Clutch Pedal Inspection And Adjustment

1. | Measure the clutch pedal height (from the face of the pedal pad to the floorboard) and the clutch pedal clevis pin play (measured at the face of the pedal pad.)

Standard value
Stroke (A) : 142~148 mm (5.5905~5.8268 in.)
Free play (B) : 6~13 mm (0.2362~0.5118 in.)
Height (C) : 216 mm (8.5039 in.)

2. | If the clutch pedal free play and the distance between the clutch pedal and the floor board when the clutch is disengaged, do not meet with the standard values, it may be the result of either air in the hydraulic system or a faulty clutch master cylinder. Bleed the air or disassemble and inspect the master cylinder or clutch.

Bleeding
Whenever the clutch tube, the clutch hose, and/or the clutch master cylinder have been removed, or if the clutch pedal is spongy, bleed the system.

Use the specified fluid. Avoid mixing different brands of fluid.

Specified fluid: SAE J1703 (DOT 3 or DOT 4)

Concentric Slave Cylinder Air Bleeding Procedure

1. | After disconnecting a cap from the concentric slave cylinder air bleeder, insert a vinyl hose in the plug.

2. | Loosening the plug screw, press and release the clutch pedal about 10 times.

Hold the air bleeder body not to rotate with a spanner(A). The holding is needed when the plug loosened or tightened.

3. | Tighten the plug(B) during the clutch pedal pressed. Afterwards, raise the pedal with a hand.

4. | After pressing the clutch pedal 3 times more, loosen the plug and retighten it with the pedal pressed. Raise it again, then.

5. | Repeat the step 4 two or three times. (until there is no bubble in the fluid)

Tightening torque :
(B) 6.9~9.8N.m (0.7~1.0kgf.m, 5.1~7.2lb-ft)

1. | Do not clamp the pipe of a concentric slave cylinder.

2. | Be careful not to damage O-rings.
