Front caliper rebuild kit.
http://www.subaruparts.com/diag/?mod...category=262-A Whoops! Link to actual part will not work unless you establish a free account. But it is a good parts site. The caliper rebuild part # is 26297PA010 with price of $29.92 for both fronts. Does not include brake pad anti-rattle clips.
Another online site is
www.1stsubaruparts.com and a member or two on here work at subaru parts places and can give good prices. You can do a search for Liberty Subaru or maybe someone else will come up and give you an addy or name/phone.
It's item #10 in the site and includes kit for both front wheels if you choose to rebuild yourself.
The recommendation for a rebuilt caliper is a good one and besides Autozone you can find them for sale on Ebay.
If you rebuild yourself, you might do a search on here for some pointers on installing the rubber part over the piston. Its a beatch to figure out yourself but very simple following some of the procedures developed by members here.
