Hi all-

I have an Impreza WRX 03 and recently I've noticed when I apply the brakes at a moderate speed I get a mechanical spinning sound which I believe is coming from the engine bay.

I had a friend of a friend replace my rear wheel bearings a couple of days ago and this is when the noise started.

Has anyone experienced this noise or know what I;m talking about?

Also it seem as if there might be some slippage in the brakes.
