ok today i was driving home and my brakes decided to lose pressure. It used to be that about 1/4 of the way down you would get pressure now i have to slam it to the floor to get any kind of pressure and it wont lock the tires. While i was sitting there in traffic today i was pumping the brakes and they would get pressure but as soon as i took off again nothing...

Car - 1995 240sx SE w/ completely stock braking system

I know there isnt any air in the lines because they had all been recently bled and were fine until today... MC maybe?

all input is appreciated

thanks in advance

my vote is for either BMC or perhaps a fluid leak.

i checked the level of the fluid and it's the same as it was before, i'm thinking it's the BMC....

yep....sounds like it to me too.

Master cylinder could be leaking internally, bleeder screw left open, Damaged or worn caliper piston seals, water-contaminated brake fluid...It could be many things but most likely the MC if everything else checks out fine.

Thanks for the help fellas, i was thinking it was the MC and we'll find out if we're right later on in the week when it comes in.
