Video Transcript for HydraStar Hydraulic Brake Line Kit Review

Speaker 1: Today we're gonna be taking a look at HydraStar's Hydraulic Brake Line Kit for Tandem Axles. You can get these with a 30 foot long main line with part number HS496-252, or a 15 foot long main line with part number HS496-152.The brake line kit is gonna include one long line, a six foot long to go from one side of the axle to the opposite side, and two four and a quarter foot long brake lines to go from your front axle to your back axle. This is also gonna come with four 3/16" flex lines to connect to your brake calipers. And you're gonna get all the union and hardwares you need to connect it.The brake lines are make of a durable, corrosion resistant copper nickel alloy. The flexible liens have a kink-proof design, and they're great for foldaway trailer tongues.Now on our 5th wheel here, we've mounted our brake actuator here inside our front compartment. Our brake line attaches to the back side.

I went ahead and drilled a hole in the bottom of the compartment and ran the brake line down through the hole.To ensure that we bend our brake lines properly without causing any kinks in the line, we're using a special tool for bending those brake lines. You can pick up these tools at your local automotive store.And then we began routing it back towards our axles. Our longest line finished its point here at our axle on our passenger side. We used the four-way union to connect one brake hose to the wheel right here. We used the medium sized line to run across our axle.

And we used one of the two short lines to go from this axle to the axle right behind it.The line that routed across to our driver side we connected here to the three-way union. One brake hose connects to that, and the other end of the three-way will go back towards the axle and the rear using that short line, again we have two of these short lines. The other end of our short lines will go to a straight union that'll connect the line to the brake hose.And now I wanna tighten them down using a 3/8" line wrench, which is available here at etrailer.com, and a half inch wrench just to hold your union fitting in place while you're tightening it down. Our brake hose hooks up on the backside here. Now, you can bleed the breaks and you're all set.And that completes our look at HydraStar's Hydraulic Brake Line Kit for Tandem Axles..

I recently ordered a complete hydraulic disc brake kit for my horse trailer, as I wanted to change out the worn out electric drum brakes with something better. I worked with Carla on getting all of the right parts to make this changeover. She was very helpful and made sure that I got all of the necessary parts on order. I received everything in one shipment and set out to install the brake kits on all four wheels. I ran into a problem with the brake line kit that was supplied by HydraStar...they didn't include the brake lines and fittings for the second axle as was specified in my order, so I had to make a special run to my local auto parts house to get the lines and fitting at an additional cost. I placed a call to eTrailer to let them know what happened and they said that they would have a tech from HydraStar give me a call. NEVER GOT A CALL FROM THEM!!!!!! Anyway, the installation proceeded and all went smoothly after that. It took me two and a half days to do this entire installation myself and I am very happy with the results. I just got back from a 2000 mile trip with the trailer and everything worked perfectly. Thank you Carla and eTrailer for your help and providing good quality products. 314641

  • Parts Needed to Convert Trailer from Electric Drum to Electric-Over-Hydraulic Drum Brakes
  • To convert your gooseneck trailer from electric drum brakes to EOH (electric over hydraulic) brakes you'll need a few items, all of which are detailed in the linked article on adding an EOH braking system to a trailer. These include the hydraulic brake assemblies, the hub/drums you have, an EOH actuator like the HydraStar # HBA-12, a brake line kit, emergency breakaway kit and a compatible trailer brake controller that will work with an EOH actuator. Not all trailer brake controllers...

  • Recommended Parts To Convert Electric Drum Brakes To Electric-Over-Hydraulic Disc Brakes
  • To convert your electric drum brakes to electric over hydraulic disc brakes, you will need disc brake assemblies, a brake line kit and an electric over hydraulic actuator. The disc brake kit I recommend with an 8 on 6-1/2 inch bolt pattern and fit on your 7,000-lb axles I recommend part # K2HR712E. This kit has an e-coat finish to help prevent corrosion. This kit comes with 2 hub/rotor assemblies, to convert 1 trailer axle. If you are using brakes on both axles you will need 2 kits....

  • Electric Over Hydraulic Brakes, Leaf Springs, Bearings, Hardware, & Brake Lines for Dexter 7K Axles
  • Since the ProLube kit # XLPROLUBE2440KIT is only rated for use on 5,200 to 6,000 pound axles I do not recommend using it for 7,000 pound axles. Grease would be better for marine applications since a hub full of grease repels water and an oil bath hub could just let the water set on top. The correct grease seal for disc brake kit # K2HR712D is # RG06-070. It does have an inner diameter of 2.25 inches and the outer diameter at 3.376 inches will fit the hub in the disc brake kit.

