I swapped out my old CRX master cylinder since it went out in Ohio and I drove it to Charlotte with no brakes and my wife behind me in her civic. When I arrived I put a master cylinder from a 91 4 door civic EX same year as CRX. Stock CRX master cylinder is 13/16 new one is 15/16,it was fine for a couple weeks then I went around a corner at a rapid pace and the brake light came on then it went off and then I had to get on the brakes harder than normal and now the my fricking brake light won't go off disconnect the wires from the master cylinder cap and the light goes out. Anyone have any ideas on what might be going on? I've never heard of a master cylinder cap going bad but I guess it is possible. Anyone who has some knowledge please help

there is a sensor in the cap of your MC..try using your old cap..

 

Old cap was to small

 

May sound pretty lame but did you check your brake fluid level?

 

This is normal because you have a bigger bore master cylinder.

 

That usually only happens if your fluid is too low.

 

Fuild is johny on the spot, but the brake loight didn't use to come on and the first time it came on it went off in a day and was off for 2-3 weeks then when I got on the brakes hard than normal it came on. Is the wiring different anyone?

check and make sure the switch is working on the e-brake.. that can also make the brake light turn on.

 

Not the e-brake checked it, this whole thing just frustrates the crap out of me

 

bump

 

Well then it has got to be a wiring problem or something....
