Dayton Parts 30/30 Type Long Stroke Brake Chamber

The Dayton Parts 30/30 Type Long Stroke Brake Chamber is a heavy-duty air brake component designed for compatible commercial truck and trailer braking systems. This long-stroke spring brake chamber is designed to provide reliable service-brake and parking/emergency-brake operation in demanding heavy-duty applications.

The 30/30 long-stroke configuration combines a Type 30 service brake chamber with a Type 30 spring brake chamber. The long-stroke design provides additional pushrod travel compared with standard-stroke chambers when specified by the vehicle's brake system.

Proper brake chamber selection is critical for safe brake operation. Always verify the existing chamber size, stroke length, mounting configuration, pushrod specifications, and manufacturer part number before ordering.

Long Stroke vs. Standard Stroke Brake Chambers

A long-stroke brake chamber is designed to provide greater pushrod travel than a standard-stroke chamber. This allows the brake system to accommodate applications where additional diaphragm and pushrod movement is specified by the original brake system design.

Long-stroke chambers should only be used when they match the vehicle manufacturer's and brake system manufacturer's specifications. Installing the wrong chamber stroke can affect brake adjustment and overall brake performance.

Why Replace a Brake Chamber?

A damaged or leaking brake chamber can affect the performance of a vehicle's air brake system. Common problems can include air leaks, damaged diaphragms, corrosion, damaged pushrods, or improper brake application.

Replacing a worn or damaged brake chamber with the correct size and stroke specification helps restore reliable operation and proper braking performance.

Fitment Verification

Verify fitment before ordering. Brake chambers are available in different 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 length, mounting bolt spacing, clamp configuration, pushrod length, inlet location, and brake application before installation.
