Mailing to service 1

Hello,

The customer ..... has a problem with their machine’s brake system.
They said that “Sometimes, after we stop the measuring, while machine speed is slowing down, there is a noise coming from the brake unit.”

When I went to service to the customer, I tried seven different fan types with the machine.
I could not see any problem with the brake. There is enough space between the disc and brake lining (please check the Brake.jpg)
But there was some dust from the brake lining on the fan motor cover (please check the Dust.jpg)
But there wasn’t any noise, vibration or bad sound during the time I was there!

Today they called me again. They told me that,
“On Saturday we tried more than 10 different type fans and there was noise with all the rotors.
Today we are working with same type fans but there isn't any problem!”

Could you please share any advice you might have about this issue? Has anyone ever encountered a problem like this before?

Best Regards,
