There's also that place called Brake Check on Centre Street and 16th Ave NW across the street from the New Asia Supermarket. I haven't been there myself but my uncle has and tells me to go one day.
I was told that if your brakes needed work they will let you know otherwise if its still in good working condition you don't need to get it fixed. Looks like there are only 3 of these in Calgary.
