hey guys, what's up- I have a 2k2 maxima, and about 13k miles. and I have just recently been experiencing problems with my brakes. When I apply my brakes, my RPM's fluctuate (go up and down). Not only that, but i can also feel some sort of 'grinding' from the brakes. I JUST WANT MY CAR TO FEEL LIKE NORMAL!!!

Can someone pls. help me out..

Thanks in advance..

later..
