Features

  • Boston Gear CMBA Series brakes feature a double C-face design for enhanced compatibility with various motor configurations. These brakes have an automatic reset function, ensuring seamless operation in case of power interruptions. They come with a manual override, allowing for manual control when necessary. These CMBA Series double C-face AC brakes offer a spring set capability, providing added safety and stability in critical situations.
  • The brand's CMBWB Series AC brakes. They have bidirectional rotation capability, allowing versatile operation in both directions. These brakes have electrical activation, providing precise control and automation. They feature a straight design, optimising efficiency and reducing friction for smooth operation.

Working Mechanism

  • An air brake utilises compressed air pressing on a piston to apply pressure to the brake pad or shoe.
  • A compressor creates the compressed air, while an air dryer prevents moisture particles from entering the air braking system.

Frequently Asked Questions

What is the air brake test?

    The Seven-Step Air Brake test is a procedure designed to assess various aspects of the air brake system.
  • Ensure the governor allows the air compressor to start pumping air when the pressure falls to the minimum level.
  • Confirm that the governor cuts out the compressor when the air pressure reaches the maximum level.
  • Check for leaks in the air brake system by observing the pressure gauge for a steady drop in pressure.
  • Verify that the warning buzzer activates when the pressure falls below a safe level.
  • Evaluate the functioning of brake valves to ensure proper operation.
  • Assess how quickly the air pressure rebuilds after the brakes are released.
  • Confirm that the yellow and red valve is pushed in (on = valve out), indicating that the brakes are disengaged.

What is brake stroke for air brakes?

Brake stroke refers to the distance in inches or millimetres that the pushrod travels when the brake is fully applied. If the pushrod stroke exceeds the regulated limit, the foundation brake might not be capable of providing full braking force, indicating the need for brake servicing.

Are these Boston air brakes safe in fault conditions?

Even if there is a leak in an air brake system, it causes a vehicle to slow to a stop at worst. This design positions air brakes as a safer alternative to traditional hydraulic brakes, particularly for larger vehicles.
