The push rod in a Type 30 chamber can extend outwards a maximum of how many millimeters?

In a Type 30 brake chamber, the push rod is designed to extend outwards a maximum of 64 millimeters. This measurement is crucial because it relates directly to the performance of the air brake system. The push rod's extension contributes to determining the amount of braking force applied, and ensuring that it operates within this specified range is essential for safe vehicle operation.

When the push rod extends beyond this limit, it could indicate potential issues such as improper adjustment of the brake system or excessive wear, which can lead to brake inefficiency or failure. Understanding this measurement allows drivers and mechanics to maintain optimal performance and safety standards in vehicles equipped with air brakes.
