I have to replace my rear rotors and while doing so I am planning to replace the brake shoes. The factory sells a one piece unit with shoes, hardware, & backing plate, as well as shoes without the extra hardware. Aftermarket shoes are much lower cost, but I'd like to know if the oem shoes are really that much better. It appears this is true for pads, but would like some recommendations. While doing this, I'm trying to avoid repeating it anytime soon. I will also be checking bearings, seals, etc. Thanks.
