Remove the parking brake assembly from the floor. Follow this procedure to reset the cable and ratchet assembly.
With the front parking brake cable and conduit on the floor, step on the front parking brake cable and conduit or clamp the end of the front parking brake cable and conduit in a vise.
Pull on the assembly, holding the mounting bracket tightly against the body of the control, until cable tension rotates the cable track assembly so the lock pin can be fully seated through the plate.
Insert the lock pin so the assembly is in the "cable released" position.
Install the parking brake control. Refer to the Removal and Installation, Control, Aerostar or Ranger procedure in this section.
A punch will work for a locking pin.
Are the cables on the rear end now the ones that came with the Aerostar you have?
And yes it does make sense. If the cables on the rear end are the original ones from the Aerostar, they should reach, you just have to stretch the cable at both ends. The rear end and the parking brake handle. If they are not the original ones, you need to put the original ones back on.
