Default brake pedal sinking to the floor at stoplights, but my fluid level does not change?

My brake pedal sinks to the floor when I'm at stop lights. I'm not leaking any brake fluid because the level in the MC is always at the top.

Would my MC still be bad? or is it my Brake Booster? or could it just be I need to keep bleeding my MC a lot more?

thanks.

It's called an internal bypass. Fluid is going around your worn out MC piston seals and back into the reservoir. Happens all the time.

your brake master cylinder's internal seals are shot. replace it with a new one, dont bother getting a reman one they are junk.

trust me i know. the same thing happened to me and i went through 3 remans before i got one that worked.

make sure you bench bleed the new mc properly before you hook it up and then bleed the brakes again to make sure that all the air is out of the lines.
