my breaks

[Tree]

so when i pull up to a red light or just stop, my break pedle will be furm at frist the about 20 to 15 seconds later it will start to get really soft, or even to a point here it feels like i'm not pushing it in... my car will start to roll alittle. then if i let it out then press it back in it will so the same thing again... what can it be? rep for anyone that can help

io cant rep you

like I said, check the master cylinder as well, one of the internal seals could have given out or have a pinhole in it.

Take the lines off the ,master cylinder, block them off with a bolt but dont tighten it to much or it can damage the master cylinder, an mash down your peddle, if it is hard an dont go down you have another problem , but if it leaks down soft you need a new master cylinder, to take off your lines, use a 10mm Flare wrench only

sounds like a master cyl. to me go to autozone and pick one up shouldnt take you more than 30 min me and a buddy just did it on my hatch last weekend

if you drive on it too long you can cause the booster to leak as well, so fix it sooner rather than later.
