Could be: low fluid, brake line broken, leaking wheel cylinder, bad caliper, bad master cylinder inspect all those components.
Check the level in the master cylinder - if it's empty, you have a leak - most likely a failed brake line. If it's full, you need a master cylinder.
it has something to do with brake fluid.it could be a few things like a broken line or hose.also a wheel cylinder could be leaking or the master cylinder is bad. if there is a wheel cylinder leaking, a line or hose then it can suck air and cause it.
