How hard is it to replace the ftont and rear brake pads on my 2004 A6 Quattro and how do I make sure they'll be noise free and squell free. My local repair shop charges nearly $450 to replace them. Also which pads are best for low wear, low dust annd low noise.

 

Also I'm going to try to start maintaining my A6 myself. How hard is it to change the oil in a 2.7T. I'm tired od $110 oil changes
