    Hello,

    I am about to buy new brake pads and rotors and on the O'Reilly website it says that the rotors do not come with an ABS Sensor Ring. Is this a problem because I am pretty sure that my 2015 Prius has ABS brakes.

    For reference, this is the link to what I am trying to order:
    BrakeBest Select Brake Rotor 580704RGS | O'Reilly Auto Parts (oreillyauto.com)

    BrakeBest Organic Front Brake Pads D1184A | O'Reilly Auto Parts (oreillyauto.com)

    Thank you and regards,

    I think the ABS sensor ring is on your drive axle and your sensor penetrates the hub in a 10 mm bolt I think holds it in and doing pads you should not have to touch any of that at all when you do wheel bearings that's another story.

    The rotors do not have the sensor rings. They are on the hubs.
    The OEM pads are best. Not sure about oreilly's....

    Why are you replacing the rotors? How many miles do you have?
    I have over 321,000 miles on my 2010 and still have the original rotors...

    If I keep the original rotors, do I need to resurface them? O’Reilly will resurface rotors, or do you recommend that I take it somewhere else?

    Thank you,

    As long as there is no pulsations when you are braking, you should be good.
    They rotors are pretty thin. There probably isn't enough to resurface them without
    going past the minimum thickness.
    Is there a lip on the outer edge? How many miles on them?

    You do not need rotors. Unless the yare messed up. I'm surprised you need pads so early

    Unless you brake hard all the time, there probably isn't a lip.
    But with less than 113,000 miles, I doubt you have a lip. How thin are the pads?

    And a small lip would be normal. It's hard to say without seeing them.

    And it depend on how YOU feel about it.
