You are not the first neighbor to inquire about a replacement master cylinder for the Dexter DX7.5 Drop-N-Go Brake Actuator - Drum Brakes # 099-175-00. While we do have the # 099-175-00, replacement parts like the master cylinder kit are not available for this model. With that being said, the only option is to completely replace the # 099-175-00.

The best solution we have is going to be a new surge coupler like the #099-175-00. Some of the Dico and Titan parts are interchangeable in recent years but since your trailer is almost 30 years old it's tough to say what all would still work.…
