While a dealer was repairing a loose turbocharger hose, they called me and said that my car needed new rear brakes. Said something about "metal on metal" and "1mm left", "2mm right". Of course, he wanted to sell me new pads and rotors. Knowing the rate of pad wear from previous DIY maintenance, I doubted that the brake pads really were worn out, so I declined.
So now I measure the brake pads just to make sure, and the results are: 8.5mm left, 10mm right (wear limit is 7mm, so 1.5mm remaining on the left, 3mm remaining on the right). At my rate of brake pad wear (about 1mm per 10,000 miles), this is probably 10,000-15,000 miles before the left pad reaches the 7mm limit.
But why would the left rear brake pad wear faster than the right rear brake pad? There does not seem to be any left bias when I use the brakes, and fuel economy has not changed other than due to recent carrying of roof rack cargo (if a brake were dragging, I'd expect fuel economy to get worse).
So what would the explanation be?
