How to Determine if the Brake Load Sensing Proportioning Valve is Faulty?

[KalebLee]

Methods to determine if the brake load sensing proportioning valve is faulty: decreased braking effectiveness, longer braking distance, and during emergency braking, the rear wheels lock up first, causing the rear of the vehicle to become unstable or even leading to a rollover. The brake load sensing proportioning valve only affects the rear wheels. In contrast, the ABS system can precisely prevent any wheel from locking up, allowing the vehicle to maintain directional control. Higher-end vehicles are also equipped with an ESP system, which can maintain vehicle stability by controlling components such as the ABS and steering gear. The brake load sensing proportioning valve is a hydraulic mechanical device designed to maintain the appropriate load proportion between the front and rear wheels during driving and to ensure that the rear wheels do not lock up during emergency braking.
