Replacement Master Cylinder for Older Model Titan Model 60 Brake Actuator

Question:

Havent pulled the master cylinder off yet. Very rusted inside. Been empty for awhile. How do I know which Master Cylinder I need? Is there a part number on the master cylinder itself? Boat is a 1999 Bayliner Capri and trailer looks to be the original. Would that use the Model 60? Sheetmetal on the outside of the master cylinder says Titan. Here is a very bad pic but thats all i have at the moment. Thank you,

I spoke with my technical contact at Titan and showed him the photo that you sent in of your actuator. My contact confirmed that you actuator is a Model 60. The right replacement master cylinder for you will depend on what kind of brakes the actuator is designed for. If the brakes have never been changed out, you can determine this by checking if the trailer has disc or drum brakes.

If your actuator is designed for drum brakes, you will want the Replacement Master Cylinder Assembly # T4395100, that you referenced.

If you need the disc brake master cylinder, you will want part # T4747100.

My contact at Titan confirmed that when replacing the master cylinder on your older Model 60 actuator, you will also want to replace the strut because the new master cylinders have a bigger bore than the original master cylinder on your actuator.

Many times, when an actuator's master cylinder needs replaced, the shock will also need to be replaced. The replacement shock for Model 60 actuators is the Replacement Shock Absorber # T2336200. This shock will fit both drum and disc versions of the Model 60.

Hello!I recently purchased a used boat trailer.The drum brakes no longer work.I first tried to remove the master cylinder cap to see if it had fluid.It was seized. So I had to demo the cap to check the fluid.There was no fluid.This Actuator needs a total rebuild.My first question to start with is.Can I rebuild this actuator to work with disc brakes?Thank you

You could potentially replace just the master cylinder with one that's designed for disc brakes to provide the needed increased pressure. The availability of the right part though will depend on what brand actuator you have. If you can tell me this I will be happy to try and track down the right master cylinder, along with any other parts you might need for the re-build.
