Brakes Locking Up On Tandem Boat Trailer With Hydraulic Drum Brakes  


I have a 2002 Magic Tilt Trailer, tandem axle with 14inch tires, Titan hydraulic drum surge brakes and a Titan Model 60 Actuator, the GVWR is 6000 lbs and the GAWR is 3420 lbs. The brakes are only on one axle, mounted on the front axle. I purchased this trailer new and it has operated fine, with the only exception that the tires skid when I apply the brakes. I have several questions: 1. What will eliminate the tire skid when applying the brakes? Moving the brakes to the rear axle? Adding another set of brakes to the rear axle? 2. I recently took a trip fishing in salt water. 1st time. The brakes locked up after being in the salt. There was no corrosion and I have completed torn down the brakes and they look fine. Maybe a caliper replacement or simple adjustment needed? 3. Can you recommend the parts needed to replace my existing drum brakes to disc brakes? Can I use the existing actuator or does it need replacing, as well? thanks in advance

I would love to sell you a complete system but I think that it may be simpler to take care of the problem. Since you said you have taken the brakes apart and find no issues, the problem may be in the actuator. The master cylinder could be the problem, causing it to send too much fluid to the system. The replacement master cylinder assembly for Titan Model 60 Actuator is part # T4395100. This kit includes the master cylinder, filler cap, orifice fitting and hardware needed.

If you find the actuator is working okay, then you may need to simply adjust the brakes.

I have attached a link to a helpful article that explains what is needed if you decide to add disc brakes to your trailer. You will need to change out your actuator, and add the brake line kit to the second axle as well.

You will need to make certain the second axle has the brake mounting flange already in place. I would recommend a welder with experience in trailer building for this installation. I do not recommend this installation for a person inexperienced in trailer building and repair. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle can occur.

I have also attached a video that shows how to change out brakes, bleed the system, and adjust them as well.

I have also attached a link to our product page for disc brakes you can check out.
