I had a bad vibration whenever i would apply the brakes so i thought it was the front rotors. well i took it to a repair shop and they told me the rear drums and shoes needed replaced and also the front rotors needed machined and new front pads put on. they gave me a quote of $675 out the door. that just seems a little inflated to me or is that about right for the work being done? I have a 2006 chevy silverado LT ext. cab. They did tell me that they were very surprised that the rear drums were worn down so low since the truck is fairly new.

That sounds high to me but this is the kind of thing that dose not have to go to a dealer. Shop around for a better price. Check with independent brake and muffler shops. Do this by just calling them and asking what it would cost to have the following work done; front rotors machined, new front pads, rear drums and rear brakes. To be on the safe side also ask about the price to replace the front rotors as sometimes you have to replace them too if they are too far gone’ worn, gouged or warped. Make sure you are comparing the same work at each shop and also get information about the warranty (many places offer life time parts but may gouge your on labor when you come back). Once you have the shops rated by price and warranty go the one of your choice and have them give you a brake inspection and tell you want needs to be done. You don't want to be the one telling them what needs to be done unless you are 100% sure of the needed work. If there are big differences in prices for the work on the front and the back between shops you can have one shop do the front and the other do the rear brakes Depends how much effort you want to invest in gathering prices. Just be sure the shop tells you want needs to be done. By the way, the vibration that was your original problem is most likely warped front brake rotors.
