Hello there. I tried searching

and ended up with a lot of unrelated results.
I passed 60K miles and am preparing to bring my 2013 X5 Xdrive35i for rear brakes and fluid replacement along with the requisite oil change. I am also considering replacing the brake lines with stainless steel brake lines from ECS Tuning. I had the trans fluid replaced at 50K but I am not sure if any of the sleeves were replaced as well.
Aside from the above work, is there anything else I should consider having performed

? I'm wondering about coolant, water pump and possibly other items that could crop up.
I am the 2nd owner and plan to keep it for a while. Thanks!
