Brake rotors and brake pads slow or stop your car through the use of friction.  But, did you know that there are two different friction mechanisms at which brakes operate?  If not, no need to worry.  This article will tell you what these two friction mechanisms are and why it will prove useful for you to know.  

 

So, what are the two friction mechansims you say?  The answer is abrasive and adherent friction.  Abrasive friction and adherent friction are the two ways your brakes absorb and handle heat when stopping. While all brakes display a bit of both mechanisms, certain vehicles might utilize one over the other.

 

Abrasive friction is the mechanism by which the energy of motion is transferred to thermal energy
