What is a brake load sensing valve?
The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle.
What is a load sensing proportioning valve?
The brake proportioning valve is located in the brake system for the rear wheels. It functions to control the brake fluid pressure from the master cylinder in response to the vehicle load. It limits the pressure sent to the rear brakes and prevents early locking of the rear wheels.
What is the function of load sensing proportional valve in brakes system?
Maruti Super Carry is equipped with Load Sensing Proportioning Valve (LSPV) braking system that allows better stability during braking along with the front disc and rear drum brakes.
What happens when a proportioning valve goes bad?
Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.
Do you need a proportioning valve with manual brakes?
If I add disc brakes will I need a proportioning valve? Yes. The addition of a proportioning valve is a must. Without it your braking system will not operate properly.
How do you reset a brake proportioning valve?
How to Reset a Brake Proportioning Valve
- Locate the brake proportioning valve near the rear brake line. It will have one or two buttons located on it.
- Push the reset button located on the valve with your fingers, which will reset it so the valve is working properly again. Inspect the brake pressure.
How do I know if my proportioning valve is bad?
First, you might notice your car is taking a nose dive when you suddenly apply the brakes. Then your car may not stop fast enough. If your rear wheels lock up easily, especially when you drive on wet surfaces, it is a good sign your proportioning valve is going bad.
How do you know if a brake proportioning valve is bad?
Can a bad proportioning valve cause brakes to lock up?
A faulty brake proportioning valve may cause the vehicle’s rear wheels to lock up, resulting in a skidding movement as tires lose traction.
Can you bypass a brake proportioning valve?
The valve will only work as designed if the rest of the suspension retains the original specifications – if your car is significantly lowered or the suspension stiffened up, you might as well bypass the proportioning valve.
How important is a proportioning valve?
You benefit by having a brake proportioning valve in your brake system because it helps you control brake balance. A properly-working proportioning valve ensures your rear brakes do not lock-up during heavy braking. This is crucial in any car, but especially in pickup trucks with light backends.
