Question:

Is the smaller hole in the orifice for disc or drum? I recently bought a titan 7000 lb actuator from you guys and it came with the small orifice for drum brakes. After install the brakes got hot and we had to replace the all the backing plates and try to figure it out. After i took apart a different trailer i found the orifice had the larger hole .I then realized that drum brakes must take the larger hole.

Orifice Connector # T1209800 is for drum brakes. It is the new style with 1/8" NPT threads. For disc brakes you would need # T4750300.

Drum brakes actually do not take the larger hole. Drum brakes require around 1000 psi whereas disc brakes require around 1500 to 1600 psi. The hole in the orifice through which the fluid flows is smaller on drum brake applications to limit the amount of fluid going back thus keeping the psi at the proper level.

If the problem is your brake line fitting doesn't match up to the orifice on the master cylinder you would only need an adapter fitting to go from the orifice on the master cylinder to the size brake lines you have.
