Vehicle is an 09 Mazda B series. The gear changes seemed off in regards 2 my clutch pressure & within 3 uses of the clutch all pressure was gone leaving the pedal on the floor. There's still plenty of grab in the clutch & the normal level of fluid in resiviour(max). Now releasing from placing in first, the clutch grabs straight away when peddle is released only an inch of the floor, foot back on & peddle to the floor the clutch is not working nearly at all & feels like its grabbing & Iam unable to select neutral. I turn the engine of & then I have sum clutch back & am able to select neutral without a problem.
Probably bad clutch master cylinder and/or slave cylinder. I always replace both.
Its possible air is in the bottom cylinder as to why and what if it slightly rusty it may need honed or take som 320 wet and dry sandpaper take ccylinder {lower One)off take piston out of cylinder twist the sandpapper eround something to size and push it in the bor twist it and maybe clean the bore with only rubbing alchohol put th sandpaer back inthe bor and twist it till you hav little cirle scratches and rust is gone (clean) wash the piston with the rubber seal cup in alchohol dry it then put brake fluid on it and stick it all back to gether youl then need to re bleed the system try pouring it in and useing your hand to pull the peddle back up wait a few seconds between down and up bleed cylcle if it dosnt buil peddle get a turkey surrenge put brake fluid in it hook a little hose from it to the bleeder zerk have t open 2 turns squeez the fluid back up the bottom cylinder it will go to top cylinder (make shure peddles up when) when several ouces are induced this way close the zirk on bottom then work the slave cylinder clutch peddl up and down by hand it will become hard and stay up by its self then you fixed it and dint spend much cars like porsche have to be bled this way period

Two things, first does it slip at all? If you put it in high gear and hammer it, does the engine rev up? If so, you may have a spring problem causing the clutch to not fully contact the pressure plate and will result in this problem.
Is the fluids in the master cylinder full? Do you have a leak? Bad pressure? I'd check those before going on to more difficult remedies.
Personally, by the way you're describing it, I'd say it's a spring. Especially since it's engaging and disengaging correctly. Maybe an adjuster somewhere came loose? I'm not sure with the Explorer, but I know my friends `00 F-150 had an adjuster snap causing a very similar problem but the clutch just wouldn't grab at all due to his problem.
WITH ENGINE ON & RUNNING and you are able to shift to any & or all Gears and with this theres,
No Clutch Engagement Upon Releasing Clutch
With Info Provided seems that you have 1 or all 3
of the Fallowing and they all Should be Replaced as A Set even if on lt 1 of them has Failed
All Require Removal Of Transmission this is the reasoning for Replacing all as SET with the Labor cost if your replace only 1 Item, and 3 Months later another of the 3 components Fail, you have the same Labor cost to PAY.
This Solution is Answering the SOLE Question ask, Barring No other Problems have or did Happen such as Noises Ran out Of Trans Lube. if it is the Clutch that has Failed and you are unable to Perform the Repair yyourself, DO SHOP AROUND get 5 or more Estimates as the Fee Will Vary Sometimes very wide gaps in fee's
and also Try and Purchase the Parts yourself Due to the Tremendous Markup of parts at Shops
I Hope I have Answered you Question to your satisfaction and if you have any more questions Feel free to Ask Me

ok, this is a pressure plate issue. i would check the throw out bearings as well. its always good to do this when it is disassembled.
SOURCE: Clutch has no resistance, stays near floor after applying pressur
I had this same problem on my last 91 accord. You most likely have air in the line. I had to bleed the line for the master cylinder, and then refill the clutch popped up right off the floor. As long as it is not continuious then I would try this. All I needed was a wrench. and i didnt cost me anything. Hope this helps, if you buy the book it will show you how to do it, just look under clutch it will show you how to bleed it. Good Luck.
