So far so good
Been on the car for 6 months. No issues so far. Some people complain the studs are loose, mine were but I just tightened them before installing. But some people didn't. Tell me who's fault that is?

Le quedó perfecto a mi Civic 98, lo malo es que duró 6 meses funcionando ...Ya me tocó cambiarlo

Perfect fit but installation may be difficult
The master cylinder fit my 1998 civic perfectly. If (like me) you're not a mechanic, be prepared. The actual installation is very simple. Removing and reattaching the cotter-pin to the clutch pedal may take some time.This is no fault of the master cylinder part. The attachment point to the clutch pedal is in a very awkward position. It requires you to lie on your back at an angle. FYI, as the area is so high up under the steering wheel side of the dash, a good light source will come in handy.I also used my smart phone to record video to locate the exact position of the cotter-pin for removal and installation, as it is difficult to see.Despite my installation difficulties, this is a great deal for the Do-it-yourself folks!

Worked great the first 1
Worked great the first 1,000 miles, then within one day of driving about 20 miles, pedal went down to the floor. Fluid was leaking past the main seal. This is junk!!

So far so good [approx. 500 miles]
I replaced my 17 yr old clutch master cylinder on my acura integra. It works just like a oem part. Great feel and resistance. Was easy to match pedal adjustment. I've only rode for about 500 miles and have no leaks. Will update at a later date.

Works Great On My 1997 Civic
installed this along with a matching Dorman clutch slave cylinder.Exact fit for my car. Installation of both master and slave with all the adjustments were completed in about an hour. After about 3,500 miles, the system still feels nice and firm with no leaks.Very happy so far.
