The simplest way to describe a split braking system is to visualise that the pressure to the brakes are applied to the wheels on separate lines carrying a special hydraulic fluid. This is done for several reasons, safety among them. There are two basic types of split braking systems. One is a front and rear split system. The second is called a diagonal split braking system. There are different reasons for both, though they share the common goal of straight-line braking.

## A Primer

Since braking systems work based on hydraulic fluid that runs through lines that apply pressure to braking cylinders in the wheels, a brake line failure may prove catastrophic. If the line leaks or breaks for any reason, pressure is lost. Without pressure when the brake pedal is applied, the braking cylinders in the wheels couldn't apply the force needed to stop the wheels from spinning and, in turn, not stop the vehicle. This applies to both systems.

## Double Back-Up

Sometimes, split braking systems use two master cylinders to control each conduit (brake line). This is akin to a double safety backup. Since master cylinders exponentially increase the force of the hydraulic fluid to the brakes, should one fail, the vehicle still has stopping capability, albeit the stopping distance is greater and less even (more difficult to control). On the other hand, with two master cylinders, the system has one more additional part that could fail, but engineers consider that the safety features outweigh the potential for failure if properly maintained.

## Diagonal Split

The diagonal split concept comes from the fact that the left rear and right front brakes are on one hydraulic line while the right front and left rear brakes are on another. The diagonal split system, because it maintains braking ability for both a front and rear tire, is easier for the driver to control the vehicle in emergency brake failure. In a nondiagonal system, all the braking power would transfer to either just the front or back tires, increasing the likelihood of skidding and possibly losing control.
