Eco Brake-By-Wire Logo Eco Brake-By-Wire an electromechanical brake technology will increase vehicle economy, while helping electric and autonomous cars maintain its competitive edge in automotive design. Lighter weight of vehicle contributes to less energy consumption and minimizes tires wear.
Environmental benefits, an electrorheological fluid brake system saves energy, reduces air pollution and eliminate dust pollution from the brakes. Implementation of electrorheological smart fluids for the automotive industry will change the way we develop and build cars.
Electric Car Average passenger electric car weight is approximately 3,622 lbs - 1,643 kg
• Compact cars  2,979 lbs   1,354 kg
• Midsize cars    3,497 lbs   1,590 kg
• Large cars      4,366 lbs    1,985 kg
Average passenger car disc brake system, weighs roughly 176 lbs / 80 kg (discs, calipers, brake pads, power booster, hydraulic master cylinder, ABS control unit and metal tubes).

Proposed Eco Brake-By-Wire system total weight is about 66 lbs / 30 kg the 110 lbs / 50 kg less of average hydraulic brakes system. Reducing an automobile’s weight by a 110 lbs / 50 kg increases vehicle economy by up to 3%. Those 3% represents significant reduction of energy consumption.
The electrorheological fluid brake system has high-speed of response, reducing braking distance that is extremely important in emergency situation.
There are an estimated 260 million registered passenger vehicles in the United States and over 33 million in Canada, year 2016.

Eco Brake-By-Wire pros and cons, versus hydraulic brakes:
• Compact design
• Good controllability of brake torque
• Light weight, weighs approximately 4.6 kg each x 4
• The weight of ECO brakes contribute to less electric energy usage
• Constant Anti-Skid monitoring
• High-Speed of response, reduced braking distance
• Long lifespan, no friction linings and no periodic parts replacement
• Hydraulic system is not required (no: master cylinder, power booster, pipe lines and calipers)
• Low or no maintenance
• Environmentally friendly sealed unit, no harmful brake dust pollution

• Require of an alternating electric current to generate braking torque
• Temperature dependency, when temperature increased viscosity decreased
• Lifespan of Electrorheological fluid, unknown
• The fluid cannot be compared on the basis of a single parameter
• Require modification of the current suspension design
