What is the function of the metering and proportioning valve?

The function of the metering and proportioning valve is to regulate brake pressure to each wheel. This is crucial for ensuring that the braking performance is optimized and balanced across all the wheels of the vehicle. The valve plays a key role in the braking system by allowing more pressure to be directed to the rear wheels when necessary, particularly during hard braking. This helps prevent the rear wheels from locking up and maintains vehicle stability.

By finely controlling the pressure applied to each wheel, the metering and proportioning valve enhances overall braking effectiveness, contributing to safe and controlled stops. Perfectly balanced braking allows for better vehicle handling, especially in emergency situations where precision is critical. Understanding the function of this valve is essential for anyone studying vehicle braking systems, as it is integral to maintaining safety and performance on the road.
