It sounds like you got air in your lines. You didn't get into any process where you had a little fluid ooze out? - as this would allow air into your lines.

[Mr. Luos]

Or it is really low on fluid.

Fluid could have gotten out of the cylinder when the calipers got compressed.
Just another possible thing to check.

Did you burnish the pads to the rotors?
Was there any rust preventor on the rotors...did you clean the rotors before installation?
What did the surface finish of the rotors look like?
Did you torque the lug nuts or just tighten them down?

Sounds like diminished braking ability...maybe poor quality componants
