Replacement Hub and Drum and Hydraulic Brakes for a Cronkite Tandem Axle Trailer

Question

Question:

I have an old Cronkite tandem axle bobcat trailer. I was told it has 3500lb axles. When I look at the assembly you sale for that set up. It does not show fee backing. The one I found 23-343 looks to be for a 7000 lb axle. The brakes measure at 12inch x 2. Just want to make sure I get the right assembly for my trailer. I need to replace all 4 brake assemblies with ? 23-342 L and 23-343 R and 1 hub with all new brakes I might pick up all new hubs too because the race is spinning in my hub 8-201. The hub I was going to get is the 8-201-5? The bearings I already purchased before I realized the hub race was bad . They are LM67048 and 25580.

Trailer hub and drum assembly # 8-201-5 does match your bearings. I am fairly certain you have 5,200 pound axles and not 3500 pound axles since all of the parts you need are for higher rated axles than 3500 pounds. The races come already pressed into the hub. If your wheels have a 6 on 5-1/2 bolt pattern then this is the hub for you.

This hub and drum takes 12 x 2 inch brakes. The brake assemblies that fit and that are also rated for 5200 pound axles are # 23-324 for the left and # 23-325 for the right. These are not free-backing brakes. If your trailer does not have a manual or electric lockout (if the trailer connector has a wire going to the back of the actuator on the trailer then it is set up for an electric lock out) then these assemblies will not allow you to easily back up the trailer up hills or over curbs. On flat terrain though just take it slow and easy and it will not be a problem.

If free-backing brakes are a must have then you could use the 7K axle assemblies # 23-342 and # 23-343 but the braking will be more aggressive and you may need to adjust the brakes accordingly.

Answer 1

Provided that your existing brakes are 12-1/4" x 4" and use the same 7-bolt mounting pattern then you can use Dexter Electric Trailer Brake Kit #23-438-439. I have included a link to a video review of this kit for you.

By definition a duo servo brake assembly will have more braking power as the servo pushes on both brake shoes. The draw back to a duo servo is that they will apply 80 percent of the braking power when in reverse whereas a single servo will only apply…

Your trailer must have free backing brakes if you have never used the surge brake actuating coupler reverse lockout. If you did not have free backing brakes, your brakes would most likely brake even if they didn't lock up when you back up because…
