Justy L3-1189cc 1.2L (1987)
Fig. 19 Hill Holder Deactivated
When the clutch pedal is depressed, the PHV driveshaft is pulled into the seal, allowing the ball free movement. If the vehicle is facing uphill, inertia
will cause the ball to roll onto the seal, Fig. 7, thereby holding hydraulic pressure. When the clutch is released, Fig. 8, the driveshaft is forced into the
ball chamber, unsealing the ball and releasing hydraulic pressure.
