Replacement Brakes System to Upgrade 2006 Sea Doo Boat Trailer

Question:

Hi!! I hope this message finds you well. I bought an old boat last year. A 2006 sea doo. The trailer I’m sure is the original. When I I’m hooked it last year I accidentally left the emergency brake line hooked to the truck when I went to pull away from the trailer. The e-brake line didn’t appear to retract. Only one wheel has the brake engaged. Not hard enough to notice while driving but, hard enough that it was smoking. With how old the trailer is, I’d like to replace everything. The hitch mount assembly, all the lines as well as the brake hub assemblies. This definitely isn’t what I do so, how to get a list of what information I need so I could buy all the parts I need would be great. As well as pointing me in the right direction for how to replace all the pieces. Thank you so much! I think it’s a UFP Model A-70

I'm happy to help with all the parts for your 2006 Sea Doo trailer. I did a little research and it appears it is a single axle trailer, for which I recommend the following parts:

-Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2HR35D
-Kodiak Hydraulic Brake Line Kit - Single Axle - 18' # 18SI-BLKIT
-Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 7,000 lbs # DM62VR

This combination is what I would use for excellent trailer brakes and an easy installation. I've attached videos and a help article to assist.

If you want to stick with drum brakes, then you would use # AKFBBRK-35-D assemblies for # AKHD-545-35-G-K hubs and then use actuator # DM72VR for drum brakes. You can use the same # 18SI-BLKIT brake line kit.

Question:

I wasn’t specific enough. I’m sorry. If I measure the diameter of the hub on the back/open side, it measures about 13” and has a 6 bolts which has, if measured correctly, a 5 1/2” bolt pattern. Sorry for the missed information. How would that affect the parts to order?

Thanks for the update. Yes, that will impact the correct parts but we can get you what you need.

I still recommend going with the brake line kit # 18SI-BLKIT and the brake actuator # DM72VR. With these parts you will use the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 12" - Left/Right Hand - 5.2K to 7K # AKFBBRK-7-D and then the Trailer Hub and Drum Assembly - 6,000-lb Axles - 12" Diameter - 6 on 5-1/2 - Galvanized # AKHD-655-6-G-K.
