northbynorthwest Posted July 13, 2014 Share Posted July 13, 2014 Do I was driving down the highway yesterday, all of a sudden my clutch pedal was stuck to the floor, clutch engaged, truck in gear. Pulled over, pop the hood, hear a long slow hiss if some sort of pressure releasing. Clutch fluid level is slightly over filled so it's not actual leading any fluid. With the truck pulled over and turned off I rapidly pumped the pedal and felt it build up pressure again, was able to get out to shift normally for a little bit until it progressively loses pressure and I have to pump the pedal again. Long story short, my best guess is master cylinder is shot but want some second opinions, especially from anyone who has ever had similar problems. Opinions?

Terranovation Posted July 14, 2014 Share Posted July 14, 2014 The long slow hiss indicates a snake under there...lol jks It's most likely your clutch pad is almost gone and needs replacing. Link to comment Share on other sites More sharing options...
Kingman Posted July 14, 2014 Share Posted July 14, 2014 Sounds like bad master cylinder. Clutch disk wouldn't have an affect like this. Pressure in the system is what forces the pedal back to rest. If there's a leak or no pressure being built by the master cylinder, the pedal won't come back up. Link to comment Share on other sites More sharing options...
