Hi, The driver side rear pads on my 360R have worn through very quickly after some track days, particularly the inside pad which is down to the metal, whilst the passenger side pads still have at least 5mm on them. It looks like the seal on the driver side caliper is damaged. I'm going to replace the pads with Mintex M1144s. A few questions re the calipers: 1 - Is it normal for the rear driver side pads to wear more quickly? 2 - Given that it's just a Sierra caliper do people normally just replace with a reconditioned unit as I assume there must be loads of them around and if so does anyone know where to get one and what part number I should use? Thanks Gerard
