idle jumps when i brake!

i have a 2004 g35x. i've install a k&n drop in filter. when i brake my i see that my needle bounces up and down from 500rpm to 1000rpm. it only does this when i slow down to brake.

mine does it as well, but I sort of figured maybe it's from the transmission downshifting?

Its brake assist...the car uses the engines rpm's to help so the car down taking some pressure off of the brakes system..my 04 sedan doesn't have it but my 05 V6 altima does...
