I am hearing a low crunching noise (sounds like rusty pieces of metal scraping) while driving, it gets exceedingly louder as I put on the brake. Turning to the right seems to aggravate the problem more. This does not happen when driving in reverse. The brakes and rotors were change about 6 months ago, and had not been making any noise prior to this. It has been extremely cold where I live the past few weeks and the car has been driven through snow and is not kept in the garage. Not sure if that has anything to do with the problem. Thanks!
Crunching noise when braking on 2006 Mercury Mariner
Sounds like the brakes are metal to metal even though they were changed 6 months age its possible the brake pads they used have worn out, go back and have them check their work.
I agree with this guy. Sounds like your brake pads are gone.

This car ( I have a 2005 with 130,000 miles ) goes through brake pads fast - replace them with a reputable srevicer and get a warranty - get the next ones free.
The factory pads delaminate from the pad backing causing a lot of noise. This can be very dangerous if the pad material falls out. Put a good aftermarket set on like Wagner Premium and anti-squeal spray on the pad backs and you won't have problems.
