18” Rubber Flex Brake Hose w/ a 3/16” Male Fitting  

I do have a solution for you, but we do not carry any kits like that. Instead I recommend the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K #HSE7K-T1. If you want the Titan/Kodiak brand…

According to HydraStar, their #HSE7K-T1SO Disk Brake Kit with Actuator will take approximately 4-6 hours to install. This can vary according to how the trailer is equipped and how mechanically inclined the person completing the installation is. If…

The brake line that comes with the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Rotor - 8 on 6-1/2 - 7K #HSE7K-T1SO is a 3/16" line.

According to the fine folks at Hydrastar, any 13 inch diameter hub/rotor would work with the calipers and caliper mounting brackets. You'll want to make sure that the hub/rotor you use is compatible with the bearing set that your spindles use…

The HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers #HSE7K-T1 should fit just fine with your 7K Dexter Axles. It does sit back slightly more than what a drum brake would but unless you have a really odd-shaped axle you won't…

According to the axle tag you sent (thanks for that, BTW), you have a standard Dexter 7K axle. I'm not sure which other Hydrastar system you're speaking of. The #HSE7K-T1 kit you'd looked at is a Hydrastar complete Disc Brake Kit designed…

Disc brakes certainly work better than electric brakes, but before making that investment, I'd recommend doing some troubleshooting on your controller and the trailer brake system. A properly functioning brake controller shouldn't have much…

The Dexter #42865-KIT will work with the Hydrastar #HSE7K-T1SO. These fit 8 on 6-1/2 bolt patterns on idler hubs designed for a 7,000 lb axle. Dexter is typically considered to be the highest quality which is why they usually cost more. The…

You can use the Kodiak Ceramic Brake Pads, part #K250CP, as a replacement for the pads of the HydraStar Disc Brake Kit, part #HSE7K-T1.

I'm assuming you currently have electric brakes on your 5th wheel. The #KOD55FR, #KOD33FR, and #HSE7K-T1 you looked at will all fit your axles. Between the three, I recommend going with the Hydrastar Disc Brake Kit since it includes everything…

We can definitely get your 2019 Grand Design Solitude 2930RL set up with disc brakes, and to do so you'll need the hub-and-rotor disc brake kit, as well as an electric over hydraulic actuator. Converting to electric-over-hydraulic brakes is a…
