I drive a 2013 GMC truck. I get a whine from under the dash when I apply the brakes. I have been advised it is the power brake booster. Any real mechanics here that can shed some light on this issue? I do have a recurring check engine light that comes on goes on its own. Truck stops fine as always. I have not been able to hit the emissions station as the check engine light is an automatic DQ.

Experience is what you get when you don't get what you want.
Pretty sure O'Reilly's auto parts will plug into the ECU for free and read the codes to give you an idea of what's going on with the check engine light
