Product Description

Semi-Trailer Parts Spring Single Air Brake Chamber

Product Description

The T3030DD is a high-performance double-diaphragm (DD) spring brake chamber, widely used in commercial vehicles
for critical braking functions. Key features include:

Dual-Diaphragm Design:

Service Chamber: Converts compressed air pressure into mechanical force to apply the brakes during normal operation.

Spring Brake (Emergency/Parking) Chamber: Incorporates a powerful pre-compressed spring. When activated (air pressure released), the spring forcefully applies the brakes for parking or emergency stopping.
Size & Power:

The "30" designation indicates a 30 square inch effective piston area in the service section, delivering significant braking force.

The spring brake section provides robust holding power for parking and reliable emergency braking.

Key Functions:

Service Braking: Applies brakes via air pressure.

Parking Brake: Mechanically engages via spring force.

Emergency Braking: Automatically engages if air pressure is lost (failsafe).
