Brake master cylinder

Chapter: C12

In Simple Terms

This rule covers the brake master cylinder - the component that converts a driver's foot pressure on the brake pedal into hydraulic force to stop the car. It includes the push-rods that transfer pedal movement, the brake balance system that distributes stopping power, and any electronic components controlling these systems. All these parts must be securely attached to the survival cell (the car's main safety structure).
