Dear Sir,

I would like to explain my problem with my ML320 Year 2002. I face a problem with strong whistle sound coming from my car while I’m braking this sound make me headache and other drivers the sound is very bad I visit Mercedes Benz workshop three times the first time they skim the pads and the disk, in the second time they replaced the pads and disks. Driving my dream car changed to make headache for me and others, every time I reduce the speed or stop at traffic signal drivers looking to me wondering what’s wrong !?
Who a car of this brand name and luxury make a noise like this .
Any Advise to replace the Brake Pads with better quality production .

Thanks.
