NISSAN 30855-VC20A Clutch Hydraulic Hose Assembly

The genuine Nissan 30855-VC20A clutch hydraulic hose assembly (HOSE ASSY-CLUTC) is an essential component of the vehicle's hydraulic clutch actuation system. This high-pressure flexible hose connects the clutch master cylinder to the clutch slave cylinder, ensuring loss-free hydraulic pressure transfer when the clutch pedal is depressed.

Technical Specifications and Construction

• Material: Premium quality rubber reinforced with synthetic fibers, highly resistant to brake fluid and high temperatures.
• Fittings: Precision-threaded metal fittings at both ends to ensure a perfect, leak-free connection.
• Design: Vibration- and motion-absorbing structure designed to compensate for relative movements between the engine and the vehicle chassis.
• Durability: Excellent resistance to ozone, weathering, and aging for an extended service life.

Function and Symptoms of Failure

The clutch hose is continuously subjected to high hydraulic pressure and harsh operating environments. Over time, the rubber material can deteriorate, crack, or become soft and spongy. Common signs of failure include a soft or sinking clutch pedal, difficulty engaging gears, and visible brake fluid leaks along the hose surface or at the end fittings. To maintain safe and precise clutch operation, a damaged or worn hose should be replaced immediately.
