Replaced clutch slave and master one year ago. Yes, I used cheap advance parts because I was unemployed (and will be again next week) The GT has 210,000 miles and now the clutch has stopped working again. The fluid was black and after changing the fluid and bleeding, it's still not working and the fluid is black again. My questions are, can the slave be bad and not be leaking?
Also, is the rubber line still available from the dealer or aftermarket? When I was bleeding it last night (with a mityvac) it didn't seem to flow fluid like it should...
If I have to replace everything who has good parts anymore (at a reasonable price) Someone mentioned buying a slave from Mazda, but haven't those parts been sitting on the shelf for 20 plus years?
Two more hours of this play, somebody shoot me!
I replaced probably 8 or 9 slaves in a period of about 3 years, and two master cylinders. In short time the fluid would always turn black. I used "good" quality Raybestos parts, cheap offshore parts (they were absolutely identical), tried a different brand of brake fluid... they still failed predictably.
Then I changed the black rubber flex line, and it hasn't failed for 2 years - the longest time yet. I also changed from cheap brake fluid to Valvoline. Probably they are the same, but I suspected that the cheap stuff was in part to blame.
You have to get the system absolutely clean - so blow compressed air through the metal lines to blow out all the old brake fluid and abrasive particles.
I became very good at driving without a clutch. It makes stop and go traffic challenging.
If you have a fresh slave and freshly-black fluid, your master is toast.
