i took off my front calipers, pushed the pistons back and replaced my pads. placed them back on the rotors, hooked the lines back up and bled them and still no brake pressure when i squeezed the brake lever. any ideas?

 

How many times did you squeeze the lever? Once you push the pistons back in you need to pump a few times to build the pressure.

If you did that, then you still have air in the lines. Re-bleed.

 

yup, yup as kevin mentioned. Also wipe down the discs for any oil residue removal.

 

when i squeeze and hold in my front brake lever, do i let the air out on both calipers or one caliper at a time?

 

Try like KEV said. Put your bike in a stand spin the whell and pump the brake several times. Might be as simple as that. I did mine about 2 weeks ago and thats what solved my issue.

 

my brakes r fine now. just had alot of air in the lines. thank you all, big help to me and my zx7. i'll b posting pics up here this week
