I'm gonna be replacing the Brake Master Cylinder in my '93 Civic Cx Hatch this weekend and just read thru this very nice DIY thread for the ITR mc/booster swap: https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-jdm-1%22-itr-mc-bb-into-civic-install-818263/

My question is, when removing the old mc from my brake booster...do I need to crawl under the dash and remove the cotter pin from the clevis pin behind the brake pedal? or can I remove the mc from the booster with just the two nuts that attach it to the brake booster from the engine bay?

Thank You & God Bless

 

If it's just the MC, then it's just 2 bolts and two brake lines. Don't forget to bench bleed your MC before installing...

 

Thanks man. Yes...I have my bench bleed hose setup ready to go as well.

Will I need to bleed the brakes after the new mc has been installed and hard lines hooked back up? I just bled the brakes last week.

 

Yeah your gonna need to re-bleed your whole system again

 

Thanks...I figured that...just wanted to be sure.

 

Yes you're going to have to remove and replace that cotter pin.
