The brake pads on the 300D are so easy to remove that I have been pulling them off every 8 monts or so and scrape off the rust and scale on the sliding surfaces which inevitably builds up and make the brakes drag. If the pads are even half worn, I get a free set of pads from Autozone and replace them (lifetime pads- I'm on my 3rd set now and Autozone don't seems to mind they are not worn down). I put a little grease on the slides and bleed all 4 wheels till clean fluid comes out. My brakes work great and I haven't had any problems since starting that regimen. I used to let it go till the very end like metal to metal or brakes pulling before I would service it and I like servicing it every 8 months no matter what much better.
