Bench Bleeding Clutch Hydraulic System (F250-F550)
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
So as not to trap air in the clutch hydraulic system, fill any disconnected component (such as master cylinder and slave cylinder) with High Performance DOT 3 Motor Vehicle Brake Fluid (C6AZ-19542-AB), before connecting it. DO NOT allow the clutch master cylinder reservoir to run dry.
- Support the clutch hydraulic system components so that the reservoir is above the master cylinder and the slave cylinder is below the master cylinder. See Fig 1 . Fill the clutch master cylinder reservoir to the full line with High Performance DOT 3 Motor Vehicle Brake Fluid (C6AZ-19542-AB).
- Push the push rod slowly into the slave cylinder until it bottoms out the piston. Hold the push rod in this position for 5-10 seconds to allow all trapped air to rise through the system. Look for air bubbles in the fluid in the clutch hydraulic reservoir.
- Very slowly, so that air is not drawn back into the slave cylinder, release the pushrod (the spring in the slave cylinder will force the piston outward).
- Wait 5-10 seconds for the air bubbles to rise. Repeat this process 5-10 times to make sure that all air purged from the system. Verify that the fluid level in the reservoir is correct, and install the cap.
