Recently had front brakes done on "05 Buick Lesabre. Garage said a test strip showed copper contamination in brake fluid, so I agreed to a fluid flush. 2 monthes later, oil change at same garage, they said brake fluid was contaminated with copper, wanted to flush it. Is this a real problem, or are t…

I told him I’d do it (I did), he obviously didn’t like that answer. I open my hood a day later, there’s the brake reservoir cap sitting on the inner fender…

I found this thread to be quite informative. Who would have known the quick-lube class of repair places would have come up with their own official-looking maintenance procedures to sway the customers with. How low will they go? Thanks.
