1. An improved trailer mounted braking system to pressurize a brake system upon detection of deceleration to provide a faster response time when operator brake pressure is applied, said braking system comprising:
a trailer formed from a frame having a predetermined mass, said frame having a tongue section leading to bifurcated rails on a rear section with an axle coupled to each rail, said axle having a wheel and hydraulically operated brake rotatably coupled to each end of said axle;
a surge component coupled to said tongue section, said surge component having a sliding coupler housing a forward and rearward spring retainer securing a rubber spring and spring spacer by use of a spring guide pretension bolt extending therethrough;
a trailer coupler having a first end secured to said surge component and a second end available for securement to a towing vehicle;
a controller attached to said surge component, said controller coupled to a magnetic sensor for calculating vehicle deceleration by measuring compression of said surge component rubber spring;
an electric over hydraulic brake actuator comprising an electric motor electrically coupled to said controller and rotatably coupled to a hydraulic pump that is fluidly coupled to disc brakes;
wherein as the tow vehicle decelerates the mass of the trailer forces the sliding coupler to compress wherein said controller directs said electric motor to build pressure in the hydraulically operated disc brakes with said controller determining the speed of deceleration for varying a signal to said electric motor to adjust the hydraulic pressure to the brakes.
