OK but needed to make a field modification to make the brakes more serviceable in the future. 275586

Provided the plumbing needed. The kit could use a few more of the metal tubing "holders" that screw the trailer, at least for my project I need about 6 more to hold the tubing securely. 206028

Ask the Experts about this Demco Accessories and Parts

  • Brake Line Kit that Includes 19 Foot Steel Line for Disc Trailer Brakes on a Boat Trailer
    You could use Titan brake line kit # T4829900 instead. It comes with a 19 foot long steel line. Normally if brakes are only going onto one axle of a tandem axle trailer they go on the front axle, not the back axle. That is likely why so many kits only have a 16 foot line. You get better braking when the brakes are on the forward axle.

  • Selecting a Brake Line Kit for Boat Trailer Being Converted to Disc Brakes
    You are correct to place your disc brakes on the rear axle of your boat trailer since this is where most of the weight will be carried (nearer to the boat's motor). Disc brake and torsion axle applications both require flexible brake lines so yes you can use the kit you referenced, part # DM5424. This kit includes 18-7/8-inch long flexible lines, but if your measurement shows you need longer flex lines we offer various sizes of lines; part # T0777300 is 13-inches; part # T0776500 is...

  • Can Kodiak Disc Brake Kit # K2R35D Replace Idler Hubs on Demco Tow Dolly
    Thank you for including a photo of your idler hubs. The Kodiak Disc Brake Kit you referenced, part # K2R35D, requires a standard 4-bolt brake mounting flange in order to mount. The standard 4-bolt square mounting flange that this kit will fit, part # 4-35, is shown in the linked photo which includes measurements of the hole spacing. We do not recommend drilling your existing flanges; it is better to have a qualified welder replace them with the correct ones. Your existing hub appears to...

  • Recommended Disc Brake Components For Demco Kar Kaddy Tow Dolly
    For your Demco Kar Kaddy, the Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 6,000 lbs # DM8605101 will work great. The Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2R35D will not work well with the brake flange so you will want to upgrade the flange to the # 4-35 since the Kar Kaddy has a unique flange instead of the standard. The idler hubs # DM04369 will work well without any modifications. Then you will just need brake lines...

  • Aluminum Car Trailer Restoration and Replacement Brake Recommendations
    Thanks for the feedback, and I am glad that you are finding our website helpful! For your 1989 Trailex CT-7031 all aluminum trailer with the specifications that you provided there are three options for restoring or replacing the brakes for this trailer. The three options are similar to what you mentioned, and are: 1.Hydraulic Drum, which is the most cost effective. 2.Hydraulic Disc, which is more expensive, but provides better performance. 3.Electric drum, which is most cost effective...

  • Compatibility of Kodiak # K2R526DS Disc Trailer Brake Kit with New EZ-Loader Axle
    As long as your new axle has a 5-bolt brake mounting flange, the Kodiak # K2R526DS should work fine for you. You'll also need a brake line kit like part # DM5424 and an actuating coupler like part # 099-175-20 for a 2 inch trailer ball. I've linked you to an FAQ article that shows everything you'll need to think about when you're adding hydraulic disc brakes to a trailer.

  • Hydrastar Electric Over Hydraulic Brake Kit Recommendation with Single Axle Brake Lines
    Since you have a single brake axle your best option would be to go with the HydraStar EOH Kit part # HS381-9067 which includes everything but the brake lines and then from there use the from Demco # DM5424 to supply the single axle line kit.

  • Everything Needed to Install Electric Over Hydraulic Disc Brakes on Trailer with 3,500 lb Axle
    I can help you pick out the parts you would need and make it as simple as possible, but there isn't a single axle electric over hydraulic kit that includes everything. You would want to start the part # HS381-9067 which comes with the nicest actuator around, a breakaway kit, junction box and the needed wiring. For the brake components you would want the part # K2R35D for a 3,500 lb kit unless the trailer will be seeing saltwater. In that case you would want the # K2R35S instead. For...

  • Single Axle Brake Line Kit Needed for Triple Axle Trailer to Make a Triple Axle Disc Brake Kit
    You wouldn't need a triple axle brake line kit, # HS496-253, because the Titan Disc Brake Kit # T4843800 already comes with 2/3 of what you need. So you would need a single axle kit # DM5424 or # DM5425.

  • Brake Line for Hydraulic Disc Trailer Brakes on a Single Axle Trailer
    Brake line kit # 9504 is one that we have listed for drum brake applications which have a lower psi rating than disc brakes. What I recommend is # DM5424 that works with drum or disc brakes. This means that the lines are rated for at least 1600 psi which is typical disc brake pressure. Quarter inch line is not available. If you need 1/4 inch steel line then most auto parts stores carry various kinds of brake line and you could inquire about diameter availability.
