check under your master cylinder,is there another clyinder below with one line in and one line out,if you do I found this is for the Abs to the rear,I had to replace this it was full of air,and did exactly what yours is now

Yes master cylinder and maybe ABS sending unit. Also is there a sound of an air leak it may also be your brake booster

Either a bad caliper or wheel cylinder. In the majority of the cases, the cylinder is to blame. But if you want to be safe, replace both to cover your bases.

DEPENDS WHAT PROCEDURE YOU USE TO REPLACE THEM.IF YOU PUSHED THE CALIPER PISTONS IN WITHOUT OPENING THE BLEEDER AND USING A **** CLOSED THE BRAKE HOSES YOU MANAGED TO SENT BACKWARDS THE FLUID INTO THE MASTER CYLINDER WHERE IS THE POSSIBILITY TO CAUSE THE SEALS ROLLING IN AND ARE NOT HOLDING PRESSURE. THE OTHER REASON IS EITHER YOU NEED TIME UNTIL THE BRAKES BED ON THE DISCS SURFACES.
