This is what mine are like. 95% of my driving is motorway miles and I always leave a decent gap and slow down in advance approaching junctions, roundabouts etc, so am very light on the brakes. Once in a blue moon I will have a 'spirited' drive, where and when it is safe, nothing silly though and only for a couple of minutes, so no way should they get hot enough to get damaged like that. Have checked the caliper and it is fine. I will be following the advice on here and contacting EBC. This is the type of thing you would expect from dirt cheap ebay pads, not from a supposed premium brand with matching prices.
