I have a 2000 single axle dorsey trailer with drum brakes. It has the UFP sliding actuator. Does anyone know what DOT Fluid Dorsey used. Thanks.

I use Dot 3/4 Valvoline Synthetic....

Every trailer uses DOT 3. DOT 4 won't work any better, but theoretically won't absorb water. Who knows? Considering how cheap brake fluid is, it's not a difficult decision to flush the trailer brake lines at the end of each season to remove any water.
