Disc Brakes are Better Than Drum Brakes

More and more people are switching their trailers over to disc brakes, and with good reason. Unlike drum brakes, disc brakes deliver consistent braking, even at highway speeds. Disc brakes also offer a substantially shorter stopping distance. Disc brake calipers have only one moving part, so there are fewer parts to maintain, fewer parts to get damaged, and fewer parts to have to repair or replace.

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.



by:

Installed fairly easily, works great. Stops much faster than the old drum brakes.



by:

It's been working great for the past year. Wish I had the money to put on all of my trailers.



by:

The quality of the product was good. Everything went together and function as intended. Thanks



by:

Nice quality, fast shipment, and fairly easy installation. The brake line from the actuator to the first axle is quite long. I will go back with a custom line in the future, for now just coiled it up. William S was extremely helpful with my order.



by:

Overall a great kit. Only wish would be to use rubber lined SS adel clamps instead of the supplied plastic ones



by:

Prices, promptness of shipping and delivery, and customer service is the best I have ever done business with.



by:

Products just arrived yesterday, even though i requested packaging to be better (saw poor review comments on this before hand), it arrived in 2 large boxes that were battered to hell and opened up with contents exposed. Much to my surprise, it appears all parts are present and undamaged, going to install over weekend and will follow up with after install evaluation.



by:

Parts were shipped and received quickly, everything mounted up right and all the hardware needed was included.



by:

Thanks for quickly resolving the shipping problem!!

  • What Is The Difference Between The Hydrastar Disc Brake Kits HYD44VR and HYD74VR?
    Good question, Dale! It took me a few minutes of back and forth between the two Hydrastar disc brake kits to figure it out, but the only difference is that # HYD44VR uses all Dacromet coated parts and the # HYD74VR uses mostly Dacromet coated parts, but stainless steal calipers. Other than that, they are exactly the same. I see you ordered the full Dacromet # HYD44VR option and it will work perfectly fine with your 5th wheel. Have you done this kind of install before?

  • Parts Needed to Add Electric Brakes to ShoreLand'r Boat Trailer
    Hey Ryan! We don't have a way to identify your axle using the VIN so you will have to check and see what axle you have before we can find the right parts. I would start by checking the axle tag. It may have the capacity listed or, at least a serial number the axle manufacturer could use to identify it. If not, you will need to check and see what bearings you have. The part numbers may be stamped in the side or you can measure the inner diameter with a digital caliper # PTW80157. If you...

  • How to Determine if DeeMaxx Disc Brake Kit With EOH Actuator is Right For Trailer Axle
    Hey Guy, While I can't answer that directly as I don't know what axles you have, I can tell you how to figure out if the right kit for you is the DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers # DE66AR. What it comes down to is knowing the bearing numbers; you will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you...

  • What Disc Brake Kit do I Need for My 6,000 Pound Tandem Axle Set-Up on My Trailer?
    Hello Ed, Decided to make the swap to disc brakes, always a great idea. The # HSE7K-T1 is for 7,000 pound axles, so that is not going to work because the outer bearing will not match up to your spindle. The issue I am running into is that you chose the brake set for a 8 on 6 1/2" bolt pattern, most 6K axles have a 6 on 5 1/2" bolt pattern. I have the Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 12" Rotor # HYD44VR which will be the right bearings, but is a 6 on...
