Ditto. Carguy67, please let us know which after market pads you went with and feedback on their wear. Thanks!

Laszlo... thanks.. but I took it in and showed it to them squealing, I referred them to the TSB and they said that the squealing was due to the brake pads / rotors (pads were down to 10%) and quoted me $1000 to change them. So I changed them myself (1hr and $300), took it back in because it was still squealing in reverse and now they're saying it's because of aftermarket...
I still say the squealing might occur because of the pads rubbing lightly against the disks unlike the spring style spreaders that I saw in the Highlander..
Hope this helps someone, this is the TSB that relates to squealing brakes for 2010/2011 (replacing the calipers):

reversing out of a driveway or parking space in the morning.

I changed my rotors (to Brembo) and pads, and they still squeal when reversing... now my LR dealership is saying that can't honour the TSB as I'm using unapproved parts (so I have to purchase LR pads so they can honour it - grrr).
However, when I changed my girlfriends Highlander brakes and rotors yesterday, I noticed to springy hair clip type pieces of metal used to keep the brake pads apart. However, these aren't on my LR - any ideas if they're supposed to be? Maybe that's why we're getting a lot of wear?
