Got in my truck today to come home from work and all was good until i stopped at a light. When I started off again the clutch began to disengage sooner than normal in the stroke. Then it felt like there was, for lack of a better term, a hump in the stroke. immediately after that hump it engaged again. Then it disengaged like normal from there on out. It happened all the way home but only when the clutch was engaged for about 30 second or more. any shorter and it was smooth and normal. Anyone have any ideas?

I should mention it is the m5od and that I replaced the entire clutch system about a year ago.

Thanks for any input.

 

Is the pedal softer to push or about the same? When you say hump, meaning you have 1 slight hard spot in the stroke? I would have a look at the reservoir level to be sure.

 

Pedal feels normal on its way to the floor. On its way back it immediately began disengaging and slipping the clutch, much sooner than normal and then hit a rough spot almost like its stuck. Then it gets over that hump reengages the clutch and then gradually disengages like it should. All i can think is air bubble but ive never had an air bubble do this.

 

It does kind of sound like an air bubble, but I would double check the fluid level too and see if thats up to par
