QUOTE(kkk8787 @ Oct 4 2020, 05:01 PM) Wait I think im getting u. U mean the pad is actually 2 pieces joining together rather than 1 single piece so when u use it till the end u can see the joint. But somehow the joint is zig zag actually it started life as 1 piece...it's stuck to the plate, then a groove is cut into it about 80% deep... this is the line you see on new pads the bottom of the groove is a stress concentration point...over time, it develops this crack you're seeing now... so it's correct the crack is zigzag a bit but follows the big groove line correct...you use past this 80% depth, you'll just see this crack line |
