Hi all I'm back in have a 93 toyota pickup 4wd and recently my clutch has been spongy so we took a look and thought it was my master cylinder we replaced it bled clutch worked great. But if I leave my truck sitting for more than a day or two since it isn't a daily driven vehicle the clutch is to the floor again. Could I just need to replace my whole kit could it be leaking or another problem all together. Any info is greatly appreciated.

 

sounds like a blown slave cylinder

 

Is any fluid loss noticed ??

Pull the boot back on the slave cylinder and see if it is full of fluid

Change one most often change both

Then most of the poor quality ones might only last a few hours
