Conventional wisdom says, "when you replace your disks, put in new pads too" and goes on to say that this is to stop a pad that's been shaped to one disk having poor contact with a new disk.
Nowadays, with pads that are harder than the disc, can (or indeed, should) this be reversed?
I took a shufti at 'er indoor's Escort (97, 50k, all original parts) and the pads are still very meaty and look to have little wear on them while the disk is getting near its limit (20mm down to about 18.5 - min allowed 18mm.) The disks will get replaced soon but I'm trying to see any point in replacing the pads as, if they're that hard, they are going to "shape" a new disk to their wear pattern in the same way that the hard disks of yesteryear shaped softer pads, no?
Any comments (apart from the safety lobby and the penny pinchers association, please)?
