Abstract
A pneumatic drum brake system for a cultivator trailer consists of several components, including the brake drum, brake shoes, pneumatic actuator, air compressor, air reservoir, and control valve. Once the brake pedal is pressed by the driver, the control valve releases compressed air from the air reservoir into the pneumatic actuator (slave cylinder). The actuator converts the air pressure into mechanical force, which pushes the brake shoes against the inner surface of the brake drum. This generates friction, which slows down and stops the trailer. The brake drum is attached to the cultivator trailer's wheel hub and rotates with it. The brake shoes are mounted on a stationary backing plate and positioned inside the brake drum. They are curved to match the contour of the drum's inner surface, maximising the contact area between the shoes and the drum. The air compressor is responsible for supplying compressed air to the system. It draws in air from the environment and compresses it to a much higher pressure, which is stored in the air reservoir. The control valve regulates the flow of air between the reservoir and the actuator, depending on the driver's input (pedal pressure). Overall, the pneumatic drum brake system provides a reliable and effective means of controlling the speed and stopping the cultivator trailer, particularly in heavy-duty applications where high braking forces are required.

The student presented the thesis and answered the reviewer's questions, after which the committee members asked the following questions.
Question 1: How was the 500h inspection period estimated?
The student provided a sufficient answer.
Question 2: How heavy is the frame (own mass), particularly when the axle is solid?
The student failed to answer.
Question 3: What was the calculation strategy? What were the assumptions?
The student failed to answer.
Question 4: Can your present the drawing documentation?
The student provided a good answer.
