Dragzine: Proper Hydraulic Pressure Is The Root To A Good Brake System

Written by: Todd Silvey

In some theories, a brake “system” is comparable to a racing engine. A racer concentrates on an accumulation of components to build a high-horsepower engine, but the wrong choice for a cam, timing, or many other elements can result in much less available power.

The same goes for the brakes to stop your hot rod. Components from here, there and anywhere may provide you with brakes, but is it a proper system that will adequately stop all that rolling inertia once it hits the dragstrip finish line?

The most prominent concept when working with a race car brake system is the measurement and monitoring of your hydraulic pressures inside your brake lines. Your brake lines are nothing magic; they transfer pressurized brake fluid from the master cylinder to your brake calipers. Short of a pinched line or leakage, their function is simplistic.

The determining factor for proper stopping power is what happens before and after the said brake line. The starting point of the brake pedal and master cylinder is one half of the combination; the calipers plus the related pads and rotors make up the critical end-game of your system.

Three physical laws govern the relationship between master cylinder and calipers; those rules include brake volume, brake pressure, and brake balance. Though our topic is brake pressure, these three points must work in orchestration, just like the racing engine mentioned above.
