Hi Glenn,
The 100 psi will not make a difference regarding the 1,500 psi Dexter BrakeRite Electric Over Hydraulic Actuator for Disc Brakes # DX82KR.
Trailer disc brakes have a max operating pressure of 1,600 psi, so the 1,600 psi EOH actuators are generally rated just to meet that max pressure, but it won't matter regarding the function of the # DX82KR. This is a very nice option for an actuator, giving a much faster response time than other actuators to get optimal braking right away. view full answer...
