  Q: How to service and repair the clutch master cylinder on Toyota Yaris?

  A: Service and repair of the clutch master cylinder starts with unfastening the clip holding the Brake Booster assembly and the clutch reservoir tube to detach it from the clutch master cylinder assembly while collecting fluid with a container. Service the clutch master cylinder by detaching it from the flexible hose tube by using Special Service Tool: 09023-00101 after collecting the fluid with a container. Begin the installation by removing under cover sub-assembly No.1 of the instrument panel followed by removing the clutch master cylinder assembly through removing its 2 nuts. You need to measure dimension A before you start loosening the lock nut for removing the clutch master cylinder push rod clevis. After that you can remove the lock nut. Start the installation process by mounting the push rod lock nut followed by the push rod clevis and tighten the lock nut until dimension A matches the initial measurement. Connect the clutch master cylinder assembly with 2 nuts that require 9.0 N m (92 kgf cm, 80 in. lbf) torque before you link it to the flexible hose tube with Special Service Tool: 09023-00101 through torqueing the assembly to 15 N m (153 kgf cm, 11 ft. lbf). After reconnecting the clutch reservoir tube with its clip to the clutch master cylinder assembly you must reinstall the brake booster assembly then check the clutch pedal sub-assembly before finishing with instrument panel under cover sub-assembly No.1.
