Bench Bleed Procedure
BENCH BLEED PROCEDURE1. Remove master cylinder, line and reservoir from vehicle and assemble with replacement parts required based on initial concern.
2. Hold the master cylinder vertically with the reservoir feed hose in the highest position on the body, Figure 5.
3. Fill the reservoir and extend above the master cylinder and assure the quick-connect on the clutch line is below the master cylinder. (Lightly clamp reservoir in a vise).
4. Using a small screwdriver, depress the internal mechanism of the male quick-connect coupling to open the valve, Figure 5.
5. Stroke and hold master cylinder pushrod.
6. Close quick-connect valve.
7. Release master cylinder pushrod.
8. Fill reservoir.
9. Repeat Steps 4 through 8 four more times.
10. With the master cylinder still being held with the outlet tube and reservoir feed tube ends high, quick-connect closed and the reservoir full, proceed as follows:
a. Push the pushrod into the body several times quickly to expel any remaining air.
b. If it is a remote reservoir, pinch the supply hose with your fingers two or three times to help move air into reservoir.
11. When the movement of the pushrod is .1601, (4 mm) or less when stroked in Step 10, reinstall the master cylinder into the vehicle and couple it to the slave cylinder per 1993 Ranger Service Manual Procedure, Page 08-02-03.
