Brake Proportioning Valve Diagram – Detailed Explanation!

Here you can see a detailed explanation of the brake proportioning valve diagram, and it will be very easy to understand how it works for you. Also, we will cover the topic of how the brake proportioning valve works.

What is a Brake Proportioning Valve?

The brake system of a car is a very important safety feature. With the developing technology of automotive, the brake systems of different automotives also increased. In terms of the brake systems, there are different kinds of additional systems attached to the brake applications. One of these features is the brake proportioning valve.

The brake proportioning valve is a special system that is directly attached to the hydraulic fluid that comes from the master cylinder. The main duty of the brake proportioning valve is to separate the hydraulic fluid actually to all the brake calipers at the four wheels.

If we think about the physics of braking, there will be an additional force or weight on the brake fields because of the deceleration. So the hydraulic fluid will distribute to all calipers, which will not create effective braking for the car. A higher hydraulic fluid or hydraulic force must be applied to the front wheels of the car.

So, to adjust the hydraulic fluid to create the additional adjustments, the brake proportioning valve sends a higher amount of hydraulic fluid to the front brake systems or calipers.

Once the brake pedal is pressed, the brake proportioning valve distributes the hydraulic fluid, which is received from the master cylinder.

And it adds additional hydraulic fluid to the front calipers.

Parts on Brake Proportioning Valve Diagram

You can see different kinds of parts on the brake proportioning valve diagram that do different kinds of work. So understanding the working principles of these different parts will be much easier for you.

Valve: The valve is the first important part. Are you understanding that the first principal duty of the valve is to regulate the incoming hydraulic fluid to the master cylinder? So, the movement of the valve regulates the hydraulic fluid inside the piston and makes the brake proportioning valve system work.

Inlet: As you can see, there is also an inlet from the master cylinder. From that inlet, the braking fluid comes into the system. The inlet is directly connected with the piston system, and it regulates the incoming brake fluid to the valve.

Spring: As you understand, the spring regulates the movement of the piston inside the cylinder. With this movement, it regulates the brake fluid outlet to the rear brakes. Once the piston moves, the brake fluid goes to the rear brakes.

Piston: Also, the piston plays an important role in regulating the brake proportioning valve affiliated with the rear brakes.

Outlet: The last part is the outlet. The outlet is the connection between the rear brakes and the brake proportioning valve.

So, you understand that the working principle of the brake proportioning valve is very simple, and we can explain the different parts of that structure in this way.
