Brake Squeal In Reverse 2013 Rx 350

[dsindm]

I have less than 8K miles on mine and recently noticed that the brakes are squealing when applied lightly in reverse. No similar sound when applied going forward. Anyone else have this? If I take it in, am I going to be told that it's normal? (That wouldn't surprise me, but I would be surprised if it's true; I've never had brake squeal in 100K+ miles of RX driving before.)

Possibly caused by road salt build up on the discs, during the winter my 2011 350 with 40K always makes a grinding noise first thing in the morning when backing out of the garage,so after four years I don't worry about it any more.

Thanks--that could be my problem, too. I'll check it out.
