“1.1. CLUTCH PEDAL”
“The clutch pedal is connected to the hydraulic master cylinder by cross shaft, bell crank, and push rod components assembled to the driver control module. When the clutch pedal is depressed, fluid pressure is built up in the master cylinder, forcing fluid into the clutch servo, which causes the clutch release fork to move. The release fork and release bearing compress the pressure springs of the clutch to disengage the clutch disc. When the clutch pedal is released, fluid pressure is relieved from the hydraulic clutch system, allowing the clutch spring to force release fork and release bearing to return to a position of engaging the clutch disc. Springs in the master cylinder and pedal linkage assist the pedal return.”
“NOTE – Technicians must verify which clutch type the vehicle is equipped with to determine required service.”
“Clutch pedal free play is the distance of travel the pedal makes before any action takes place. Clutch pedal free play cannot be used as an indicator for clutch adjustment with the hydraulic clutch actuation system.”
“1.2. MASTER CYLINDER”
“The clutch master cylinder converts pedal force to fluid pressure for system operation. When pedal force is applied to the clutch master cylinder, the piston displaces hydraulic fluid through the hydraulic hose to the clutch servo located at the transmission clutch housing. When clutch pedal is released, fluid returns to the master cylinder, allowing the clutch to engage.”
“1.3. RESERVOIR”
“The reservoir is remotely mounted from the master cylinder in a location accessible for service. The reservoir supply hose should maintain a downward slope from the reservoir to allow trapped air to escape and to allow fluid transfer to and from the master cylinder. As the clutch wears, the release bearing position moves toward the clutch, gradually increasing the amount of fluid in the reservoir. The fluid level indicator MIN/MAX is printed on the reservoir – DO NOT OVERFILL RESERVOIR. The fill cap includes a vent to allow trapped air to escape and has the warning USE ONLY DOT 3 OR DOT 4 BRAKE FLUID printed on top of the fill cap.”
