Nothin' to it. just release the cable pop out the pin and install. The brake is a piece of cake. The clutch is a little more difficult. I replaced my levers with the Kury "trigger" style & really like them.
I replaced my rear brake lever with a new billet piece a couple of weekend ago. Everything came apart very easily. The only difficulty I had was to get the cotter pin back into the clevis - this took me about a half hour of jiggling and jaggling, but it eventually went in. Also, you will be working close to the rear of your front fender, so watch where your hands and tools are at all times - and your watch, rings etc. - I nearly dinged my fender a few times. Good luck - you should have no problems.
