Do Duo Servo Brake Assemblies Have More Braking Power than Single Servo

Question:

In hydraulic brakes size 12 x2 Im asking if there is much braking performance difference between the uni- servo type versus the dual servo please. Thanks.

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 20 percent which will make reversing your trailer easier.

The most important thing you should do is get assemblies that are properly rated for your setup. If the assemblies are rated properly for your trailer I guarantee they will perform great regardless of servo design.

Once you know the capacity of your axles check out the link I attached to the right that has all of the 12x2 hydraulic assemblies we carry. With that info you can pick out the correct assemblies.
