I recently had new brakes put onto my 240D (maybe 1000 miles ago) . Recently when i am driving down the road at around 40+ MPH i hear a high pitch squeal coming from the drivers side front tire.

If I tap the brakes, it goes away for a few second, but comes back. If i hit a bump it will also go away for a few second. It only does it when i am going at a consistent speed above 40ish MPH.

Is something loose on the brakes that is causing this? Any other ideas?
