Janel Hydro Company, in conjunction with Automation & Control Services (ACSS) of Schererville, Indiana, has completed further preliminary tests of the Hyperbrake system this week in Griffith, Indiana. The preliminary test results indicate neither heat nor cold stressing will negatively affect the Hyperbrake system operation.
The Hyperbrake is a novel fully hydraulic braking system that increases the pressure of hydraulic fluid by means of a mechanical advantage inherent in a single or dual piston(s) with a large input ratio versus a small output ratio. The device multiplies output pressure through coupled pistons, an interconnecting cylinder and a spring loaded feedback valve.
In physics terms, it is analogous to a lever, the company says. It employs pure hydraulic forces, requiring no electric or vacuum assisted power. The Hyperbrake can be utilized in any hydraulic system, according to Janel Hydro, and is being used on several experimental automobiles.
The preliminary thermal stress tests of the Hyperbrake were very successful. Heating the unit to 202 degrees Fahrenheit and cooling the unit to -46 degrees Fahrenheit had no substantial adverse issues with the operation of the unit. The test ran just as we had expected.

Our initial milestones have been completed with our successful testing of the Hyperbrake. We will now move forward identifying potential development partners to work with us in bringing this product to the automotive, heavy equipment, aviation and other markets with hydraulic applications.

|The Hyperbrake multiplies pressure by taking in more fluid from the master cylinder than it delivers to the brake system. To realize the pressure increment, an auxiliary valving system is required, with a central check valve plays the crucial role. The current design uses two pistons to compact the design, so that the pistons have longer stroke without making the Hyperbrake oversized. Click to enlarge.|
The Hyperbrake is installed between the master cylinder and the wheel cylinders of the automotive braking system. Receiving brake fluid under pressure from the master cylinder, the Hyperbrake delivers brake fluid to the wheel cylinders at an increasingly higher pressure. The harder the driver presses his or her foot on the brake pedal, the more the output pressure of the master cylinder is multiplied. In most stock braking systems, the vacuum power assist and master cylinder mechanisms on most cars and light trucks performs the same function. Use of the Hyperbrake thus allows the removal of the vacuum booster system which is currently standard on all new automobiles.
Through removal of the booster, weight and fuel savings are created while eliminating the cost of the vacuum booster. Preliminary on-vehicle testing shows stops of up to 166 feet less with the Hyberbrake system than vehicles without the Hyperbrake system installed, thereby increasing vehicular safety. The Hyperbrake has the potential to save precious underhood space, improve fuel economy, and reduce required parts and their associated costs, Janel Hydro says.
Janel Hydro Company was founded in 1991 in Detroit, Michigan by Leo Cooney. The original concept of the Hyperbrake technology was originally developed by Axel Jansson, father-in-law of Cooney, and also a former Chief Brake Engineer for General Motor Corporation.
2005, Chinese entrepreneur Tan Chen purchased the company, and began working with former professional racing driver Paul Goldsmith (Motorsports Hall of Fame 2008) to commercialize the technology.
