No pressure in clutch
 
Well, ive replaced the master and slave cylinder and im still not gettin any pressure in my clutch....theres plenty of fluid...and its not leaking in between the clutch master and slave...i pumped the clutch for abut 10 minutes non stop and no change in fluid and no increase in pressure...im about ready to :Kill1: the dang thing...lol....any suggestions?

Had the same problem. You have to prime the master cylinder. First take the hard line off the master cylinder and plug the hole with the clutch pedal down. Then slowly move the pedal back up. Then when you see the fluid level go down then un plug push the pedal in and you should see fluid squirt out when you push it in. Repeat this about 2 times and then reconnect the hard hose. Pump the pedal about 5-10 times then hold to the floor and open the bleeder for a second untill you see fluid. Repeat this untill you get good pressure or about 5 times. You should regain pressure and the next day you should bleed once or twice more to make sure you got the air out. Hope this helps. You might have to repeat the first step after you try bleeding it again beacuse it will need to fill everything with fluid.

where is the bleeder at?

This would be helpful for me also, I have the same problem but I have not replaced the cylinders. I have been told it would be wise to replace the clutch cable when doing this repair, is this true? And if so what is good to buy or is OEM just fine for an relitively stock car?

The bleeder is on the slave cylinder across from the rubber hose looks like a grease fitting. And there is no clutch cable since it is hydrolic sorry cant spell lol but when you start losing the clutch pressure and replacing things i rebuilt my master cylinder which is alot cheaper only like 12.00 rebuild kit from the mazda dealer and you should replace the rubber line if you see any cracks or suspect a leak cheap and saves alot of hassel. I have not replaced or rebuilt the slave yet but if you have the money you should either rebuild it or buy a new one when you do the master. But the master usally goes before the slave and always cheaper to fix then the slave.

Would rebuilding a master cylinder be within the skill level of an amateur? I have replaced parts before and installed electrinics but I know very little and have no expreience in rebuilding parts like these.

:D If you don't think you can perform a repair it's probably not a good idea a remanufactured master isn't to hard on the wallet, slaves are like $40 if I remember correctly,and always bench bleed new master clyinder...lol

Yea you can bench bleed it but is like the same as i said before you can do it in the car. Just a little messier and dont touch your paint with brake fluid on you hands eats at it. All the rebuild is taking a snap ring out pulling a piston and couple plates and spring and replace with new stuff in the same order the haynes manual goes over it if you have it. It is a good buy. If you want i could give you step by step pics just give me a day. I havent done a slave rebuild but dont think it is much harder.

That would be killer, I really want to learn how to do this stuff but I know that some projects are much larger and more complicated that I would do more harm then good. So yes, absolutely any instructional information would me greatly appreciated.
