Which one is yours? Listen first

Grinding when you brake — If the grind appears or sharpens when you press the pedal, it's brake pads worn to the metal — the dominant outcome.
Grinding while rolling — A grind or growl that's there whether or not you're braking, and that changes on gentle swerves, is a wheel bearing — the second-largest family in these visits.
Grinding on turns — Grinding or clicking mainly in turns points at a CV joint running dry inside a torn boot.

What to expect from the shop

Expect the shop to separate braking grind from rolling grind — the pedal test does it in a minute. Braking grind is pads to metal with rotors likely; rolling grind is a wheel bearing; grinding on turns a CV joint. Ask which, and for the wheels to come off before the quote.
