It does work, the FIA S2 group A rally car I service has this feature (per 
MTM and AS) on both front and rear brakes.  Squirts on the rotor vents, and 
uses 2 pumps with a driver adj duty cycle (independent front/rear actuation 
control, from 1 min to continuous, or per brake application).  We rarely need 
to actually run it, not many really hot days and/or long tarmac stages in the 
US Rallys (audi SQ brakes).
