About this How-To:
If you want to have more stopping power, it would be a good thing to have rear disc brakes as part of your setup. Unfortunately, unless you have a 99-00 Civic Si, you are out of luck. Here you will see how I converted the 99 project hybrid Civics' rear drums to discs. I would like to add a few things. First, I did not end up changing the master cylinder (even though I bought it) over to the Civic Si's because of time constraints. The sizes are nearly identical on the 6th gen Civic EX (may also be on the 5th gen Ex's) however on any other model it should be considered mandatory that the master cylinder be changed otherwise your rear disks COULD lock up if you hit the brakes during a turn causing you to spin out. I would also like to say that halfway through doing the mod, it started pouring and the rain was getting in my garage so we got a little lazy with the camera and didn't take as many pics as I would have liked. Also a note for the install, I didn't think about it until I was halfway through the install that I received the wrong rear stainless steel brake lines. I got the kit for a Civic EX even though I ordered the one for the Si and I had to use the lines that are for the front brakes on the rear instead so as of this writing I have the stock rubber lines on the front and the steel (front) lines on the back. They will be replaced shortly. I would rate this as a medium difficulty install. Expect to spend half the day or more.
