2004 Ford Focus Clutch Master Cylinder Parts Q&A

• Q: How to service and repair the clutch master cylinder on MT285/MTX75 transaxles on 2004 Ford Focus?

  A: The first step for clutch master cylinder services on MT285/MTX75 transaxles is to disconnect the battery ground cable. It is important to exercise caution regarding brake fluid damages because paint so use immediate cold water cleaning to avoid harm. A syringe tool should be used to drain brake fluid from the reservoir until the MIN level is reached before reattaching the cap. The service begins by removing the air cleaner followed by detaching the Central Junction Box (CJB) after unbolted retention and clip release. The clutch master and slave cylinder supply lines need cap installation for preserving fluid before using a thin bladed screwdriver to detach them by removing their clips. The user must start by removing screws from the instrument panel lower panel before releasing the fastener to detach the panel completely along with disconnecting the Data Link Connector (DLC) and hood release cable. Start by removing the clutch slave cylinder supply line from the front bulkhead with a clip removal. Then procede to depress the locking tang of the brake pedal actuating rod retaining pin for removal. Removal of the pedal assembly begins with disconnecting electrical connectors from the speed control deactivation (green) and stop lamp (grey), clutch position (red) and starter safety (black) switches before removing the switches by color for later reference. To access the clutch master cylinder retaining bolts, it is necessary to remove the complete pedal assembly completely. Position the pedal assembly in a vise then remove retaining bolts to separate the clutch master cylinder from the pedal assembly by sliding the actuating rod off the pedal arm. The installation process starts by connecting the actuating rod to the pedal arm together with the clutch master cylinder to the pedal assembly before placing the assembly inside the vehicle. First secure the brake pedal actuating rod retaining pin by locking its tab into view then put the pin in place. Fasten the pedal assembly with retaining nuts before connecting the front bulkhead through the clutch slave cylinder supply line with its clip. Extend the plungers of the black starter safety switch and green speed control deactivation switch and grey stop lamp switch to their full length before measuring: place 24 mm on the speed control deactivation switch while the starter safety switch reaches 26 mm and the stop lamp switch reaches 21 mm. Install the switches by turning the stop lamp switch counterclockwise and the remaining ones clockwise to prevent possible binding. The speed control deactivation switch and stop lamp switch will automatically regulate during the installation procedure while basic ratcheting sounds are expected. After placing the switches back onto the pedal assembly users need to connect the electrical connectors followed by adjusting the starter safety switch through clutch pedal operation. When necessary use new O-ring seals and then connect the fluid supply lines from the clutch master cylinder to the slave cylinder while securing them with clips. Secure the hood release cable and the Data Link Connector (DLC) to the instrument panel lower panel while attaching panel trim by fastening its component and securing screws. Finish the installation by attaching the Central Junction Box to its bracket through a retaining bolt and retaining clip. After completing this step you can proceed to install the air clean and add Super DOT 3 brake fluid to the reservoir before bleeding the hydraulic clutch system, concluding with battery ground cable reconnection.
