I picked up my Ascent Touring on Friday afternoon and there is a grinding noise at the end of the braking cycle. It's at the very end when the brake is fully engaged at a complete stop. Is this normal? My husband said to give it a week to see if it works itself out as things burn off from the manufacturing process, but I was wondering if anyone else is having this issue. Is it normal? Is it just something with this braking system? Thanks!
