yep, I'm a computer and control engineer. sorry to tell that my car do not have an ABS system as I knew for the ABS it is a usual for the vibration to show up while ABS is working, but unfortunately my car is not an ABS built system. so I guess it is no the problem!

I have a corsa from opel it is 2007 made 40000 km till now, what I'm suffering from is a break pedal vibrating while I hit the break slightly at high speed over 100 km per hour.

I went to opel dealer "mansour" in egypt and they told me to change the front rotors and front break pad set to eliminate this pedal vibration, and as they said I did change the front rotors and front break pad set.

after the change and repair I still got a vibration in the break pedal when I'm slightly push the break pedal at high speed, so I went back to them again moaning and telling that the repair did not solve my problem.

Guess what ! they now want me to change the rear break drums and break pads, I do not believe that this is the problem and I also afraid that this won't solve my problem.

so what do you suggest me to do ??

by the way I did a wheel balancing and wheel alignment to be sure everything is on the right track. thanks for your help, looking for your prompt response.
