FORD LIGHT TRUCK: 1993 AEROSTAR, BRONCO, EXPLORER, F-150-350 SERIES, F-47, RANGER UNRESPONSIVE CLUTCH: AIR ENTRAPPED IN HYDRAULIC SYS

64
Download ISSUE A “soft” unresponsive clutch pedal may be felt or the driver may be unable to release the clutch. This is caused by air entrapped in the clutch hydraulic system. ACTION Use the information in this TSB article in addition to the appropriate bleeding procedure. This article includes detail as well as extra service tips for easier hydraulic clutch bleeding. The clutch hydraulic system for the 1993 model year is new and more difficult to bleed than the previous hydraulic system. Therefore, a different bleeding procedure is required for these vehicles. RANGER, EXPLORER, AEROSTAR The most difficult systems to bleed are on the Ranger, Explorer, Aerostars. NOTE: When installing dry clutch cylinder or tube service parts, do the bench bleed procedure first. BENCH BLEED The compact vehicles are more difficult to bleed because the downward angle of the master cylinder makes it difficult for air to escape up into the reservoir. Therefore, if the master cylinder is removed from the vehicle and bled while held in a vertical orientation (a bench bleed) air can escape much more efficiently.
