Damaged servo – symptoms of brake element failure

However, before we move on to the failure of the brake servo, let's determine what this element is actually responsible for. The servo strengthens the entire braking system; Thanks to this, using the brakes does not require so much force. The lack of a brake servo would mean that the stopping distance of the vehicle would be much longer , which in turn translates into a greater risk of collision and other undesirable situations on the road. The servo is most often located under the hood of the vehicle - from there it generates additional force that allows the machine to stop faster.

How does a servo work? This part is equipped with two parts separated by a membrane. If the driver decides to press the brake pedal, a valve between them immediately opens and air is sucked into one of them. The negative pressure in the second part presses on the diaphragm ; a rod attached to the brake system assembly runs through its center, simultaneously connected to the master cylinder piston. When you press the brake pedal, the diaphragm stretches the rod mentioned above and increases the pressure on the master cylinder piston. These two forces cause the car to slow down quickly.

Brake master cylinder failure - symptoms of problems with the brake servo

This element is crucial in the context of security . Therefore, it is worth being able to recognize the situation in which it fails. Symptoms of a damaged brake servo include a stiff brake pedal and its high position. Another characteristic feature is the prolonged braking of the vehicle and poor operation of the entire drive unit. All the symptoms mentioned above should trigger a warning light; However, the situation when the stopping distance of the vehicle becomes longer is particularly dangerous. If the vehicle does not stop relatively quickly after pressing the brake pedal, you should consult a mechanic as soon as possible.

There is also a method to check the servo yourself. To do this, pump the brakes several times. When starting the drive unit, simply press the brake pedal : if you feel that it is completely stiff or that its tension does not change at all, there is almost certainly a brake servo failure. This item will need to be replaced quickly.
