Quick facts
- Part: Bosch 15010127 brake rotor
- Also called: disc brake rotor
- Fits: 2012-2015 BMW X1 and other vehicles

A worn rear rotor can show up as a pulsing brake pedal, a grinding noise, or deep grooves with a raised lip at the outer edge. Worn pads or caliper trouble can bring on a pulse or grind as well, so during a brake service, measure the old rotor's thickness and look for cracks before replacing it. The engraved edge code on this rotor gives its identification and discard spec. Both rear rotors are normally replaced together, and this listing is one.
Fits
Cars this rotor fits include the 2012-2015 BMW X1, the 2007-2013 BMW 328i and the 2009-2013 BMW 328i xDrive. If your BMW isn't one of these, look it up by year and engine under the "Vehicles it fits" section.
