The Wilwood Mechanical Spot Caliper offers good potential for an emergency brake add on.  Of course, steel mounting brackets will need to be fabricated and the OEM cable configured to work with the caliper.   Cost is about $60 each (retail).  Left and right side calipers are available.  Cable stops from the Mustang Parking Brake kit make the job easier.  Contact Wilwood at
