I've not been able to find an on-line catalogue for Bendix pads. When I bought some last year for the rear brakes of my 2015 car, they weren't right when I looked at them in the shop.They were missing the pips on the back to stop the caliper piston rotating. It was exactly the same with a box of Brembo pads and another brand. So, I wouldn't put too much faith in cross-referencing systems motor factors use. If I knew what the Bendix part number was and could look at a dimensioned drawing of it I would have saved a wasted trip. In the end, I bought some Pagid pads where were a proper fit, and came with new shim plates.
In comparison, the original Hyundai pads are better quality. The backing plate is stamped more cleanly with nice squared edges and radiussed corners. I unbolt the yoke from the hub and clean up the slots that the shims clip into, to remove rust and scale. The pads are a pretty tight fit anyway so another 0.5mm of rust can make the difference between sliding and jamming. When fitting the pads into the yoke, off the hub, it's a lot easier to see where they may be tight spots around the pads that could do with filing down.
