A friend of mine has a 2002 Frontier, and I have a 2000 Frontier- both with the KA24DE 4 cylinder with a 5 speed. My friend's truck is on it's third slave cylinder - the first one (Duralast) lasted 9 months, the second was a Dorman off of Amazon (I purchased this one for my truck in case of failure, but used it for this repair) and lasted less than 3 months, and the third was (again) a Duralast that was the replacement for the first Duralast (had a lifetime warranty and they exchanged it-no questions asked). The original Nissan slave had a small leak but never failed catastrophically, and was replaced at home. The second and third failures left my friend stranded in places that were not ideal places to be stranded, and in the wee hrs of the night. Both the Duralast and Dorman parts failed in exactly the same way and completely drained the system. The brake fluid within the boots of both failed parts was black, and this was brand-new fluid at the time of installation, since the entire system was bled using the service manual method and using fresh DOT-3 brake fluid. Obviously, these Chinese-made parts do not contain the grade of rubber that can withstand brake fluid - even the lifetime guaranteed one. My friend doesn't want to leave this slave cylinder on his truck and wants it replaced with one that will last. Can anyone recommend a brand that will hold up for years, rather than only a few months? Exedy was mentioned in another thread but we are inclined to go with the OEM Nissan slave cylinder. Since $$ is tight for us both due to COVID, we are wondering what brands of clutch hydraulics have been used by other Frontier owners. RockAuto.com has around 8 different brands (slave) with warranties ranging from 3 months to 24 months. It's disappointing that there are so many critical auto parts of Chinese origin that are floating around, and it seems to be getting more difficult to weed through the choices. Having a lifetime replacement warranty is no guarantee of a quality part, at least with this specific part. This was not the case 30 years ago. Any recs would be sincerely appreciated, since I couldn't find an OEM kit to replace the rubber components, like we used to do with calipers and wheel cylinders.
