What is the requirement for brake systems during vehicle inspection?

The requirement for brake systems during a vehicle inspection is that they must pass a performance test. This is essential because brakes are a critical safety component of a vehicle, and their functionality must be assured not just by visual inspection but also through practical testing. The performance test ensures that the brakes can effectively stop the vehicle under various conditions, which is vital for safe operation on the road.

Visual checks alone do not provide sufficient assurance of brake performance, as certain issues, such as brake fade or uneven wear, may not be visible. The performance test evaluates the braking system under load and measures the stopping distance and effectiveness, ensuring that the brakes are in good working order before the vehicle is deemed safe for use. This comprehensive approach to inspecting the brakes is crucial for maintaining road safety standards.
