Difference between the clutch sub-pump and the clutch master pump

The difference between the clutch sub-pump and the clutch master pump is that they have different functions. The following is a detailed introduction:
1. The function of the clutch master pump:
The clutch master pump refers to the part connected to the clutch pedal and connected to the clutch booster through the oil pipe. Its function is to collect pedal stroke information and separate the clutch through the booster.
2. The function of the clutch sub-pump:
1) Allow the engine and the transmission to gradually engage, thereby ensuring a smooth start of the car.
2) Temporarily cut off the connection between the engine and the transmission to facilitate gear shifting and reduce the impact of gear shifting.
3) When the car is emergency braked, it can play a separation role to prevent overload of the transmission system such as the transmission, and play a certain protective role.
