Toyota Tsusho Cworks BRAKE MASTER CYLINDER 47201-0D220

The automotive brake master cylinder is the core component of a vehicle's braking system. Its primary function is to convert the mechanical force applied by the driver to the brake pedal into hydraulic pressure. This pressure is transmitted through brake fluid to the brake calipers (or wheel cylinders) at each wheel, pushing the brake pads to make contact with the brake rotors (or drums). This friction generates the force needed to slow down or stop the vehicle.
