There are electric over hydraulic systems that are actual pumps. They work just like electric trailer brakes, with a trailer brake controller. They build the brake pressure just like the ABS/traction control system in your does, it's capable of putting full brake pressure on electrically regardless of your foot on the brake pedal.
Electric over hydraulic is a good upgrade for boat trailers, I would assume it would work well for car dollies too.
