What kind of oil should be applied to the brake pump piston?

Brake pump piston should be applied with grease. The following is an introduction to the working principle of the brake pump: 1. When the driver steps on the brake pedal: the main pump piston moves forward to close the bypass hole. Oil pressure is then established in front of the piston. The oil pressure is then transmitted to the brake sub-pump through the pipeline. 2. When the brake pedal is released: the main pump piston returns under the action of oil pressure and the return spring, and the pressure of the brake system decreases. After the piston returns, the excess oil flows back to the oil reservoir. 3. When braking with two feet: the oil in the reservoir enters the front of the piston through the compensation hole, increasing the oil in front of the piston, thereby enhancing the braking force when braking.
