    Brake Chamber :
    Air brake chambers are round metal containers , located at each Wheel , where compressed air is converted into mechanical force to apply the brakes and stop the vehicle. There are two kinds of brake chambers ; service and spring brake chambers. A service brake chamber contains a flexible rubber disc called a diaphram,a metal rod called a pushrod and return spring. When you pres brake pedal, compressed air fills the service brake chamber,causing the diaphragm ,push out the pushroad and a return spring. When you press the brake pedal, compressed air fills the service brake chamber,causing diaphragm to move and push out pushrod to apply the brakes. When air pressure is released, the pushrod is returned to its originial original position by the spring inside the chamber. The pushrod and a lever ‘called a slack adjuster’ link the brake chamber to the brake assembly ( which contains the brake drum or disc). When you press the brake pedal , the pushrod extends farther from the brake chamber, moving the slack adjuster forward. The motion of slack adjuster transfers to the brake assembly, causing the brake shoes or pads to make contact with brake drum or disc. The action of the pushrod extending from the brale chamber is called pushrod stroke, and stroke lenght is distance that pushrod travels out of the chamber. In the most common brake designs, some of brake linkage , components linking the brake chamber to the brake assembly is exposed. As a result , the lenght of pushrod stroke can be measured and compared to prescribed adjustment limits for that size , type and style of brake chamber. The pushrod stroke is dependent on pressure of compressed air that enters the barke chamber. For example, when application pressure increased from 69 kPa (10 psi) to 552 kPa (80psi), stroke increases noticeably . Due to design of brake chambers, each has a limited pushrod stroke lenght capacity , beyon which no brake force is produced. The brake linkage includes a device adjust the position of brake chamber in relation to the position of brake shoes. As brakes wear, the linkage must be re- adjusted to ensure the pushrod storke is always within it’s normal operating range. This type of brake re adjustment is required ar regular intervals. Since the drop in brake force can be significant when stroke exceeds and adjustment limits of a brake chamber, it is critical that brakes are correctly adjusted to ensure function is retained. Any brake exceeding the adjustment limit is a defect that requires prompt attention.
