The clutch bracket shouldn't matter. The clutch cable on my crx isn't held by anything, it's just attached right into the tranny. If it's not the cable itself that is damaged, then u could either have these problems:
1. The cable just needs to be adjusted. Go to the tranny, look for the clutch cable(it's black and has a large plastic nut right on the arm that the cable is attached to), and tighten the nut. Double check the adjustment after your done.
2. The clutch pedal itself is broken. This was the case for me a coule months back. I replaced EVERYTHING, b4 realizing that the pedal itself was the culprit. Look under your dash and check to see that your pedal is operating okay. Look at the little cylindrical post that is right where the pedal "pivots". If it's broken, then the pedal won't get leverage to pull the clutch out, so replace it. It's only like 30 bucks or so at a junk yard. Any 89-91 civic or crx pedal assembly will work. I think 90-91s had better pedal assemblies, so try them first.
3. Worst case scenario, the clutch release arm is broken from inside the transmission. It's not hard to actually remove the arm from the transmission, but this means you have to drop the transmission out to get to it. PITA. Try other things first, and if they all check out, then you'll have to inspect your release arm, or even the clutch itself.
Hope this helps, good luck!
