"surge brakes are unreliable when not used every day" sounds like one of those "alternative facts"
The breaking mechanism of surge brakes is usually your usual hydraulics and pads ... the actuation is a cylinder that compresses when weight is applied to it. There's not much here that takes rocket science to run and maintain ... the fluid needs maintenance every few years and the pads can wear out but I don't know why they would need "daily use".
