problems with my breaks

[TransAmFanatic]

ok i changed my front break pads yesterday, and i compressed the pistons so the new pads can fit. after i did all that, i bled the lines and put everything back together. well now i only get pressure when the car is off. i turn the car on and get no pressure whatsoever. this happened before, and i bled the lines with the car off, and it worked. well i did that and still no pressure. any info would be greatly appreciated.

Sounds like you still have air in the lines

or your master is on its way out

try more bleeding

if you didn't open up the lines there was no need to bleed them in the first place. You didn't run the resevoir dry when you were bleeding them did you? Might just need to keep bleeding them...sometimes it'll take a few times to get the air out. How are you bleeding them? Make sure you're not sucking air back in there. I use a piece of clear tubing over the bleeder and put the open end down into a bottle of fluid....keeps you from sucking air back in and the clear tube lets you see when the bubbles stop.

ill keep bleeding them, i did not pop the lines open when i replaced the pads, the only thing i did was compress the pistons back so i can put the pads on.

How many times did you pump the brake pedal once you were done installing the pads? Or at least DID you pump the brake pedal once you were done installing the pads? When I replaced my pads and cut my front rotors I pumped the pedal to get pressure back to the system.
