Have to ask a few questions before i do this rear disc swap on my CRX. Would it be wise if i just did the Si conversation or the Da and just put bigger rotters on the rears? Also is there any write up on how to do the rear disc swap. What all is involded in doing this swap. Anything i should look out for or beware of??
IF you want to do the Si rear disk swap i can help you out. And the DA swap should be pretty much identical. You will need the complete trailing arms from an Si, including: brake calipers + rubber brake line, wheel bearing+rotor, e-brake cable. First go to the store and buy brake fluid, PB blaster, and some kind of bolt lubricant (also new RTA bushings and brake hardware like rotors or pads that you might need).
Block front wheel and support the rear of the car with jack stands (or use a lift)
Start on the car by disconnecting the rubber flex brake line from the steel line using a 10mm flare wrench. Make sure you have a little catch container to catch the fluid that will run out. There is a slide clip on top of the little L-bracket that holds the end of the rubber line in the L-bracket, remove this too.
Next, using a 14mm socket and a 17mm socket you simply unbolt the Dx trailing arm from the front toe adjuster bolt, bushing bolts, the UCA, the LCA. Now the only thing holding you in are the e-brake cables.
Go inside the car and remove the little front access panel on your e-brake cover. Us ea philips screwdriver to remove the two screws and slide the cover back and out. Unbolt the plate holding the ends of the two cable housings with a 10mm socket. You should be able to free the cable end nubs now. Go back under the car and you will need to remove the rear exhaust heat shield cover, its like 4 or five easy but annoying 10mm bolts. now feel for where the e-brake cables run and you will have to unbolt three 10mm bolts per side that are placed annoyingly between the underbody nd the gas tank edge. its slow goign and annoying but you have to do it. Once done push the ends of the cable from inside the car through their bushings/holes and pull them out through the bottom.
Do both sides and reverse the order to install the Si or DA assemblies. Don't forget to change your prop valve according to your front/rear brake setup before refilling the system, bleeding the brakes and hitting the road.
