Master Cylinder

The first step for clutch Master Cylinder removal begins with draining clutch fluid followed by separating the clutch reservoir tube from the clutch master cylinder to flexible hose tube through the use of a union nut wrench. Start by uninstalling the front door scuff plate found on the left side and the cowl side trim board located on the LH (left hand) position along with the lower No. 1 instrument panel finish panel. The driver side junction block requires separation prior to disconnecting the clutch start switch connector and removing the clutch pedal assembly containing the clutch master cylinder through two nuts and a bolt removal. Finish by disconnecting the clutch reservoir tube while using a union nut wrench to remove the 2 way tube from the clutch master cylinder assembly. After that disconnect the nut and clutch start switch from the clutch pedal support before removing the clutch master cylinder assembly using 2 bolts.

The clutch master cylinder requires installation using 2 bolts tightened to 16 Nm (158 kgf-cm, 11 ft-lbf). Use a nut to fasten the clutch start switch while torquing it to 16 Nm (160 kgf-cm 12 ft-lbf). Attach the clutch master cylinder to the 2 way tube employing Special Service Tool 09023-00101 and fasten it with 15 Nm (155 kgf-cm, 11 ft-lbf) of torque before adding the clutch reservoir tube. The clutch master cylinder and clutch pedal installation requires 2 nuts then a bolt for attachment to the vehicle body while tightening the nut to 14 Nm (145 kgf-cm, 10 ft-lbf) and the bolt to 24 Nm (245 kgf-cm, 18 ft-lbf). The next step involves joining the clutch start switch connector. Start by linking the driver junction block followed by setting the lower No. 1 instrument panel finish panel, cowl side trim board LH and front door scuff plate LH. The clutch master cylinder must be attached to the flexible hose tube via Special Service Tool: 09023-00101 while torquing to 15 Nm (155 kgf-cm, 11 ft-lbf), followed by connecting the clutch reservoir tube. The technician follows the process of bleeding brake line (without VSC) and clutch pipe line before conducting inspections of the clutch pedal sub-assembly and brake fluid (without VSC) leakage checks and clutch fluid leakage tests and reservoir fluid level inspection.

Use Special Service Tool: 09023-00101, with a torque of 15 Nm (155 kgf-cm, 11 ft-lbf), and then connect the clutch reservoir tube.

Use Special Service Tool: 09023-00101, torquing to 15 Nm (155 kgf-cm, 11 ft. lbs.), and connect the clutch reservoir tube.

Attach the clutch master cylinder assembly with 2 bolts, torquing to 16 Nm, install the clutch start switch with the nut torqued to 16 Nm, connect the clutch master cylinder to the 2 way tube using Special Service Tool: 09023-00101, torquing to 15 Nm, and then connect the clutch reservoir tube.
