A couple of hundred above 63000 kms on the ODO. So basically, the rear FF disc pads served this much. Actually, out of the rear 4 pads,only one was in very bad shape rest were still fine. On the other side, the front were not original so the previous owner must have got them changed.
InshAllah I'll update on the performance of the pads as well. 
Lol... Return them to me. I'll put them on my bro's car. 
Well, the credit goes to @aqibracer as it was his suggestion. 
You can get it done and can remove if it looks odd. Iss mai na ziada mehnat hai na paisay.
