I bought a 2004 tacoma Trd 5 speed about 6 months ago truck currently has 116k on it. Since then I have had to replace the slave cylinder and the master cylinder for the slave cylinder but I keep going thru master cylinders for the slave cylinder im on my 4th or 5th one ive lost count you can see the fluid turning black from the seals over time in the resivor and eventually the pedal sucks it self down to the floor and it wont shift. the clutch feels good doesnt slip or anything. the master cylinders are coming from autozone and they have given me 2 different brands and with in 4 to 6 weeks they end up going. The oem one I replaced its fluid was black so is it a clutch issue or just cheap junk you get at autozone. the slave cylinder came from napa and i havnt had any issues out of it. Someone please help me im going crazy replacing these things.

Have you replaced both parts at the same time along with flushing out the line?? Its possible you have gotten cross contamination in the system. Replacing one part just to have contamination go from the old part to the new??

when it went the first time I replaced both the slave cylinder and master cylinder and every time it goes I flush the system completely before I reinstalling the new one last week I check the fluid level just to be sure and it was down to the min mark on the resivor put a lil in to to bring it up to the max mark but the fluid was clear. This week I checked it was down to the min mark and the fluid was black and its been around 4 weeks and thats when they usually go
