I have been told on this forum that brakes on mountain bikes don't see the temperatures required to glaze a pad

Also I have no idea how my mate did it, but he saved a pair of pads that he dropped in a bucket of mineral oil after he bled his brakes and went to put down the new pads he got. He put them down in the waste bucket He said he did a quick buzz with the blow torch (like 1 or 2 secs) then boiled them in water then cleaned them with metho. He finally sanded the surface a little bit (just to get a cross pattern) his brakes feel fine and he said he never needed a break in period for them
