Information about FOOT BRAKE VALVE

FOOT BRAKE VALVE
The foot brake valve is responsible for preventing panic braking that can result in a vehicle's ride height increasing, causing the rear to lock up. It can also help prevent rear-wheel lockup by regulating pressure to the rear brake system. When you notice this, your next step is to get the valve replaced. It is critical to properly diagnose a failing valve, because it may affect the proper operation of your braking system.

The foot brake valve is installed in the air-braked vehicle, and is usually mounted on the fire wall or floor. It controls the amount of air in the service line, which controls the force of brake application. Foot brake valves come in three different types, Type A, Type B, and Type E. These three components all work together to minimize lag when applying brakes. When you step on the pedal, the foot brake valve opens and actuates the brakes.

The air brake foot valve is a perfect replacement for a dual braking system. When the pedal is depressed, the foot valve begins the braking process. Its tough materials can handle the harsh operating conditions and lasts much longer than the competition. The gongzheng air brake foot valve is an excellent option if you need a foot brake valve that works in any vehicle application. You can easily get one with a cross-reference listing.

There are several symptoms of a faulty ABS modulator. These symptoms mimic those associated with brake hoses, calipers, and master cylinder issues. Common complaints include a pull-back sensation when braking, long stops, and a low pedal. One possible cause of these symptoms is that the valve seats or pintles are stuck and contaminated with debris and corrosion. In addition, brake fluid may also become contaminated with debris and cause the valve to stop working properly.

When determining whether a replacement brake valve will work with your vehicle, it is important to check the ratio feature. This refers to the relationship between control air pressure and the brake valve and the air delivered to the service brake chambers. Normal stopping uses a 1:1 ratio, while hard stopping requires a 1:1.5 ratio. Both of these conditions can be corrected with a valve lap-off. To make sure that a replacement brake valve will work in your vehicle, look for a cross reference listing.

The ratio of brake valves is one of the primary characteristics of a hydraulic braking system. Specifically, the ratio means that when the vehicle is pulling a trailer, the brake pressure on the steer axle is reduced. This can greatly improve braking performance. Some brake valves are internally or externally piloted. Using the ratio can help optimize the operation of variable pump controls. This information can be helpful when determining whether your vehicle should be fitted with a ratio valve.

A proportioning valve, also known as a braking force regulator, connects the master cylinder to the rest of the brake system. These valves are essential for optimizing front-to-rear brake bias and brake balance. As fluid pressure builds, the plunger in the proportioning valve unseats and the spring compresses, blocking the fluid flow. The goal is to maintain an even pressure distribution for safe braking performance.

A proportioning brake valve is designed to mimic the original braking system. While it has no internal parts, it may contain an internal adjustment that controls the braking force. Properly matching the proportioning valve to your vehicle will help it function optimally under any conditions. However, it's important to remember that adding a proportioning brake valve to your vehicle won't solve all of the rear-bias issues that you may encounter. A properly matched proportioning valve is a good option if your vehicle is equipped with an electronic proportioning valve.
