I can't see how driving style will make any difference to the wear pattern, to me it would only affect the wear rate.Also worth noting these pads where flipped around about 700 miles ago to help balance out the wear but still there is a significant difference. Also the offside pads where crumbling too :surprised: :surprised:

Which pads steve. Were they new, how many miles/tracksays etc
Have you raised this with vwr
SteveP:
DS2500's, not sure exactly how many miles / track days as these are NeilM's old pads as previously mentioned. As QD will confirm mine where far worse when they failed at Spa.
Going to follow it up this week as when I mentioned it to VWR last year they claimed to have never heard of the issue.
QD MBE:
Unless I have my physics totally to cock, and unless there is some artificial means of increasing surface area on the small piston, by clever machining. Or a means of slowing large piston deployment by use of multiple seals, or a pressure reducer - then the large Piston will always deploy first. Pressure acting on a greater piston surface area.
I am sure Dave B will be along to comment.

For the amount of miles, the pads were shocking. Down to the metal on one end, with circa 3-5mm on the other. NeilM's were the same, but the pads were slightly newer, but had signs that they were on the same wear regime.
MAT ED30:
Maybe are better compound pad for track abuse as it looks like the heat has just melted them and they have crumbled but it also looks like your pistons have not been deployed correctly or retracting correctly :confused:
