Which valve delays hydraulic pressure to the front brakes?

The metering valve plays a crucial role in delaying hydraulic pressure to the front brakes, especially in vehicles equipped with disc brakes in the front and drum brakes in the rear. Its function is to ensure that the rear brakes engage before the front brakes when the driver applies the brake pedal. This delay helps to prevent any potential nosedive or loss of control by allowing the rear axle to compress and settle before additional pressure is applied to the front brakes.

This valve accommodates the differences in brake system designs, ensuring that the braking force is appropriately balanced. By delaying the hydraulic pressure to the front brakes, the metering valve contributes to a smoother and more stable braking performance, enhancing vehicle safety and control.
