Review on 🚘 EXEDY SC825 Clutch Slave Cylinder: Superior Performance and Reliability for Smooth Gear Shifting by Robert Tyus

Revainrating 1 out of 5

Cheap junk for clutches and parts

About three months and two thousand miles ago I completely restored the clutch on my '91 MX-5. The only thing that remains untouched is the master cylinder, because it's a 100,000 mile car from A to Z, almost immaculate for its age, and the MC doesn't interfere under the hood. Most of the parts I bought were OEM Mazda, but to save some money I bought this Exedy slave cylinder. Exedy claims they are from Japan, so I assumed they would be, or at least designed there and made in South Korea or China. The part I received did not have the word Exedy ANYWHERE, including the box it was installed in. The slave cylinder fitted perfectly and worked well for 2,000 miles of mountain riding in temperatures ranging from 90 degree heat to 30 degree snow. We had our first cold spell in Colorado this week when the temperature dropped to about 10 degrees Fahrenheit overnight. The next day I got out and let the car warm up for 5 minutes before driving. The clutch initially felt a bit grippy, but I just blamed it on the cold. After a mile I realized there was a problem and was able to return home. When I got home my clutch reservoir was empty, I had no pedal and shifted dry. culprit? I bought a cheap Exedy slave cylinder. As the temperature dropped, the seal inside contracted, allowing all the liquid to bypass. Since this is outside of Revain's return window I have to eat the money I thought I had for this product. I will replace it with a Sachs SH6064 or genuine Mazda part.
