Replacement Axle, Hubs/Drums, and Free Backing Hydraulic Brakes for a Jet Ski Trailer

Hey Greg, thanks for the information. To add free backing hydraulic drum brakes to your Jet Ski trailer, I recommend replacing your axle with the Timbren Axle-Less Trailer Suspension item # ASR2000S02.

You'll then be able to add a pair of the Easy Grease Trailer Hub/Drum Assembly item # AKHD-545-35-G-EZ-K, and the Free Backing 10' Hydraulic Trailer Brake Kit item # AKFBBRK-35. This setup works with 13" to 15" wheels so you will have to update yours.

There's no way to do what you're wanting with your current axle and here's why.

The smallest hydraulic braking hubs I have are 7" in diameter. They come in two different options depending on what size spindle your jet ski trailer has. Both have a 5 on 4-1/2" lug nut pattern and work with 12" wheels.

For a 1.063" diameter spindle that uses L44649 Bearings - Trailer Hub and Drum Assembly item # AKHD-545-2-2K

For a 1" diameter spindle that uses L44643 Bearings - Trailer Hub and Drum Assembly item # AKHD-545-2-1K

The Dexter Hydraulic Trailer Brakes item # 23-398-399 are the only options that fit the 7" hubs. They are not free backing and unfortunately no one makes free backing hydraulic brakes smaller than 10".

Please note that the 8" Hub/Rotor Kodiak Disc Brakes item # KOD27FR are the smallest disc brake rotors available. They don't make them any smaller and you already said the backspacing doesn't work.

Does your trailer currently have brakes or are you adding a complete hydraulic braking system? I'm just trying to figure out if you need an actuator and hydraulic brake lines as well. Feel free to answer this and throw in any other questions you have, where it says Add Comment.
