I used to live in this neighborhood and took my '89 pick-up truck to this place a few times. I took my truck for some routine maintenance and fluid checks. When I came to pick up my truck the brakes gave out while driving off the lot. Hmmm. They offered to do fix my brakes and not charge me labor. I agreed to do this - not a smart move looking back but I needed my truck and I wasn't able to drive it. A couple of months later my brakes went out completely while I was driving on the road! Luckily, I avoided any accidents. To be fair, they did replace my brakes (again) at no additional charge. I had gone through too much at this point for that to make much of a difference for me.
I would definitely ask these for these guys to give you the old part if something is going to be replaced. I would also ask for their receipt for any purchase of the new part. I am a little suspicious that they may be using refurbished parts. I will not be using this company again.
I should note this was about 5 years ago. The shop may now be run in a more honest and efficient way today. I really try to support local, small businesses and don't really like giving low ratings. I would just recommend to proceed with caution.
