Component Description

Brake Master Cylinder Reservoir

The brake fluid reservoir supplies brake fluid to the hydraulic clutch system and the brake system. The hydraulic clutch system and brake system are arranged separately inside the brake fluid reservoir. If leaks occur in the hydraulic clutch system, the brake system continues to operate unrestricted.

Clutch Master Cylinder

The clutch master cylinder generates the system pressure required to actuate the clutch. When the clutch pedal is pressed, the piston rod moves the clutch master cylinder piston. The hydraulic fluid in the clutch master cylinder is forced through the high-pressure tube to the clutch slave cylinder.

Clutch Slave Cylinder

The hydraulic fluid forced from the piston in the clutch master cylinder thru the clutch hydraulic tubes moves the piston in the clutch slave cylinder which, in turn, moves the release bearing in an axial direction. The release bearing inner ring presses onto the diaphragm spring. The non-positive connection between the clutch disc and the flywheel is interrupted.

Clutch Slave Cylinder Hydraulic Tubes

The clutch slave cylinder hydraulic tubes provide hydraulic fluid to the slave cylinder. The upper hydraulic tube pulls hydraulic fluid from the brake master cylinder reservoir and distributes it to the lower hydraulic tube after the clutch master cylinder pulls it through. The hydraulic fluid in the clutch master cylinder is forced through the high-pressure tube to the clutch slave cylinder.
