Please help before I go poor. I had new rotors and pads put on my ride. Car stops on a dime if I come to a hard stop. When I do a really slow stop the I get a lot of grinding and it feels like the ABS is kicking in.

Went to two mechanics and they say the pads and rotors are perfect. Can anyone tell me why I get a grindng and ABS pulsating feel when I do a slow stop?

Any help would be appreciated.
