I was sitting at a stop light last night and while sitting there my brake pedal pops and goes to the floor. My brakes work probably at about 15% its only enough to slow me down if i'm going under 25mph. Not sure what it is i assume its a brake line because i checked to see if there was brake fluid and theres barely any at all in it now.

second opinions?

 

have you checked your brake lines?

 

i havent had a chance to check them because i have no garage and its been raining but thats the only thing i could think of it being seeing as i could hear and feel the pop and my girl said she could feel it too

 

Its definately a rusted brake line or rotted rubber line.

 

Possibke master cylinder rings failed.. See if brake fuid is leaking by where the pedal is

 

is the paint from your vacum booster(that thing were your master cylinder is attcahed to) peeling off? if it is then you have a leak, which means your the rings on your primary piston have failed.
