I didn't have the discs and pads replaced recently. It was about a year ago that they are replaced. There was no such feeling before. This feeling happened recently. How can I check the break servo is really gone? I havePP2000, can I check it with PP2000? Thanks.

You are right sir but I did many tests before driving it.

Here is the video. www.youtube.com/watch?v=ECabV0Q3R5g

I couldn't capture the noise because it appears only while driving. I was not safe to adjust the camera while driving. When the car is stand still, it disappears.

What do you think?

When the car is stand still, there seems no problem but after driving some time, the noise starts coming and the pedal is becoming stiff. I guess I need to capture a video while I am driving otherwise it is hard to explain.

I will drive my car tomorrow and take another video for the noise. I will ask my wife's help at this time. The brakes are working well, so there is no safety issue for now.

The noise starts after driving let say 15 kilometer till the car stops. It is not continuous noise, it happens only when I apply pressure on the pedal. It is not like "air being sucked through a small hole" either. It is best to wait till I capture another video of it because it is hard to explain. If I try to explain I would say, it sounds like the noise is coming from the spring of the brake pedal which needs some lube but I am not sure because it would behave similar even the engine is not running. On the other hand, I feel the pedal becomes stiff whenever this noise occurs. Another issue is that the hydraulic level is increased. Not too much but increased instead of decrease. I could clearly see the siege when I look from the top but now I can't see because it is full of fluid now. This also makes me suspicious. Why does hydraulic level increase?

I appreciate your helps. I will look forward hearing your comment after uploading my new video tomorrow(European time).

Thanks.

I don't think that the reservoir cap is incorrectly fitted.

I have taken another video for the noise. Note that this noise only appears after driving around 10 kilometers (depending on how many times I applied brake). The video is captured while I am driving arond 20-30 km/h till reaching the parking spot. In the video, I am pumping the brake several times to show the noise, otherwise it is not my tradition to do it :)
