A. The service brake chamber (Fig. 6a) performs the normal slowing and stopping function. B. The parking/emergency brake or "piggyback" chamber (Fig. 6b), mounted in tandem on top of the service brake chamber, contains a diaphragm (or piston) and a large powerful spring. WARNING: Do not attempt to service or disassemble the spring chamber

How does a brake cylinder work?

As the driver activates the brake pedals, the outlet valve of the triple valves shuts, and the inlet valve opens, permitting the flow of compressed air from the reservoir through the brake lines of the system. These streams of compressed air traverse the brake lines, ultimately reaching the brake cylinder, housing a piston.

Brake master cylinder: function, failure symptoms, and

Master cylinders are used in both disc and drum brakes. They convert the pressure applied on the brake pedal into hydraulic braking power. This is done by the brake master cylinder feeding and controlling the brake fluid into the brake circuits, depending on the force exerted on the brake pedal. By efficiently converting the force applied to the brake pedal, it ensures that your vehicle

Retired spring brake actuators should be safely disarmed before they are disposed of to prevent serious personal injury from accidental sudden release of the high-energy spring (which can generate as much as 2700 lbs. of force) in the parking chamber. Coils of the power spring should be cut with an acetylene gas torch prior to disposal.
