CLUTCH? problem. i need HELP
I'm having some problems with the fc i just bought. I took it to a mechanic for a checkup and he said i may need a new master clutch cylinder. My friend noticed that the clutch pedal felt a bit soft and he recommended i tighten my clutch plate. The car already had problems grinding (sometimes) when i put it into gears (especially high rpms and while racing around and reverse gear). I took it to another mechanic to change the tires and do their full check up and he didn't notice anything wrong. The next couple days later my clutch or something started messing up bad and when i put it into gear, the car bounces around, like when you let off the clutch too fast. It also hardly accelerates, regardless of wot. Tonight it felt somewhat normal again. The clutch pedal feels soft (but it's my first manual car, I've only borrowed my friends honda's and occasional other cars in the past), and the whole pedal does nothing except for the last like inch or two before it's fully released and it's hard to have the car throttled enough because it's hard to tell where the action of the clutch is since it only has like an inch or two of action at the very end before you release it. I told the guy I bought the car from over the phone this story and he thinks I need a slave clutch cylinder!! Everyone says something different and I don't know what part(s) to replace!
It would be very, very helpful if someone could offer any advice on what needs to be done? I would like to put on a nice clutch (possibly a top of the line racing clutch) as my car is fairly modded.. what would a good clutch be and what else could the problem be??
THANK YOU VERY MUCH!

if you dont like the freeplay your car has you can adjust it with the rod behind the clutch pedal.
but like the two said in front of me might was well replace the mc and sc.
and also if you are goign to replace the clutch disk,which you have to take your tranny out to do, you would need to replace the pilot bearing and throw out bearing.

^^ I suggest you read the OP post again.
Change the clutch fluid
Change the tranny fluid
Inspect or replace the shifter bushings. These bushings are common to go out and cause grinding. I had a customer recently want to trade in their rx7. They were told they needed a new tranny cause it wouldn't go into 5th and reverse. I told them to put in new bushings. WHOLA went in to reverse no problem. It's a cheap fix to. Mazdatrix has a great write-up with pics. REALLY EASY TO DO!!!

Thanks a lot for help... The problem became worse after posting this thread. I had to shove it into first. I put in a new slave clutch cylinder and that became a bit better. When I took the old one off it was loose as hell. So I'm going to change the master and try the bearings cause it grinds in 3rd and reverse and 1st now too. I also tightened the clutch pedal and that helped a lot. My car is becoming slower and slower!!!!!! How come?? It's like it's half as fast and everything was great a couple weeks ago. I have intake, exhaust, piping, headers, new valves, plugs, cables, and some other stuff. It was all solid but now my car is way slower. What gives?

If the master cylinder is leaking, time to get a new one. I would never trust rebuilds since the old cylinder is probably too f'ed up anyway.
If you do get a new master, make sure you get either OEM Mazda, or Tokico (They make the OEM Mazda cylinders.) Do not go with a parts store discount cylinder, those are usually all rebuilt, and will have problems MUCH MUCH sooner than the OEM. Mazdatrix sells the Tokico cylinder in their clutch hydraulics section. (www.mazdatrix.com)
If it was a problem with the slave, your fluid would still be pushing through, but the slave wouldn't do anything (i.e. make the throwout bearing disengage the clutch). You would have a hard time shifting; you'd have to float the gears (shift without the clutch). Actually, those are the same symptoms as a pilot bearing seizing on the input shaft.
Your symptoms definitely sound like a leaking master cylinder or a cylinder that's on the verge of failing. Make sure the clutch is properly bled and that the fluid is at a sufficient level. You should have barely any pedal play. If you still do have play, you probably should order that new cylinder, as well as a new clutch hose. (might as well) For the hose, a lot of people get the SS braided line. (myself included) However, after reading about it more, you find out that, because the SS line has less expansion than the stock OEM line, you punish your hydraulics more. I think the best line to get is just the stock OEM replacement.

When you said the car feels slower and slower does it seem like your rpm's are going up and you are hardly accelerating then there is a possibility that your clutch is slipping causing the car to accelerate slower(I have the same issue on my 300zx) so you would need a new clutch. What is your cars mileage, what mods have you done and how much boost are you running. If your making enough power the engine is more powerful than the clutch can hold causing it to spin slower than the engine (hence the word slipping). The only way to fix this is to buy a stronger clutch.

valves?
what valves?
when the clutch is depressed (IE when you are going in gear and all) is the car revving but not going faster? or is it just like the car has no power?
clutch could be slipping and thats not good
