Hi there, I found this by searching for "2001 corolla pad replacement", or similar, in google. I just did the pad replacement today. I didn't turn the rotors, as I think that turning rotors "just because" is a waste of metal and money.
Having done pad replacements on multiple '73-'87 chevy's, rear pads and rotors and a 2001 land rover, and a few others over the years, I must say that this was the easiest pad replacement I've ever done! The hardest part was getting the old rubber piston seal on the drivers side to go all the way back in (and stay in). The passengers side went right in, we (my 13y/o son and I) had that side done in about 20 minutes. It was extremely easy. I appreciate the tips in this article because without it I'd have not known to look for overflowing brake fluid. With a couple of disposable old nasty towels, we kept it from making a mess.
So, thanks for this write-up. The master cylinder fluid tip was worth it all on its own.
