Quality seems to be exact match to original specs and quality. No instructions included, but the job isn't too bad if you have intermediate mechanical knowledge. Definitely need a set of lock ring pliers unless you like beating and prying around with a flat head screw driver in a very small cylinder! First and foremost ascertain that your old one is actually faulty. You can GENTLY clamp your brake line hose just below the master cylinder using vice grips with a rag or some kind of buffer material so as not to damage your brake line. Then try to pump the brake. If its hard as a rock, yours is good. If it leaks or has no resistance you need a new one. In my case, I bought the new, installed it only to find out that the previous owner had already installed an aftermarket one. The brake components on Honda's are notorious for becoming useless after years of exposure to mud and water.
