EF9 comes with rear disc brakes from the factory.

Yes it does, but in his profily he clearly says he has a crx si with a b16 engine, which leads me to assume its USDM and not JDM, which would not make it the ef9. Yea, use the crx trailing arms, also use 92-93 integra GS-r e-brake lines and yes, take off the heat shield from the exuast and you will be under there for a while.

I installed my braykes in a couple hours. They were the breaks off a DA, but I didn't get the E-brache cables, so it was a quick install.

can you use the drum brake lines with the rear disc conversion? (the hydraulic lines themselves, not the parking brake cable)


EDIT: I searched, and you must use the integra or CRX 90-91 si lines, they are different than the drum brake lines.

i put on DA rear discs on my hatch today. the e-brake lines are by far the hardest part of it all. the da e-brake lines fit perfect! the holding brackets even line up perfectly. i do think it makes my wheels sit outward a little more.

I did a before and after alignment with my rear disc.. even if you leave your compensator arms alone, DA rear disc do knock your rear toe out of alignment. on mine it was nearly .2degrees on each side.

guys, do you not know that the da spindles bolt right up to a civic ef rear trailing arm, thats what i just did and it works perfect, dont waste your time puting the da trailing arm on. it is so simple and i can not believe that any body had not reviewed this on HT !!!!!!!

i used the crx BRAKES..(HAPPY NOW??) yeah, so they just bolted right up....im still waiting for the rain to stop so i can go to the junk yard and pick up a few caliper bolts and the hydrualic hoses to connect the caliper....ill take picz and post them to show you how they look. the arms are exactly the same. drum and disc. i just got some from a CRX Si 1991, it fits perfect...i dont see how the camber is going to be affected.

the camber isnt affected.

i finally put my front DA brakes on day.. ive got 3 alignment sheets now.. pre-any work, da rear disc, and full da-brakes. ive found that 99% of the information regarding da brakes and their affects on alignment are WRONG.

First off, rear DA disc will affect your rear toe regardless of whether or not you mess with the compensator arms. the camber and caster are not affected. the DA rear disc DO move your wheel outward approx 1/4" and can cause rubbing problems.

Front DA brakes also knock the toe WAY off. i had 1.5degs toe in on each wheel for a total of 3 degrees cross toe when i converted! Caster is NOT affected. However, the DA front brakes caused my camber to become even more negative than it was previously, contrary to what everyone on here says. ive notice nearly no change in steering effort or feel.

hope this helps to clear some of this information up. i will try and come up with a way to post the three alignments i did to show the affects of the DA brakes.
