Master Cylinder Needed for the Titan Model 20 Actuator for Drum Brakes with Drop # T4042700  

We do have the Titan master cylinder replacement part #DX66FR which has the number 23744 stamped on the side of it. See attached picture. A lock out solenoid would attach directly to the back of the master cylinder without an adapter. If you are in…

I spoke with my contact at Dexter, and the #DX66FR master cylinder does include the boot and push rod, but their design does not require the gasket. Please note that this master cylinder is a replacement part only for the Titan brand Model 10 and…

Look at the side of the master cylinder and you'll be able to tell which type of brakes it is designed for by the number. If you see 23744 stamped into the side of it you have a drum brake model. If you have 25744 stamped in the side…

I verified that the distance between the mounting holes center to center on the Master Cylinder for Titan Actuators, #DX66FR, is 3-7/16 inches. This master cylinder is designed to fit Models 10 and 20 Titan Actuators with drum brakes. If the holes…

To convert your Model 20 actuator to work with disc brakes only requires the master cylinder to be changed to the part #T4749501042. Then for an electric reverse lock out solenoid all you need is the part #T4748800 and your set.

It sounds like your boat trailer that has surge brakes that are locking up in reverse. This is a fairly common scenario that has an easy fix. With surge brakes, you have a brake actuator applying the needed pressure to the brakes but to be able to…

The difference between a disc brake master cylinder and a drum brake master cylinder is a small check valve that is inside of a drum master cylinder but not present in a disc one. Disc brakes require more pressure than drum brakes so there is no…
