I have a 93 dx hatch.I bought it from a close friend.He originally bought the brakes from me.I got them from a guy who said he doesn't know what they are from but that all integra/civic/crx si rear disk brakes are the same.Its time to change the pads and rotors and i don't know how to figure this out.I have done many swaps,timing belts,and my own maintenance and have owned 10 hondas/1 integra type R.so don't be mislead if i sound like a noob. Any help would be appreciated
