How Brakes Work

All drivers know that putting your foot on the brake slows the vehicle down, however, many do not know exactly how the brake system works.

The force applied to the pedal is multiplied through leverage which then, in turn, initiates a hydraulic system. Hydraulic systems run on incompressible fluids, in this instance brake fluid. The leverages force at one end, pushes a piston into a brake cable, which pushes the fluid through the brake cable and pushes a piston out of the other end, apply the friction to a wheel. This is the braking system. This friction is relayed through the tyres to the ground and vehicle comes to a stop.

Over time, brakes can fail for several reasons; a leak of fluid in the hydraulics can cause weak or failed brakes. Additionally, over time, the frequency and intensity of the application on the braking system can wear the brakes and component parts: these need to be monitored, serviced and as they deteriorate replaced. Good driving ethics and cautious driving can prolong brake life.
