I am so glad I have seen this thread! Thought I was going crazy! My front wheels squeak exactly as described. Mine only started when I had the discs and pads replaced in April this year.

I got the mechanic who did the work to look at it several times and every time he came back to me and said he couldn't hear the squeaking and it wasn't the brakes! I took the brake pads out and roughed them up a little, the squeak stopped for a few days, then it came back with a vengeance!

Seeing as I only had the pads replaced in April, they obviously haven't amended the compound since this thread started! Can anyone recommend where I might be able to find some brake pads that are not the squeaky ones, or what I should be looking for?

Worth mentioning:- Squeaking/squealing noises while driving/accelerating, or more noticeable turning left/right . There is a nut at each of the suspension lower ball joints, located behind each wheel. One of the nuts was turned the wrong way, touching the wheel plate. Definitely not the wheel bearing as this fault creates high pitch screeching. Wheel bearing is low pitch whining noises. Check the lower suspension behind each wheel.
