Hi guys my evo 8 is making a very werid noise in the left front, it's not happen all the time
everytime this problem occur, I can heard some kind of vacuum noise,
just like som small thing on the rotor,
but if I brake at this time, there will be a seriuos clunk noise from the left front,
I can even feel vibratile through my brake pedal
just like the ABS, but it is not.

I took it to a local mechanic
all pad, rotor, wheel bearing are good, this makes me more confuse of the noise
mechanic said maybe one diff pump is not working and ask me to change oil and see how it goes.

have anyone seen this problem before...
so scary to heard I need to spend very much money to fix it..

hope anyone can give me some ideas.

Regard
