Four Possible reasons... Low brake fluid - check the brake fluid level in the master cylinder Emergency brake is on - check emergency brake Low brake fluid pressure - such as a broken brake line or a bad wheel cylinder. Check the master cylinder to see if it is empty. If you add fluid and pump the pedal you will probably see brake fluid on the ground or on the inside of the tires. Possibly a bad master cylinder. - The fluid will stay full but you will have no or little brake pressure. Could be air in the system as well. BE CAREFUL If you happen to add power steering fluid or transmission fluid to the master cylinder instead of brake fluid you will destroy the system. Make sure you use ONLY brake fluid and clean the master cylinder cap off with a clean rag first so no dirt gets into the braking system.
You ONLY lose brake pressure if you have a leak somewhere ! - This can be in any wheel cylinder , the master cylinder, or a fractured brake line. Till you find the leak, keep your master cylinder topped up daily.If the brake fluid reservoir remains full and the brake pedal sinks to the floor as you are waiting at a stop light, the master cylinder is at fault.
There is a leak in the brake hydraulic system and the brake fluid has leaked out of the master cylinder enough to induce air into the system and result in no pressure in the braking system. This is too dangerous of a situation to drive on. A vehicle in this condition needs to be towed somewhere to be repaired. Likely a brake line or hose has ruptured and has leaked out a majority of the fluid. Also it is common for a caliper or wheel cylinder to leak, especially if the brakes have been grinding for a while and now suddenly there is no pedal pressure. All parts of the hydraulic system need to be inspected for leaks and repaired properly.
There is a smaller master cylinder next to the brake master cylinder. The clutch uses brake fluid also. If you mean where does it go if it is low, the slave cylinder on the transmission is probably leaking.
If your talking about the brake bleeder, it is on the caliper/brake cylinder at the wheel.
A piston on each end of the wheel cylinder pushes outward when the brakes are applied. This pushes the brake shoes against the brake drum and stops the vehicle. The pistons are forced out by the pressure of the brake fluid inside the wheel cylinder when you apply the brakes.

I advise you to perform a careful examination of your car's brake system.
According to the Owner Guide , the clutch master cylinder and the brake master cylinder are part of the same system . The clutch and the brake system can be filled at the brake master cylinder with DOT 3 brake fluid
It's really simple it transmits the power from your foot on the pedal to the brake system from mechanical to hydraulic which eases the braking which is afterwards reconverted to mechanical friction by the caliper.
To notify the driver that there is a problem with the brake system.
The clutch master cylinder and the brake master cylinder are part of the same system . Both can be filled at the brake master cylinder using brake fluid
It is the pump cylinder in a braking system, operated by the brake pedal and its assisting servo.
If it is a drum brake system, then you will have to remove the wheel ,drum, brake shoes, and hydraulic brake line , then remove and replace the cylinder with a new one re-assemble and bleed the hydraulic brake system
