hey im new on here and i love xterras this is my second one. i have owned my current one a little over a year. and when ever i apply the brakes hard or at a slight decline or incline i smell this burning smell and a little bit of smoke comes from the hood. i thought it might be a clogged heater but it smells more like burning then a sweet smell and ir only really smells when the brakes are applied. what is it and how do i fix it. thanks for all ur help
