Valeoscope - Clutch Hydraulics CSC CMC CRC 998123

5. Hydraulics design and composition

5.9 Comparison of the all-plastic hydraulics versus aluminum and cast iron components Until 1995, the clutch hydraulic release system was composed of a master cylinder in aluminum and a cast iron release cylinder connected to a hydraulic hose made of steel and rubber. The weight of the subassembly was about 1 kg (2.2 lbs.). The full function (with bearing, fork, guiding tube) weighs about 1.7 kg (3.75 lbs.).

From 1995, hydraulic clutch release systems were revolutionized and with the widespread use of plastic materials and of CSC, the weight of the function and cost are considerably reduced with less risks of corrosion. The total weight of the CMC, the hydraulic hose and the CSC is about 0.4 kg.(0.88 lbs.).
