Difference Between Model 60 Surge Trailer Brake Actuators that Fit Disc and Drum Brakes


It says disc brakes, but can it be used on either disc or drum brakes? Thank you.


Expert Reply:

Trailer drum and disc brakes require different psi ratings so that's why the part # 099-175-20 can only be used on disc brakes. Drums usually need 1,000 psi whereas disc needs 1,600 psi.

For a version of this coupler that is designed for drum brakes you'd want the part # 099-175-00.

Or you can change out the master cylinders to fit the application. For a Model 60 actuator like this the part # T4820000 is for disc and part # T4395100 is for drum. To convert either actuator would only take swapping out to either master cylinder.
