Master cylinder

A master cylinder is a key component of a vehicle's braking system. It converts the force you apply to the brake pedal into hydraulic pressure using brake fluid. When you press the pedal, the master cylinder pushes fluid through brake lines to the brake calipers or drums, causing the brake pads or shoes to press against the wheels and slow or stop the vehicle. It acts as a reservoir and pump, ensuring consistent and reliable pressure to activate the brakes efficiently and safely. Proper functioning of the master cylinder is vital for responsive and effective braking performance.
