I have a '94 Civic Ex coupe and I want to switch from the factory drum brakes in the rear to disc. I would be doing all the work myself, but what kind of price range are we talking about.

 

5-600 bucks with the correct parts plus new break equip like pads and rotors..

couple of searches will yield you some more specific prices and such. I have not done the swap so i may be a bit over but i think im pretty close..

 

^ditto. I'd say that that would be a higher estimate. You can find rear trailing arms with e-brake cables for 200-300. Then you'll want new rotors, pads and lines, probably rebuild the calipers if they are salvageable otherwise replace them. Oh, and don't forget to get Brake fluid DOT3 or higher.

Now, since you have an EX, you have a 3030 proportioning valve and a 7/8" bore MC. So, you can upgrade to a 15/16" Integra MC (or 91 EX sedan Civic or 88-91 prelude). Also, you can upgrade the p. valve as well, to the 4040 Integra one.

Look for deals.
