  Q: How to overhaul the Clutch Master Cylinder Assembly (MTM) on Scion xA?

  A: The replacement procedure for Clutch Master Cylinder Assy (MTM) begins with unattaching the Brake Master Cylinder sub-assy followed by the brake actuator assy and Brake Booster assy and then clutch pedal spring and clutch master cylinder push rod clevis with hole pin while removing clip and hole pin. Cylinder fluid drainage must be followed by unclipping the clutch reservoir tube. Use Special Service Tool: 09023-00100 to disconnect the clutch master cylinder from its flexible hose tube while collecting fluid in a container. Clear the master cylinder clutch assembly through a procedure of removing the two retaining nuts. To replace the clutch master cylinder kit users must remove the slotted spring pin with a pin punch and hammer before taking off the inlet union and grommet while loosening the lock nut and removing the push rod clevis and lock nut. Push the push rod until the snap ring releases and then use snap ring pliers to pull it out from the cylinder body. Afterwards the push rod can be extracted. Handle the piston carefully because it could suddenly emerge out of the cylinder. Pull off both the stop plate and the piston with spring from inside the cylinder without harming its wall. The installation of the clutch master cylinder kit requires applying lithium soap base glycol grease onto parts before installing the piston with spring inside the cylinder while attaching the stop plate to the push rod which leads to attaching the push rod to the cylinder body. The push rod must be pushed forward while the snap ring should go in first then install the boot then fasten the lock nut on the push rod. Install the push rod clevis along with the lock nut prior to putting on the inlet union and new grommet while driving the slotted spring pin. Reinstall both clutch master cylinder nuts to 12 Nm torque before connecting the master cylinder to its flexible hose tube with Special Service Tool: 09023-00100 at 15 Nm torque (120 kgf-cm, 9 ft. lbs.). The clutch reservoir tube needs to be joined to the clutch master cylinder assy through the clip but ensure the assembly remains untwisted with the white mark facing upward. Place MP grease onto the hole pin contact surface and bush contact area before joining the clevis to the clutch pedal assy through the hole pin and then install the clip. The service concludes with installation of the clutch pedal spring followed by the brake booster assy and brake actuator assy and subsequent removal of the brake master cylinder sub-assy. Clutch pipeline bleeding requires filling the brake reservoir tank with clutch fluid at 8.4 Nm (86 kgf-cm, 74 inch lbs.), leakage inspection, reservoir fluid level check and clutch pedal sub-assy examination and adjustment.
