This is a Heavy-Duty Combination (Combi) Air Brake Chamber for commercial vehicles equipped with Disc Brakes, most commonly used on the rear (drive) axles of Scania trucks where higher parking force is required. The designation $\text{T}24/30\text{D}$ or $\text{P-DD}2430$ indicates a double-diaphragm (DD) chamber:

• Type 24 (T24): The service brake side (primary braking).
• Type 30 (T30): The larger spring brake side (parking/emergency braking), providing increased holding force compared to the $\text{T}24/16$ chamber.

It is a critical component for the brake system on Scania P-Series and G-Series trucks, including models like the G400-S6 and P380-S5.
