Another factor that has accelerated brake wear (especially rear brake wear) in certain late model vehicles is the change to electronic brake proportioning. The proportioning valve that normally reduces hydraulic pressure to the rear brakes has been eliminated so the rear brakes will handle a higher percentage of the brake load and be more aggressive. The antilock brake system performs the job of brake proportioning by keeping an eye on how the rear brakes are behaving. If the rear brakes start to lock up when braking hard, the ABS system kicks in and cycles pressure to the rear wheels to prevent them from skidding.
This approach helps the vehicle stop in a shorter distance, but also increases rear brake wear dramatically. This means the rear brakes will often wear out before the front brakes.
现在讲究performance的车设计都是后轮先刹,甚至一松油门,后闸就开始工作,这样才够Sporty

传统conventional proportioning valve, 前轮是会快点。我相信GLk是aggressive的新设计
