combination with the air brakes on the truck using digital controller was very ineffective ! WE installed these and it now stops like your car ... VERY VERY good solution ! we had one clearance problem with the top caliper bolt and the inner finder that was easily modified for clearance. This solution is a effective easy to install and it improved my trailer stopping power 100% ... also you will need a double flair tool for a clean instillation
by: Larry03/02/2021
Finally installed after snow fell, Did not use supplied bearings as they were shipped loose in a plastic bag and not wrapped up and individually boxed as when you buy from a bearing supplier, so I purchased new timkin taper bearings and installed them instead. Bleeding the system was simple enough, now I just have to wait till spring to road test system.

Disappointed in how this item was packaged and shipped. You can’t ship stuff out in a box of 108 lbs with ups, what are these people thinking in the shipping department.
