Wrong...

only Canadian civic ex's have rear discs.

US ones have rear drums...

unless it is a SI...

most people swap the rear disc's from 94-00 integras. or 92-95 civic Si's.

I have a pair of E-brake cables off a 93 Si if you need them.

The Ex's have bigger front rotors. and bigger Rear drums then other civic models.

looks like you can use the ebrake cable off most civics...
