  • Parts Needed To Upgrade to Hydrualic Disc Brakes On Tandem 7,000LB Trailer Axles
    While the 12" Brakes # AKEBRK-6 are going to be sufficient for stopping your trailer the best option is to upgrade to a hydraulic set of disc brakes. The Disc Brakes will run cooler as they do not hold heat like drum brakes ensuring your brakes work when needed. The Hydrastar Disc Brake Kit # HSE7K-T1 will contain nearly everything you will need to convert to the stronger disc brakes. It includes new rotor/hubs with bearings, grease seals, calipers, brake lines, mounting hardware and a...

  • Converting from Electric Brakes to Disc Brakes on Grand Design 5th Wheel
    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 you need for a full setup. The Hydrastar comes with Dacromet-coated brake assemblies, the electric over hydraulic actuator, and the brake lines and fittings needed for your tandem axle 5th wheel. If you're using grease you will need the # F001526...

  • Disc Brake Conversion Recommendation for 2017 Keystone Laredo 357BH
    For your 2017 Keystone Laredo 357BH the best way to convert it to electric over hydraulic disc is the Hydrastar kit part # HSE7K-T1. This comes with everything needed except for oil caps for the hubs which you'd need to also get with the part # HYD27FR and you'd be set. This comes with the Hydrastar actuator which is widely considered to be the most reliable and quickest reacting actuator out there.

  • Does Oil Cap and Plug for Hydrastar Disc Brake Kit Have Torque Spec
    The Oil Cap and Plug part # HYD27FR does not have a torque spec since it's plastic. You would just need to get it nice and snug by hand with an appropriate size wrench or channel lock.

  • Can The Rubber Plug In A Hub Oil Cap Be Purchased Separately
    Unfortunately the little rubber plug for the Oil Cap and Plug # HYD27FR is not sold separately so you will need to buy the whole oil cap and plug in order to replace your missing or damaged plug. It's not a bad idea though to have an extra cap sitting around in your trailer as I've seen multiple trailers come through our shop with a broken cap from road debris or from sideswiping something or in most cases a bad gasket seal. These are really easy to crack when you're trying to take them...

  • Parts Needed For Disc Brake Conversion on 2018 Durango Gold Fifth Wheel
    Based on what I have found, your 2018 K-Z Durango Gold 5th Wheel more than likely has 7,000 lb axles. I recommend verifying this information to be sure. Assuming that is correct, I recommend the Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers # HSE7K-T1. This kit is designed for 7k axles and uses a # 25580 inner and # 14125A outer bearing. The kit includes the disc brakes, Hydrastar actuator, and a brake line kit. Grease caps are available separately. If you want to use...

  • Recommended Drum to Disc Brake Conversion Kit for 2017 Heartland RV Bighorn Fifth Wheel
    In order to convert a 2017 Heartland RV Bighorn Fifth Wheel from electric drum to hydraulic disc brakes I recommend using the Hydrastar Disc Brake Kit part # HSE7K-T1. This is a mostly complete kit that has everything you need from the disc brakes to the brake lines and actuator. The only things it does not come with are some of the smaller items like the oil cap and oil, I recommend the Oil Cap and Plug part # HYD27FR and Kodiak Synthetic Bearing Oil part # XLPROLUBE. Please note, you'll...
