My truck is 21 years old, both of those items are original and I am really thinking that they need replacement BAD!!!!! I have them both in the garage and have spent a little time studying the job before diving in.
One impression that I have is that it looks like this would be real easy if you just remove the master cylinder from the firewall, remove the slave cylinder from below (it is external!), fish the whole thing out of the truck and work on it in the clear and open driveway. Once done, lower it back under the hood and bolt both back in place. Does that seem pretty accurate?

 

I don't see why that wouldn't work. Sounds like a good plan to me.

 

Just to have a reference....
I had already bought the parts (both master cylinder and slave cylinder) and asked a shop what they would charge to put them on. The owner came back with $300 labor only. Any opinions on that?

Looking at the job for myself, I was figuring on removing the bench seat ('cause I'm big, it isn't but 4 bolts, and it makes time under the dash a LOT more comfortable), then unbolting both pieces and removing the whole thing as an assembly. I just don't see that much labor but then, he's got to cover his time I guess. (P.S. he has already told me that, since I am supplying the parts, there will be no warranty on the labor. That means "standing behind his work" doesn't count this time!)

 

wow $300 for labor only. I'm thinking less than an hour to change over. Two nuts hold the master to the firewall, the slave just clips onto the trans. Then Bleed the system.

 

Thats what I'm thinking.....

Do it myself and ask "mama" for the $300 !

 

to do the master and slave cylinder change, all you need to do is unbolt it, like said previously. one thing though. when bleeding it, you should do it while out of the vehicle. if you do it when its installed in the vehicle, for some reason it will always keep a bubble in the slave cylinder. the much easier way is to hold it vertical and have a buddy help turn the bleed screw. make sure all air is out and seal the system. then just route it like you took it out and you should be in business. hope this helps

 

Yes sir, that is pretty much what I had in mind. I figure that it's a lot easier to do sitting out in the open than squished up under the bottom of the truck....
