I have the 4 wheel rear disk brakes from JimK. I noticed on the rear driver's wheel, brake dust on the rim which is not on the other 3 wheels. I used my IR temperature gun to read the tire and wheel temps at nearly every fill-up and none have been out of normal. Last time when we got home, I shot the temps of the caliper and disk itself and found them all to be reasonable consider I just braked from hyway speeds. In Celsius, low 50's for the calipers and mid 60's for the disks. The rear driver's disk was hotter, but within 5C of the others.
The pads don't look excessively worn. If it was dragging I would expect it to run significantly hotter.
Any ideas?
Thanks
