The Brake Guard HD 500 ™ Series is a patented system designed to improve the performance of vehicular hydraulic braking systems. Purely mechanical with no electronics, it compensates for transient pressure spikes associated with minor irregularities in the braking surfaces.

The two Patented hydraulic accumulators of the HD 500 ™ Series automatically dampen these transient pressure spikes, thereby increasing and equalizing energy absorption rates at each braking surface and reducing differentials of braking action between wheels.

The HD 500 ™ is specifically designed for lighter  vehicles including passenger sedans,  mini-vans, small pick-ups and taxis.