  • Disc Brake Conversion On 5th Wheel With Tandem 4400 lb Axles
  • We don't carry a kit compatible with the 4400 lb axles. We have 3500 lb assemblies that will fit your axles, but that will lower your capacity and will require new wheels because they are only compatible with 5 on 4-1/2 bolt pattern. If you choose to go this route, I recommend the Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet and Stainless - 3,500 lbs # K2HR35DS. The brake flange may require customized mounting because you have the 4400 lb axle. We will also need...

  • Recommended Hydraulic Disc Brakes for Dexter 7,000 Pound Axles
  • For the 7,000 pound Dexter axles on your 5th Wheel Camper, I recommend the Kodiak Disc Brake Kit # K2HR79E. This kit is designed for 7,000 pound axles, 16 inch and larger wheels and features an 8 on 6-1/2 inch bolt pattern. The kit includes 2 full brake assemblies (rotor-and-hub assemblies, cast iron calipers, caliper-mounting brackets and caliper-mounting bolts). You will just need to add the compatible bearings with # 25580 and # 02475 and for the grease seal # RG06-070. Then for...

  • Installing Hydraulic Disc Brakes on a 5th Wheel Trailer
  • I can help you correctly run hydraulic lines on your trailer. Adding disc brakes is a great idea, but the reason you are having such difficulty finding a schematic is because hydraulic brakes are rarely installed on 5th wheel trailers and they are typically installation specific. I have made a diagram of a typical setup on a trailer for you to look at. In this diagram I have run the main line down the driver's side frame of the trailer so the shorter lines are needed to the driver's...

  • Parts Needed For Converting 5th Wheel Trailer With Tandem Axles To Disc Brakes
  • We have just what you need to convert to disc brakes on your fifth wheel trailer. First, I recommend the Kodiak Disc Brake Kit, part # K2HR526D. This is for one axle so for a tandem trailer you will need to order 2 kits. This kit has a 6 on 5-1/2 bolt pattern. The inner bearing has a 1.750 inner diameter and the outer bearing has an inner diameter of 1.250 inches. For a brake line kit I recommend part # HS496-152 for a 15-ft kit, and part # HS496-252 for a 25-ft kit. These are designed...

  • Recommended Electric Over Hydraulic Brake Set Up for 2016 Montana 3710FL 5th Wheel
  • I was able to confirm that your Montana 3710FL uses tandem 7000 lb axles. A 7K axle would typically have an 8 on 6-1/2 wheel bolt pattern and the spindles would be compatible with a 25580 inner and an 14125A outer bearing. You'll want to identify the inner and outer wheel bearings used by your current hub/drums. Let me know if your hubs uses a different outer bearing. If your drums use the 25580 inner and 14125A outer bearing, I'd recommend the Kodiak 13 Inch Hub/Rotor Kit, part # K2HR712E....

  • Brake Line Kit Recommendation for Use with HydraStar Actuator part # HBA16
  • The HydraStar Actuator part # HBA16 that you referenced has a kit specifically designed for it that includes a 1/4 inch feed line. For that you'd want the HydraStar kit part # HS496-252 which comes with a 30 foot long feet line.

  • Switching My Electric Drum Brakes to Hydraulic Drum Brakes on Dexter 10k Axles
  • We carry disc brake kits for the Dexter 10K Standard Duty axle. Unfortunately, there is no disc brake kit available through our venders that fits the Dexter 10K Heavy Duty Axle. You could upgrade to a hydraulic drum brake system from your electric drum brakes. You will need Dexter Left Hand Hydraulic Brake Assembly # 23-404 and the Right Hand Brake Assembly # 23-405. If your drums need to be replaced, you will need Brake Drum Assembly # 9-27-1. You can remove your hubs off your current...

  • Recommended Trailer Braking System For 30 Foot Pontoon Trailer With Tandem Axle
  • With a 6000 lb capacity on your pontoon trailer and 13 inch wheels, you most likely have 3500 lb axles. For this, you will want Electric Trailer Brake Assembly - Self-Adjusting - 10" - Right Hand - 3,500 lbs # AKEBRK-35R-SA and the left side assembly # AKEBRK-35L-SA. The mounting hardware kit is # BIK-00. You will want to run 10 gauge wire to these brake assemblies and it can be purchased by the foot # 10-2-1. To finish your wiring, I recommend the Epicord 7-Way Molded Trailer Plug...

  • Best Parts Needed to Convert Dexter 7,000 lb Trailer Axles to Electric Over Hydraulic Disc
  • For your Dexter 7k Axles we have the Dexter disc brake kit part # K71-694-695-10 which comes with the brake and hub parts for both sides of the axle. Then for a kit that includes the actuator, breakaway, 7-way kit and juntion box you'd want the part # HS381-9067. For a tandem axle brake line kit that's 30 feet long for the main line we have the part # HS496-252. You will need a brake controller that is compatible with this style of brakes. For that the best option is the Prodigy P3...

