Was trying to figure that out...I have receipts just have to find it..but thinking 6 years plus. The rotors could be turned so I may hang onto them, calipers never seized but the part of the piston outside of the rubber seal needs to be cleaned/polished to see if they are ok to reuse. Bearings were ok but will toss them, brake pads were done. So if I can save the rotors and calipers the next time will be cheaper. Cost me $1500.00 with my discount for complete kits which came with new mounting plates, bearings, seals, buddy bearings and the end dust caps.
