I agree... I would just call Discount and price the caliper. Tell her to call herself and find out just how bad she got ripped off....

Why did she stop for break work anyways? Was it grinding? Did you notice that side was worn worse? Really, they probably promise her a free check? Then.... Oh Ms. ...... We can't let you leave. It would be unsafe and I could never do that in good conscience.
She got ripped off....
