Had our 2006 LR3 for about 2 month, and I have a re-occuring issue with the driver's side rear getting hot. I can smell it when I park in our garage, and the disc is very hot to the touch, like burn your finger instantly (don't ask me how I know). The issue first happened about a month ago, so I took it to a local shop to fix that and the parking brake banshee scream. The issue went away, but now is back. Any troubleshooting tips? Things I can look for?
