Difference Between Dexter DX7.5L A-60 Brake Actuators

I have an EZ Loader Boat trailer..my Atwood brake master cylinder is totally rusted and unusable..these parts are no longer available..so I am looking at Dexter DX7 5L A-60..DX.53 FR or DX.73 FR..what is the difference? thanks

Hi Bill,

So the difference between the two DX7.5L A-60 brake actuators is just that one is for trailers with disc brakes and the other is for trailers with drum brakes:

- Drum Brakes: Dexter DX7.5L A-60 Brake Actuator # DX53FR

- Disc Brakes: Dexter DX7.5L A-60 Brake Actuator # DX73FR

So you'll just want the one that is for the type of brakes you have on your boat trailer. Disc brakes require more psi from the master cylinder in the actuator than drum brakes, so that's what the internal difference is.
