Automobile brake pumps mainly include the master brake cylinder and the brake sub-cylinder, which are located in different positions of the vehicle.
The master brake cylinder is usually installed in front of the brake pedal, close to the brake booster pump. The specific location is in the engine compartment, corresponding to the position behind the brake pedal. When you open the engine cover, you can see the master brake cylinder.
The brake sub-cylinder is installed behind the brake disc of each wheel, and each wheel has a brake sub-cylinder. Therefore, the vehicle is usually equipped with four brake sub-cylinders to ensure that each wheel can obtain the necessary braking force.
This layout enables the master brake cylinder to transport brake oil to each brake sub-cylinder through a metal oil pipe, thereby realizing the braking function of the vehicle.
