well, you will be surprised just getting rid of the old fluid which contains some water accumulating over time. When brakes heat up heating fluid the fluid will begin to boil the water out...so the with metal lines and the better fluid, it will make the biggest difference...our rotors are well built, I just wanted drilled ones, the stock rotors are really prolly better...the pads are important...I went ceramic...we shall see, may change pads again, but I think so far, they are doing the job...good luck...
