## Abstract

A complementary braking system for removing liquids and solid debris from a motor vehicle's pathway and applying frictional contact in front of two or more of the motor vehicle's tires provide slowing and prevent further movement of the vehicle. The complementary braking system includes a resilient blade disposed forwardly of the motor vehicle's tires and above a road surface. The resilient blade includes an upwardly curved leading edge followed by a generally horizontal flat portion. The system also includes a pair of releasable latches that maintain the resilient blade in an elevated position until released to fall into contact with a road surface The system also includes a pair of electric motors for returning the resilient blade to an elevated latched position above the surface of the road in response to released pressure on the brake pedal.

## Claims

### Claim 1

A complementary braking system for removing liquids and solid debris from a motor vehicle's pathway and applying frictional contact in front of two or more of a motor vehicle's tires to provide slowing and prevent further movement of the vehicle, said complementary braking system consisting of:
a resilient blade disposed forwardly of the motor vehicle's tires, fixed to a motor vehicle's frame above a road surface and said resilient blade including an upwardly curved leading edge followed by a generally horizontal flat portion and wherein said resilient blade is made of steel and has a layer of a hard rubber compound on a lower surface of the leading edge and generally flat horizontal portion;
a pair of releasable latches maintaining said resilient blade in a raised position out of contact with the road surface until released by pressure on a vehicle's brake pedal;
a pendulum including a metal ball for releasing said latches in response to a forward movement of said metal ball in response to initial deceleration to allow said resilient blade to contact the road surface;
a pair of coiled steel high impact springs and a pair of coiled steel lower impact springs for cushioning the impact of the resilient blade contacting the road surface and the blade contacting bumps in the road; and
a pair of electric motors and hydraulic pumps for returning said resilient blade to an elevated latched position above the surface of the road.

### Claim 2 (depends on 1)

The complementary braking system for removing liquids and solid debris from a motor vehicle's pathway and applying frictional contact in front of two or more of the motor vehicle's tires to provide slowing and prevent further movement of the vehicle according to claim 1, in which said pair of electric motors are operatively connected to a pair of rack and pinion assemblies and a gear train between said electric motor and said rack and pinion assembly.

### Claim 3 (depends on 1)

The complementary braking system for removing liquids and solid debris from a motor vehicle's pathway and applying frictional contact in front of two or more of the motor vehicle's tires to provide slowing and prevent further movement of the vehicle according to claim 1, which includes a pair of low impact coil springs made of steel that complement said high impact coil springs.
