Master Cylinder

A master cylinder is a critical component in a vehicle's hydraulic brake system. It converts the force applied by the driver's foot on the brake pedal into hydraulic pressure, which is then transmitted through brake lines to actuate the brake calipers or wheel cylinders. The master cylinder contains a piston that moves within a sealed bore, drawing brake fluid from a reservoir and distributing it to the brake system when the pedal is pressed. Proper function of the master cylinder is essential for maintaining safe and effective braking performance in automobiles, motorcycles, and other vehicles equipped with hydraulic brakes.