  • Is Larger Diameter Brake Line Required when Switching from Drum to Disc Trailer Brakes
  • You would only need to switch to a larger diameter brake line if the braking response was slow. You can go to a larger line if you wanted but it won't be necessary. We have 1/4 line kits such as # HS496-251 for single axle trailers, # HS496-252 for tandem axle trailers, or # HS496-253 for triple axle trailers.

  • Parts Needed to Convert Tandem Trailer to EOH Disc Brakes
  • As long as the brake controller in your 2014 Dodge Ram pickup has a setting for electric-over-hydraulic (EOH) brakes then it should be able to work properly after you convert your tandem axcle 5th wheel trailer to EOH disk brakes. Aftermarket controllers like the Prodigy P2 # 90885 and P3 # 90195 offer the flexibility to work with either electric or EOH braking systems simply by selecting that option from their menu screens.

  • Parts Needed to Convert from Electric Brakes to Electric Over Hydraulic Disc Brakes
  • To convert your trailer from electric drum brakes to electric over hydraulic disc brakes we can start with the disc brake kit. Since you have 7,000 lb axles a great option is the Kodiak Disc Brake Kit # K2HR712D (one per axle) along with Bearing Kit # BK3-200. To ensure this kit is going to work you will need to ensure you have a 5-bolt brake mounting flange and what hubs you currently have. You will need to take apart your current hub assembly and look at the bearings themselves; wipe...

  • Troubleshooting HydraStar Electric Over Hydraulic Actuator for Drum Brakes
  • I was unable to find an order number for you so I don't know the exact set up you used to install the HydraStar Electric Over Hydraulic Actuator for Drum Brakes - 1,000 psi # HBA-10, but the issue doesn't seem to be the Tekonsha Prodigy P2 Trailer Brake Controller # 90885. The issue is almost certainly the wiring or brake lines you are using, and it is strongly recommend you use 10 gauge wire # 10-1-1 for the power lead of the actuator. Additionally, your brake links may be too small...

  • Recommendation on Switching Vacuum Over Hydraulic Brakes to Electric Over Hydraulic Brakes
  • Since the braking power is still hydraulic, you should have no issues converting from a vacuum over hydraulic system to an electric over hydraulic (EOH) system. The electric over hydraulic actuator will take the place of the vacuum that pressurized the existing brakes. Now, since you have disc brakes already installed on your trailer, I recommend the HydraStar Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi, # HBA16. The HydraStar actuator will allow you to apply the brakes...

  • Adding Electric Over Hydraulic Disk Brakes to a 5th Wheel Trailer with Electric Brakes
  • A disc brake set up will need to be pieced together since your trailer has 7K axles. All of the kits only fit 3500 pound axles. The only option that is close to what you are looking for looks like kit # K2HR79DS (one kit per axle) and would be the best option. But with it the calipers are stainless and the rotors are dacromet. There isn't a stainless steel rotor for this application. For this kit you would also need bearing kit # BK3-200 (one needed per hub). For an electric over...

  • Axle Ratings and Parts Needed to Convert to Disc Brakes for Trailer with Tandem 7,000 Pound Axles
  • As long as there is nothing wrong with your current axles there is no need to replace them. If your concern is because combined their capacity only equals 14,000 pounds that's not a problem because you have to keep in mind that part of the trailer's weight will be on the hitch. One of our most popular disc brake kits is the Kodiak # K2HR79E. It's for 7,000 pound axles, like yours and has a 8 on 6-1/2 bolt pattern. For the brake lines you can use # HS496-252.

In order to do this you are going to need disc brake assemblies, trailer hubs, brake lines, and an electric over hydraulic actuator. For the disc brake assemblies you will want to use the Kodiak Disc Brakes part # K2R1058D11DAC. You will need one kit per axle. For the trailer hubs you will want to use the Dexter Trailer Idler Hub Assembly...

  • Parts Needed to Convert Trailer with 8k Electric Brakes to 8k Electric Over Hydraulic Brakes
  • Converting from electric drum brakes to electric over hydraulic drum is pretty straight-forward. Basically you swap out the electric brake assemblies for hydaulic ones, you run hydraulic lines and then install an actuator and you'd be all set. For hydraulic brake assemblies you'd want the Dexter Hydraulic Drum Brake Set part # 23-410-411 which is a set that includes one passenger side assembly and one driver side. The actuator kit then to go with is the Hydrastar kit part # HBA-12...

  • Parts Needed to Add Electric-Over-Hydraulic Disc Brakes to a 2019 Grand Design Solitude 375RES
  • To replace the electric brakes on your 2019 Grand Design Solitude 375RES you will first need disc brakes. For your 7K axles I highly recommend the Kodiak Disc Brake Kit # K2HR712DS because it has a dacromet coating and stainless steel calipers which gives them great corrosion resistance. The kit includes enough parts for brakes on 1 axle so you will need 2 of them. For brake lines I recommend the HydraStar Hydraulic Brake Line Kit # HS496-252 which gives you a steel main line but then...
