What is a brake chamber that includes both service brake and spring brake sections called?

Service brake chamber
Spring brake chamber
Hydraulic brake chamber
Dual brake chamber

The correct answer is: Spring brake chamber

A spring brake chamber is a brake chamber that includes both service brake and spring brake sections. A service brake chamber has a single diaphragm for applying the brakes, while a spring brake chamber has both a service brake section and a spring brake section for parking. A hydraulic brake chamber is used in systems that use hydraulic pressure to activate the brakes. A dual brake chamber is a type of brake chamber that has two separate sections, typically used for heavy duty vehicles to improve braking performance. However, a spring brake chamber, as the name suggests, incorporates both service and spring brakes, making it the correct answer in this case.
