2003 Ford Focus Clutch Master Cylinder Parts Q&A

• Q: How to service and repair the clutch master cylinder on MT285/MTX75 transaxles on 2003 Ford Focus?

  A: The first step to work on the MT285/MTX75 transaxles clutch master cylinder entails removing the battery ground cable. Take safety measures to stop brake fluid from touching car paint since immediate cold water washing can remove any spillages. A syringe should be used to drain brake fluid out of the reservoir until it gets to the MIN line which must be followed by replacing the cap. Start by dismounting the air cleaner before removing the Central Junction Box (CJB) retaining bolt and unclipping it. Before undoing the fluid supply lines protect them with clips while also using a thin bladed screwdriver to disconnect the lines from the clutch master cylinder and slave cylinder. Remove the clips after disconnection. Use a screwdriver to remove screws from the instrument panel lower panel while also releasing the fastener followed by removing the panel with separate detachment of Data Link Connector (DLC) and hood release cable. The clutch slave cylinder supply line requires disconnecting from the front bulkhead while also removing the retention clip. Pull back the retaining pin locking tang to expose the actuating rod but first disconnect all electrical connectors for the starter safety switch plus clutch position switch, speed control deactivation switch and stop lamp switch from the pedal assembly then remove the switches. To gain access to the clutch master cylinder bolts the pedal assembly needs to be fully detached from the vehicle; after which users should mount the assembly in a vise and remove retaining bolts before disconnecting the pedal master cylinder from the pedal assembly as the actuating rod is pulled off the pedal arm. The installation process requires users to attach the actuating rod to the pedal arm and the clutch master cylinder to the pedal assembly before they can position the pedal assembly inside the vehicle. Lock the brake pedal actuating rod retaining pin into position where its locking tab becomes visible before installing the pin. The first task involves installing the pedal assembly retaining nuts followed by attaching the clutch slave cylinder supply line to the front bulkhead while installing the clip. Measure the extremities of the extended plungers starting with green speed control deactivation switch at 24mm followed by grey stop lamp switch at 21mm and concluding with black starter safety switch being 26mm in length. The installation process requires turn of the stop lamp switch in counterclockwise direction while moving the other switches clockwise to reduce potential binding issues. The order to install switches begins with the green speed control deactivation switch followed by a grey stop lamp switch then red clutch position switch and ends with the black starter safety switch. Connect electrical connectors to each switch while adjusting the starter safety switch through complete pressing of the clutch pedal. The installation process requires new O-ring seals while you need to connect the clutch master cylinder and slave cylinder fluid supply lines after you place their clips. Fasten the instrument panel lower panel by attaching screws and fastening the hood release cable and the Data Link Connector (DLC) and ultimately install the panel trim. Reinstall and connect the Central Junction Box by attaching the clip followed by installing the retaining bolt and putting back the air cleaner. Finish the fluid operation by bleaching the hydraulic clutch system and topping up the brake fluid reservoir and brake fluid reservoir with Super DOT 3 brake fluid. After that reconnect the battery ground cable.
