Clutch issue diagnosis help

Hi. I am not familiar with clutches much so im
hoping someone can help me out here a little bit. I’ve got a 93 ranger 4.0 v6. The clutch pedal doesn’t engage the clutch. The days leading up to this happening I was noticing drops of fluid under the truck, which I now believe to be the brake fluid from the clutch master cylinder because my reservoir was empty. I filled the reservoir back up but the problem still persists.

please any tips or advice would be highly appreciated. Thanks!

Welcome to the forum

If reservoir ran dry then there is now AIR inside the hydraulic system
And if you have a leak in the slave or hose you may need to change the clutch now because of the leak

Hydraulic systems work to transfer motion because the fluid doesn't compress, air can be compressed
So in a working system when you press down on the clutch pedal the Master cylinder goes down 1" and the fluid then pushes the Slave cylinder inside the bellhousing out 1" disengaging the clutch disc

If there is air in the system the slave may only move 1/2" so clutch doesn't full disengage, because the air compresses under the pressure

Google: Ford Ranger bleeding clutch

Loads of videos to watch

MAKE SURE to keep reservoir full while bleeding

You can leave reservoir cap off while bleed, there should be NO pressure coming up to reservoir, if so, something is wrong with Master

thanks a lot for that information. I am heading out to bleed the system shortly.

could you tell me if there is a way to access the slave cylinder without removing the transmission? Also, if slave cylinder needs to be replaced and if it does so require dropping the transmission is it the best route to replace the clutch and pressure plate while it’s down?
