The valve, also referred to as a vacuum booster or check valve, is fitted to an internal pressure relief valve, which raises the pressure of the booster's brake fluids supplied by the brake master cylinder to an optimal level. As a result, the vehicle's brake lights come on.<br><br><br>The process used in vacuum checking of the brakes can be very simple and straightforward. Firstly, the technician places a portable vacuum check valve at the point where the master cylinder connects to the engine (or wherever the line from the master cylinder ends). These are usually called "crock bar" check valves, because they are placed perpendicular to the crankshaft. A pump or electric motor draws air through the valve and infuses it into the system. If there is no air inflow into the system, then the system does not function, and this is usually a sign of an "inflated" brake master cylinder.<br><br><br>Next, the technician will access the problem area. In some circumstances this can be done with one hand whilst leaning the other arm on the ground. In the majority of cases however, it is most convenient to have both hands on the equipment whilst performing this task, so that the operator can apply steady pressure onto the valve with one hand whilst pulling back on the other hand to lower the vacuum pressure onto the brakes with the other. It is vital that the two hands are placed on the equipment so that they are able to feel what is happening and not against the sides of the pipes.<br><br><br>If either of the above steps do not correct the problem then the problem will usually be deeper in the machinery. For example, a vacuum check valve may be blown out or damaged beyond repair. Severe cases will require the services of a professional technician to replace the valve with a new one.

There are also some mechanical vacuum check valves which cannot be repaired.<br><br><br>Another problem with vacuum check valves is cracking pressure. This occurs when the rubber sealing around the piston area becomes worn. This causes the seal to become weaker and the flow of air in the system is reduced. As the cracks widen, they may even create turbulence inside the system. In extreme cases, cracking pressure may result in the complete failure of the machine.<br><br><br>There are three different types of vacuum check valves. The first is a self-cleaning system which requires no work to be done by the technician and functions automatically. The second is a "ringing" type which requires the technician to manually start the machine and complete the cleaning process once the desired level of dirt has been achieved. The third type is the self-lubricating type which requires lubrication on its working components from time to time. Lubrication improves the performance and prevents slippage and possible breakages. When these components wear out or become damaged, they need to be replaced.<br><br><br>Before a vacuum check valve can be used on any kind of work object, it must be properly set up. The device must be seated on the work object so that the check valve seat faces the appropriate direction. The rubber seals must be properly attached and the valve must be turned on.<br><br><br>You should keep the appropriate brake pedal position when operating a vacuum check valve. This ensures proper braking and increased work efficiency. The brake pedal must be set to "B" if you want your check valve to run all the way to the outlet. The "S" if you want the valve to shut once the desired level of dirt has been achieved. And finally, the "E" if you want to raise the dust limit beyond which your filter won't work.<br>
