I have spent the past three weekends trying to get my 93 ford ranger fixed the clutch isn't holding pressure and is barely building any the parts that have been changed already is the slave cylinder and the master cylinder both are hooked up correctly and everything is lined up it is not leaking any fluid and when the hose is disconnected it still will not build up pressure any help

i own a repair shop and on these you have to gravity bleed them ,that's the only method that will work on getting the pedal back, i been at this for 36 years,and i have seen so many people ruin a brand new cylinder on these trucks ,if you have pumped the new one, chances are its is ruined,its called dry pumping,and it ruins them you have to take and loosen the line if it is one that doesn't have the bleed on it,and it takes a few hours to get it right,there's no fast way to get it back that's why so many people screw new cylinders up ,they want the clutch to work right away,and it wont,it has too be gravity bleed out,and at no time let if go dry in the main cylinder on it keep an eye on the fluid at all times this is the only way you,ll ever get it right ,like that factory one worked on it,good luck with it hope this helps.

Buy a brass plug for the clutch master. Remove the hydraulic line and insert the plug. Then pump up the master and bleed it from the brass plug. If you do this a few times and you can't get pressure in the master cylinder, even with all the other hydraulics disconnected, then the master is bad.
If you DO get pressure in the master, then either you have air in the lines or the slave cylinder is bad.
If you are very clever, you can drill a small hole in the filler cap of the master, and buy a can of compressed air and some clear hose, and send compressed air into the top of the master cylinder and bleed the brakes that way.

these are very difficult to bleed, the reason why is the way the master is positioned in the fire wall, it cause air to be trapped in the end of the master. the easiest way I can tell you to do it will involve taking the master and the line to the slave off and bleed them as an assembly. this way you can keep the master tilted where the air can be removed, you will need a helper. fill the reservoir with fluid and keep the master at the lowest point and the end of the slave line at the highest point. on the end of the line is a check valve that is closed unless it is plugged into the slave, you can open it with a small rod or screw driver. open the valve and have your assistant stroke the master to the bottom and hold it and you release the valve, the release the master, repeat this until no more air comes out, 2-3 times usually, and the master can no longer be pushed with the valve closed. reinstall on the vehicle and bleed the slave and you should be good to go. this is a bad design and really sucks. good luck.

your slave cylinder is bad i had a '93 ranger with a 5 speed in it the design of the cylinder itself leads to it's failure this was fords way of making things easier but they failed it is a common problem on any ford truck with a manual tranny get a new slave cylinder bench bleed it before you install it this will help evacuate some of the air install it and it helps to have a couple extra people one to pump the clutch one to fill the master cylinder and you can open and shut the bleeder screw they are a bear to get the air out of i did 3 of them on my truck in 5 years it may take a bunch of cracks of the bleeder screw just have plenty of brake fluid on hand and don't let the reservoir go empty or u will have to start all over again ....hope this helped

I had the same problem when i changed the clutch in my car.
I put a new clutch kit, new slave and master cylinders. Bled the line for hours and hours, could not get any pedal! Turns out after much headache the new master cylinder i bought was bad. I took it back got a replacement and I had pedal in 5 minutes.

Did you "bench bleed" the master cylinder before installing it?
It's probably still got air in it.
Air compresses, and won't allow the fluid to push on the slave cylinder.

You may have air in the lines. Or it could be the shifting cable itself or even the clutch cable. Look at either of these and go from there.

Dos your truck have a vacuum assist break?
You may have to start your truck before you bled your clutch.
