Towed vehicle braking system

In a towed vehicle braking system having components substantially within a braking system case and including a fluid compressor, a fluid actuator with a moveable piston, a mechanism for connecting the piston to one of a brake pedal and a hand grip means, circuitry for controlling the fluid actuator and means for sensing decreases in a towing vehicle's velocity connected to operate the circuitry to obtain braking pressures of 20-75 psi in the system's braking system, the improvement comprising:

• free-standing means for positioning the system on a floor of the towed vehicle between a driver's seat and the vehicle brake actuator;
• at least one of
• means for sensing decreases in towing vehicle velocity and
• means for sensing separation of the towing vehicle from the towed vehicle
• connected to at least one of the fluid circuitry and electrical circuitry to cause predetermined braking by the towed vehicle's braking system on a decrease in velocity of the towing vehicle and/or separation of the towing vehicle from the towed vehicle;
• and
• remote towed vehicle braking control transmitter, usable by a towing vehicle driver to transmit coded signal(s) to a towed vehicle receiver braking system, and connected to the at least one of the fluid circuitry and electrical circuitry of the towed braking system to cause braking by the towed vehicle braking system on receipt of appropriate coded signals and located external to the case enclosure, an attached adjustable positioning means comprising at least one of a scissors jack and shims, the system being powered by at least one of a self contained battery and electrical power from the towing vehicle and the towing vehicle velocity decrease sensor is one of a pendulum and a microswitch and a pendulum and a proximity sensor.
