Need some advice/help

[Justy311]

So I recently have been noticing a grinding noise coming from my brakes, I assumed it to be in the front due to it getting louder when I was braking and turning. I brought it to the local Tires Plus and paid $500 to get the rear brakes replaced.

After I drove it home the noise started right back up again. So I brought it back and after they looked at everything I was informed that it is a caliper issue and in order to stop the noise the calipers need to be replaced. Which wouldn't be cheap.

I am curious to know why I wasn't told from the beginning that the calipers needed to be replaced and what might cause this noise exactly as no one really knew. The manager said that the noise is the brakes grinding against the rotors, which is normal and the should go away after a while of driving. I was also told this isn't a concern and not to worry about it as everything is running as it should, will just be annoying.

What does everyone think?
