This cable attaches the Pronto4 brake actuator to the vehicle brake. It has a standard reference number of CA307-80.0-89.5, with the middle number (80.0) representing the housing length (distance from brake pedal mount to bracket), and the last number in the segment (89.5) representing the end to end length from the firewall to the brake actuator arm. The reference numbers are measured in inches, and different lengths of housing and cable can be ordered.
