hey guys m doing a brake job on a 91 accord 4d lx auto trans. im replacing rotors and i have seveeral different sizes available.. 260mm and 282 mm.. which one is it.. can anyone chime in asap.. ?

 

Assuming the stock CB is the same as the CD (they're similar in everything else) it's a 10.2" rotor so the 260mm. The Wagon/V6 had a 11.1" rotor so the 282. You'd need to upgrade the caliper/bracket to take advantage of the Wagon/V6 setup.

You want the 260mm for stock replacement.
