Just added to our existing brake line - A brake capable of being installed in semi trucks used for truck driving schools.  Same brake concept with extended cable housing and coupler.  See attached photo and video
Provides positive braking and ease of operation by the driving instructor. The use of aircraft grade cable and fittings insures safety. The Dual Brake Set installs completely within the passenger compartment, even in vehicles with limited space under the dash. The actuation cable can be easily adjusted to length during installation. NOTE: The cable housing must be cut to exact length from Big Base to Mini Base. The more direct route the better the cable will operate. 
The instructor's brake pedal assembly is made from custom aluminum castings. The brake pad swivels for comfort. A small riser plate can be used to compensate for the vehicle's floor slope. This "Riser Plate" #111 is (sold separately) and is usually not necessary. Also available is the "Bison Adjustable Brake Stabilizer" #175 (sold separately) which allows the brake to be installed on the passenger side with out drilling into the floor board.
