What is a brake master cylinder?

The brake master cylinder is a component in your car's braking system that drives the pressure generated by the brake pedal to the braking mechanism

What does a brake master cylinder do?

The brake master cylinder converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force.

What happens if brake master cylinder fails?

The brake master cylinder will be unable to provide proper pressure, and the pedal will feel very different.

What happens if I continue to drive on it?

It will wear out the cylinder and start leaking. The pedal will also feel spongy, and mushy, and may sink far down when pressed. Therefore leaving the vehicle with ineffective braking. If your master cylinder has failed stop your vehicle and have it towed to prevent safety-related issues as well as damaging your vehicle further.
