No Release / Air Trapped in Hydraulic Release System

Applications:
1983-94 Ford Ranger - 2.8L and 3.0L
1991-94 Ford Explorer - 4.0L
1991-94 Ford Bronco II - 2.9L
1993-97 Ford Explorer - F150-350 - Ranger
1986-95 Ford Aerostar




These applications require special procedures to bleed the hydraulic system properly. The mounting position of the master cylinder on the firewall traps air in the rear portion of the cylinder. Before bleeding the system, remove the master cylinder from the firewall and position it so the reservoir end is higher than the push rod end. This will enable air to escape from the rear position of the cylinders. Use only approved hydraulic fluid recommended by the manufacturer. We highly recommend the use of a Phoenix Systems V12-205 V-12 Injector Bleeding System with Smart-Pak. For additional information, refer to Ford bulletin #93-12-19.
