Clutch master cylinders require specific brake fluids, which are formulated to withstand the high temperatures and pressures generated by the hydraulic clutch system.
Here's why hydraulic oil is NOT suitable for clutch master cylinders:
1. Viscosity: Brake fluids have a lower viscosity than hydraulic oils, which ensures proper lubrication and smooth operation of the clutch master cylinder.
2. Compressibility: Brake fluids have low compressibility, which is crucial for transmitting hydraulic pressure efficiently. Hydraulic oils, on the other hand, are more compressible, leading to reduced pressure transfer.
3. Boiling Point: Brake fluids have a higher boiling point than hydraulic oils, ensuring they can handle the heat generated during clutch operation. Hydraulic oils have a lower boiling point, increasing the risk of vapor lock and system failure.
4. Corrosion: Brake fluids contain additives that protect the metal components of the clutch master cylinder from corrosion. Hydraulic oils may lack these additives, leading to potential damage over time.
5. Compatibility: Using hydraulic oil in a clutch master cylinder may not be compatible with the system's seals and gaskets, leading to leaks or damage to the components.
Therefore, it is strongly advised to only use the brake fluid recommended for your specific vehicle. Experimenting with different fluids can compromise the performance and safety of your clutch system.
