Dayton Parts 30/30 Type Spring Brake Air Chamber

The Dayton Parts 30/30 Type Spring Brake Air Chamber is a heavy-duty air brake component designed for compatible commercial truck and trailer braking systems. A spring brake chamber combines service-brake and parking/emergency-brake functions in one assembly, providing reliable braking force for heavy-duty applications.

The 30/30 configuration identifies the chamber size, with a service brake section and spring brake section designed for compatible heavy-duty brake systems. Proper chamber selection is critical for safe brake operation, so the existing chamber, mounting configuration, pushrod dimensions, and manufacturer part number should be verified before ordering.

Understanding a 30/30 Spring Brake Chamber

A 30/30 spring brake chamber contains two chambers. The service brake section operates when air pressure is applied through the vehicle's service brake system. The spring brake section uses a powerful mechanical spring to provide parking and emergency braking force when air pressure is released.

Because spring brake chambers are safety-critical components, replacement chambers must match the vehicle's original specifications and brake system requirements.

Why Replace a Spring Brake Chamber?

A damaged or leaking brake chamber can affect brake performance and may cause loss of air pressure, improper brake application, or parking brake problems. Common signs of a failing chamber can include air leaks, damaged diaphragms, corrosion, pushrod problems, or abnormal brake operation.

Replacing a worn or damaged spring brake chamber with the correct specification helps restore reliable operation of the vehicle's air brake system.

Fitment Verification

Verify fitment before ordering. Spring brake chambers are available in multiple sizes, stroke lengths, mounting configurations, and pushrod specifications. A 30/30 chamber should not be selected based on chamber size alone.

Compare the existing chamber's manufacturer part number, chamber size, stroke, mounting bolt spacing, clamp configuration, pushrod length, inlet location, and brake application before installation.
