the dreaded clutch problem

well there i was, making my way home from the monthly meet on weds night and suddenly the clutch pedal starts making its way to the floor. ok...was mostly highway driving, so wasn't much of a hassle...but as i came nearer home and had to pull away from stop streets...damn...a lot of pumping could just about make enough pressure for one pull away.

so yesterday went down the local spares shop and got a generic mazda slave kit for $3.50 and installed. nope..problem persisted...so this morning going to get a master kit and see what happens. such a nice and simple system....just hope i can get it working again

better replace the rubber hose that goes between the mc and sc while you're at it...should work just fine after you replace the mc

Hydraulic clutches can be difficult to bleed. Replace the flexihose for sure. Also helps to bench-bleed the MC before installing. Sometimes you might need a power bleeder, there is a long thread somewhere about this subject. One guy made a power bleeder out of an old bicycle inner tube instead of paying $20-$60 for one at the autostore. You can also try a "speed-bleeder" which is a bleeder nipple with an internal check valve, but I've had problems getting the right thread size.

another $3.50 for the master cylinder kit.

all installed and working ok so far.

also adjusted the pedal slightly....clutch used to take quite high up..my knee hit my cheek when i pulled away....now it takes a little lower down.

thank goodness mazda kept the sizes of these things the same for like the last 25 years....else where would i have gotten the spares ?

This sounds like what happened to mine except I wasn't driving. Some of you may remember this from my posts a long time ago...

The car has been sitting for many years, and now the clutch pedal is stuck down. Do I need to replace the clutch cylinders? If so how much do they cost? Also how do I get to them to replace? Sorry again for being a newb to mechanics. Thanks in advance ~John

blackdragonauto.com has both for relatively cheap. I had to go to them for the slave and master cylinders not all that long ago. That way you don't have to worry about making sure to get them cleaned out hardcore before putting them back on, and its pretty much just bleeding the air out of them as well. Perhaps I am just a lazy bastard, or perhaps I am too ****, but I would much rather have everything new and already put together than having to take it all apart, put new parts on the inside of an old part and then put it back on. Even though I know there really can't be anything wrong with the old pieces you would keep.

Anyway, if you get a rebuild kit you should do more than just replace internal parts, like hone out the cylinder bores.
