Hello all,
I have a 2007 BMW X5 4.8i (E70), and I have noticed that it is time to change my brake pads. I can see that the pads are super thin now and the brakes squeak when I stop.
My car is at 98k miles right now. I recently replaced a leaking expansion tank, which got me wondering when I will have to replace the brake rotors. I have used OEM BMW brake pads since I picked the car up new from the dealer.
So do you guys think that I need new rotors? And how do I tell?
Thanks.
If those are the same rotors from when you bought the car, I would look into getting new ones. Are you doing the job yourself or at a shop? If you're doing them yourself, check the rotor's outer edge and see if you feel anything, like a small lip; if so then you at least need to sand them down. If you're taking it to a shop, they'll be able to tell you if you need new rotors (check yourself beforehand though). Other members will likely chime in with some advice as well. Best of luck!

You need new rotors. I have yet to find an X5 that's rotors were still in spec after wearing through one set of pads.

Measure the rotor with a brake micrometer. The minimum thickness is stamped on the rotor. And just remember, even if it is above the minimum now, think about how much thinner it will be by the time you wear through another set of brake pads if you don't replace them.
