Question

The positions of the brake valve which are normally used when graduating off the brakes are?

1) 17
2) 99
3) Cannot be fixed
4) None of the above

Answer 1

The positions of the brake valve that are normally used when graduating off the brakes can vary, but two common positions are 17 and 99. These positions refer to the angle or degree of rotation of the brake valve handle.

Step-by-step explanation:

The positions of the brake valve that are normally used when graduating off the brakes vary depending on the specific system being used. However, two common positions are 17 and 99. These positions refer to the angle or degree of rotation of the brake valve handle.

For example, in some air brake systems, the handle is typically placed at position 17 to begin the process of releasing the brakes. As the operator continues to rotate the handle, the brake system gradually releases, allowing the vehicle to start moving. In other systems, the handle may be placed at position 99 to begin this process.

It's important to note that the positions of the brake valve can vary in different systems, so it's always best to consult the specific vehicle's documentation or the manufacturer's guidelines for accurate information.
