  Q: How to remove and replace the clutch master cylinder on Ford Focus?

  A:

  A proper replacement of the clutch master cylinder needs you to start by disconnecting the battery ground wire. The process of brake fluid extraction should stop once the MIN mark shows on the reservoir while maintaining the reservoir cap clean from contamination. The central junction box (CJB) can be separated from its mounting bracket when you remove the plate retaining bolt and unlock the mounting clip. First stop the hydraulic supply at the upper and lower lines before removing clutch hydraulic connections to prevent fluid leakage. Perform instrument panel lower panel removal by first unscrewing the fastener followed by releasing it while also detaching the hood release cable along with the data link connector. Use a leading wrench to detach the upper hydraulic line from the front bulkhead while pressing the locking tang for brake pedal actuating rod retaining pin removal. Next disconnect the electric cables from the pedal assembly that connect to the starter safety switch and clutch position switch and speed control deactivation switch and brake lamp switch. The complete clutch pedal assembly and clutch master cylinder requires full removal to reach the clutch master cylinder bolts because users must first remove clutch pedal assembly nuts then detach the assembly itself. It is necessary to mount the clutch assembly in a vise and to remove clutch master cylinder bolts before separating the clutch pedal from the master cylinder. The new clutch master cylinder installation requires positioning it onto the clutch pedal assembly followed by fastening the actuating rod while torquing the bolts to 9 Nm (80 inch lbs.). Position the clutch pedal assembly within the vehicle while verifying the brake pedal actuating rod retaining pin stays locked in position then add assembly nuts and tighten them to 23 Nm (17 ft. lbs.). Secure the front bulkhead lower hydraulic line by attaching it and installing the clip. Set the buttons of the braking lamp switch at 21 mm length with clockwise rotation and the speed control deactivation switch and starter safety switch set to 24 mm and 26 mm respectively following clockwise direction. Mount the switches properly while ensuring a counterclockwise orientation of the brake lamp switch to prevent binding. Begin by connecting electrical wires to the switches followed by adjusting the starter safety switch through clutch pedal activation then install fresh seals into place. Build up the threads by connecting supply lines between clutch master cylinder and slave cylinder before applying the clips. You need to reinstall the hood release cable followed by the data link connector while placing and screwing in the instrument panel lower panel trim then remount the CJB onto its bracket. Follow the procedure to fill the brake fluid reservoir to its MAX mark while using the fluid recommendation then perform a hydraulic clutch system bleed before reattaching the battery ground cable.
