This is a very dangerous situation as the braking system is one of the most important safety features of a vehicle. Have a brake inspection carried out by a qualified technician such as the ones here at YourMechanic to look for any leaks in the braking system. One or multiple things can cause this such as, a failed caliper, wheel cylinder, any section of brake line could have rusted through or blown out from being weakened from rust. Also, if a braking system has been worked on recently and wasn't bled properly a large amount of air could be in the system causing the same type of issue.
