Working principle diagram of oil brake master cylinder, anatomical diagram of oil brake master cylinder

I believe that everyone has a certain understanding of the oil brake master cylinder, which is the main part of the brake system of the vehicle and part of the brake master cylinder. The cars and microbuses we often see use the oil brake master cylinder, but when it comes to its working principle and anatomical diagrams, many small partners just don't understand it. Then we will give you a diagram of the working principle of the oil brake master cylinder. If you want to understand more deeply, of course, the anatomical diagram of the oil brake master cylinder is indispensable.

Working principle of oil brake master cylinder

When the brake is stepped on, the piston and sealing cup in the brake master cylinder will be pushed by the brake pedal, and then act on the push rod toBrake FluidThe oil pipe is transmitted to the piston of each brake cylinder, and then the brake shoe will be pushed to expand outward, causing friction between the brake pad and the inner surface of the brake drum, thereby achieving a braking effect.
