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.

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Hydrastar Disc Brake Kit with the Electric Over Hydraulic Brake Actuator for Tandem 3,500 pound trailer axles. And these have a five on four and a half inch bolt pattern. Now this is an all inclusive kit. It'll have everything here you can see that you need to switch your trailer over to disc brakes for improved performance and greater stopping power.
You'll get four Dacromet coated disc brake end kits. So it's basically for two axles. The hub and rotor assemblies right here, they'll have half inch diameter wheel studs. And also on the inside, they pre-install the bearing races, so it makes it easier to install. Comes with all the bearings you need, the inner and outer bearings.
The grease seals are included. The calipers will come with all the brake pads installed in them, and it comes with the installation bolts. And as you can see, we've already attached them. It comes with the caliper mounting brackets. And these are designed to attach, you can see, to a four bolt brake flange on your axle.
All these parts have a Dacromet coating to 'em, which is corrosion resistant. Now the actuator right here in the middle, this is a Hydrastar Electric Over Hydraulic Brake Actuator. Basically, this will hard wire into your tow vehicle and it signals your in-cab brake controller when the brakes are applied, which will trigger the pump and motor on the actuator. So this will create a nice, smooth, even braking with a fast response time. And it is designed to work with most in-cab brake controllers.
The brake controllers, we also sell separately. The brake line kit, you can see up front here, it comes with all the solid brake lines you need, all the flexible brake lines, and all the fittings you need to install it onto your Tandem axle trailer. Now we do list the part numbers for all these products on the product page of this, if you do need to know any of the part numbers that's included. Now more and more people are switching their trailers over to disc brakes, and with good reason. It's because, unlike drum brakes, these disc brakes will deliver consistent braking, even at highway speeds. Disc brakes will also offer substantially shorter stopping distances. And the disc brake calipers, these will 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. Application, again, for this kit is Tandem axle trailers with 3,500 pound axles. Bolt pattern of five on four and a half inches. Rotor diameter of 10 inches. And the wheel stud diameter of a half an inch. But that should do it for review on the Hydrastar Disc Brake Kit with the Electric Over Hydraulic Brake Actuator for Tandem 3,500 pound trailer axles.
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.
Installed fairly easily, works great. Stops much faster than the old drum brakes.
It's been working great for the past year. Wish I had the money to put on all of my trailers.
The quality of the product was good. Everything went together and function as intended. Thanks
Thanks for quickly resolving the shipping problem!!
Parts were shipped and received quickly, everything mounted up right and all the hardware needed was included.
The items seen good quality but the problem is with Hydrastar as a company, calling out customer service, packaging and shipping departments. If it wasn't for great effort from Fred at etrailer I don't thinkl I would try working with this brand again. The packaging was so bad that the rotors ate themselves up. The studs on one rotor scared the other inside the area where the dust cap sits also ruining several studs. The exterior box was in great shape. It was all on Hydrastar. After a week of waiting Fred finally reached someone. I finally received the replacements with the same subpar boxing as before. This time with only minor scratches. Install went well until we opened the actuator box and found a smashed cap. After another two weeks we finished this two month process with success. Don't try this during camping season and not without etrailers help.
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.
Overall a great kit. Only wish would be to use rubber lined SS adel clamps instead of the supplied plastic ones
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.
The manual is pretty bad, mostly because of the wiring diagram. FORTUNATELY, the assistance from etrailer and all the install videos are very helpful!
BUT, there is a need for some videos on installing all of this on a Travel Trailer. Mine is big and heavy, hence needing this kit to start with. Wiring the actuator has been a headache and a challenge because of bad diagrams, manuals and the unique layout of a Travel Trailer vs 5th wheel. The brake parts came in good shape and are of good quality. Yes, the brake parts are hefty and need better packaging from the manufacturer. Fortunately, all arrived successfully in the end.
Prices, promptness of shipping and delivery, and customer service is the best I have ever done business with.
