Z300 Turbo 1986. I found bits of off white plastic on the drivers side floor. At first I thought my wife had broken something that was nothing to do with the car. However a few days later, more small bits of similar coloured plastic was on the driver side floor. At this point the brake lights stayed on permanent. I have looked at the brake pedal anchor/pivot connection and the throttle pedal. The latter has an off coloured plastic bracket, I assume the brake should have a similar bracket to hold the brake switch. Anyone had this problem, am I correct in thinking the broken plastic bits are a degraded switch holder?
