so i have a 89 crx si with disk brakes, and a daily driver 97 Del Sol Si, the crx has rear drum brakes while the Del Sol has rear disks. I was wondering if i could swap the rear brakes off of the cars and have them work fine on both cars but the crx would get the disks and the Del Sol would get the drums?

 

I don't know about trying to take the later disc brakes to the CRX but I have done the CRX rear disc swap onto a CRX rear drum car and i definitely don't thingk it was worth the effort in an level of improved braking. I have had CRX racecars with both drum and disc rear brakes and I honeslty don't know of any braking advantage otehr than the drums will periodically need to be adjusted up and the rear discs don't. The CRX drums have a much bigger swept brake lining area than do the disc pads.

In my garage for years I have had the parts to do the CRX rear disc conversion and both my street CRX and my racing CRX still have the drums and I have no plan to change that.

My vote is to save your effort on this and put your money and time somewhere that you will get a real perforamcne gain. BTW, I did swap my '89 CRX street car up to the larger front discs and calipers from the '91 Civic EX/'90-93 Integra and that was much easier and made a strong improvement in braking. If you want to make a brake swap for teh CRX, that would be my suggestion.

 

It will botl up fine, but you will need DA/EF disc ebrake cables.
