I've got a '93 F150 with the 4.9L. As I was driving my truck to work this morning, I had an issue with the clutch. I got in, backed out of the parking space, put it in first, then went to put it in second and the clutch pedal never really rebounded from the depressed position. I had to pull it up with the top of my foot. Depressed it again, and again it stayed in the depressed position until I picked it up with my foot again. It sort of "popped" back up. From there, it seemed to work properly, although I think it feels a little bit "softer" than before (i.e. not as much resistance). I've read about firewall flex and I'll look into it this weekend. Possible air in system? If it makes any difference, this morning was one of the first cold mornings we've had.
Anyway, I'm at work now, and a bit nervous to drive it home. Any help/advice would be much appreciated!!
Thanks for the info, bigdaddy. I've got a few stupid questions (sort of a newb), but where is the slave cylinder located? Further, are there any tell-tale issues that I should be looking for in regards to air getting in the system? Also, could a low transmission fluid level be a possible reason for this? Is there a fluid resevoir near the slave cylinder?
Yes, you need a new slave cylinder. It usually doesn't give much warning before it craps out completely, so act quickly to prevent being stranded. The transmission has to come out to replace it, so if you need a new clutch or rear main seal now's the time to do it. If the slave is in marginal shape, the cold weather usually pushes it over the edge.
As a side note, I like to renew the clutch slave and master cylinder together because they wear about the same. Everytime I do one without the other, the other one fails within a month or so. Just my humble advice.
