have a 2003 ranger level 2 with the manual transmission. transmission was starting to get a little hard to shift so I figured it was time for a new slave and master cylinders. decided to replace clutch and pressure plate since I had to drop the tranny anyways. got it all put back together and bled the system. everything worked good for about a month and then was having the same system issues as before. re bled the system thinking I didn't get all the air out. tested again and worked fine for about a week and then the same issues started happening. followed a pin point test which directed me to replace the master cylinder. thinking I may have got a bad part I replaced the master again. all seemed to work good for about a month again and then back to the spongy pedal. bleed it again and it will work good for awhile each time I bleed the system and then im back to where I started. its getting frustrating and Ive tried every possible way to bleed the system I know of including bench bleeding the master before if put it in. any tips or insight would be greatly appreciated.

Hey man, did you ever find the solution to your problem??? I am having a very similar issue...Replaced clutch, master cylinder, slave cylinder and bled it at least three times. Each time its fine for a month or so then starts to act up again. Its driving me mad!
