brake install probs
So i just put on my iRotors and hawk hps pads today. Something is amiss. The pedal feels spongy and i don't get noticable stopping power till the pedal is near the floor? I didn't disconnect the brake line from the caliper so i didn't feel the need to bleed the brakes. any ideas?

looked a little low but the fact remains is that the brakes performed normal with 41k on them and now that I have new performance parts on the car and somethings isn't working the same.
EDIT: Let me refraise. When the brakes where stock the fluid was like .5 inchs low. When i pushed the brake pistons in to fit them over the new pads the fluid went past the full line (for obvious reasons) but now after i pumped the brakes and drove it around the block a few times the fluid level still hasn't come back down to where it was prior me pushing the pistons in. That mean I have to bleed the lines?

When you pushed the pistons on the calipers in to accomadate the new pads, did you open the bleeder or just push them in pushing the fluid into the master cylinder reservoir. On cars with ABS you should open the bleeder to push the caliper pistons in. With ABS you have one way solenoids that are used for the braking system and ABS something could have happened to them solenoids.

If you open the bleeder in the caliper to push in the piston, you are intruducing air into the system (and probably losing fluid). At which point you must bleed the system and add fluid.
I have never heard of needing to open the bleeder to push in the caliper piston(s). I just remove the cap on the master cylinder prior to replacing pads and put it back when I'm done.
