there are numerous types of parking brake aplications for rear disc brake
vehicles.  some use a drive shaft band  or disc brake that is purely
mechanical in it's aplication and release.  some have the  most common set
up of mini drum brake type shoes inside the "hat" of the disc brake rotor .
and there are independant inboard disc brake parking brakes and there are
calipers with a lever on the caliper that actually applies and releases the
caliper piston as the park brake.   somewhat over simplified in my
explanation but the point being that numerous manufacturers have attacked
the problem in a myriad of ways.  the end result being a suprise with evry
pulled rear wheel on a 4 wheel disc brake car!

what's next?  an electronically applied parking brake?
