I have a 2006 Mazda 6s and I just put on new brake pads, rotors and calipers in the back. After I did the work I drove it and noticed a burning smell and my rotors in the back were very very hot. I am wondering if it’s because I have not loosened up my emergency brake since I have all new parts in the back. I am very stuck and am looking if anyone has an answer. Also my e brake is very stiff.
