Rear brake pad bore diameter — 133.1mm

Tags: #brake-pads · #fitment · #part-number · #mazda-6-compat

The X80's rear brake pad hole (bore) diameter is 133.1mm. Common aftermarket pads sold as Mazda-compatible (brands cited: Zekkert, Masuma, and various other Mazda-branded pads) are typically sized for 129-130mm holes instead. Even this roughly 3mm difference is enough to cause audible clunking in the calipers from the resulting play/slack. Before buying rear pads, confirm the 133.1mm bore measurement rather than trusting a "Mazda-compatible" label alone, since the X80's rear caliper bore differs from the donor-platform Mazda spec ¹²³.
