Default Clutch pedal problem

I finished changing the brake master cylinder on my son's 1989 Hardbody and went to start the truck. The clutch pedal wasn't moving so I pressed hard on it and something let go and now the pedal is on the floor . I checked the area around the clutch master cylinder and don't see anything unusual like a rod sticking through it and no leaks. I'm not sure if it was something in the slave cylinder or not but thought maybe I could get some ideas here.

something blew. see if there is fluid under the truck. it probably blew the fluid line to the slave cylinder or the slave cylinder blew. check the fluid level in the clutch master cylinder. if its low, put some in there and move the pedal by hand a few times. then look for leaks.

it can also leak down the push rod and inside the cab.

Sounds like the clutch master took a dump. It's also possible that there is a problem with the pressure plate. Have you inspected the slave cylinder and the fork?

Im suspecting slave as Ive had them explode rather violently while driving. Id check the slave and see if the seals blew out. If it did there will be fluid under the truck and all over around the slave.

I finally got a chance to look at it after waiting out the 110 degree afternoons and monsoon storms and found that there is fluid all over around the slave cylinder, so it looks like I'm replacing at least that. If that works, it's going up for sale!

Replace its hose too. "Fun" to bleed, so be sure to bench-bleed the slave cylinder before installing.

If you haven't replaced the clutch master cylinder, it's likely time. Bench bleed as well.

Some of us replace these in pairs; I do on my '88 Mazda truck. My 1998 and 2004 Frontiers haven't needed these to be replaced yet (211K and 98K miles).

Ive done both slave and master without a bench bleed. It wasnt too bad but did need 2 people and took a littl time. Keep a sharp eye on the fluid in the resevoir as it is a tiny resevoir and runs out fast!
