Pdf brake is an essential feature in order to retard and stop the railway vehicle within minimum possible time. There are really 2 individual cylinders in a single unit. Brake fluid is one of the most important components of a brake system because it ties all of the other components into a functioning unit. Brake fluid is a specially blended hydraulic fluid that transfers pressure to the wheel cylinders or calipers. Such advanced systems as antilock braking systems abs, the electronic stability programme system, and the antislip control system assist a driver in ensuring.
The use of a direct means of actuation, such as hydraulic pressure to apply the brakes is but one method of brake actuation. The connections are such that the left front and the right rear brake are on one circuit and the right front and left rear are on the other circuit.
