Question On 3rd slave cylinder, why do they keep leaking?

I bought a 1990 pickup recently had it for about a month now. About a week ago the slave cylinder blew going down the freeway. I bought a new one and was working great for about a week. Then that one started to leak out the rubber boot where the rod comes out to push on the arm to disangage the clutch. So I replaced that one and now today it did it again. So does anybody know what the problem is I did a search on here and google and could find nothing. I havn't replaced the master yet because the stock one looks like better than the one I got from napa. Thanks in advance and sorry for any spelling mistakes I'm posting from my phone.

Quit using non OEM hydraulics.

Go to the Toyota dealer and buy one. They're on 40-50 bucks.

Is it a big difference? I got it from napa from my buddy who works there for 18 bucks lol so I figured I'd try it. Anyways I have a napa master too if I put that in would it counter it since they are both crapier lol?

It could be poor quality control in China the cylinder might be machined to big or the inner parts to small.

Unless some how you are over pressurizing the system some way.

Advance auto parts hydraulics are a big no-no. I have had this same trouble with brake and clutch cylinders. Best is to get OEM, whether from Toyota or the actual manufacturer. AutohausAZ.com has some high quality units. I believe Adler is the actual manufacturer of many Honda and Toyota hydraulics (have one in my Accord, it's got a couple years of use with no issues after the Autozone one crapped out in 6 months).

If you still have the OEM slave, check to see if the price for a Toy rebuild kit would be cheaper. They are fairly easy to rebuild, just get a honing tool from NAPA.......

make sure your pedle is not adjusted all the way out...when does the clutch engage high or low? if its to far out you could be overextending the napa slave
