ABS questions
 

In the snow today I was trying to slow down and my brake pedal started pushing back and making a buzzing type sound. Its seems like my brakes werent even working because i was skidding all over. I checked out all my brakes and i noticed on my rear right rotor was not shiny like the others. What could this be? I heard its normal with ABS to do that in the snow. It stopped perfect the same morning with no snow.

bump is the abs supposed to pulse like that through the pedal?

i was looking through my volvo 760 owners manual a few weeks back and it said that the abs brakes might pulse...

so im assuming its normal

ABS does not work on ice ...........................
