Heavy-Duty Master Cylinders for Your Semi-Truck

The master cylinder is a component in your semi-truck's braking system that transfers the pressure generated by the brake pedal to the braking mechanism on the tires. When you press down on the brake pedal, the force moves a piston to the brake cylinder, which converts into hydraulic pressure. The same pressure moves hydraulic fluid to the brake lines, applying pressure to a secondary cylinder at each wheel.
