i have 2005 cobalt ss/sc 5 speed, and i was pulling into my driveway and i pushed the clutch in and it didn't make any noises its just the pressure stayed at the floor so now i cant shift or engage the clutch. now i have been told it might be my slave cylinder or the clutch master cylinder everyone is saying its my master cylinder cause my reservoir is still holding fluid, and if it was the slave cylinder there wouldn't be any fluid in the reservoir it would be on the ground.

 

Well the brakes and clutch r on the same master so if that is bad your brakes should be having some issues but try and bleed the clutch and see if that helps cuz the slave aka throw out bearing is inside the transmission can't really check it without tearing the car apart good luck man

 

before it this issue every time i would back up the brakes wouldnt do a high pitch squeek it would do like a howl then i would stop if i hit the breaks after i let go of the brake it would do it again but it only did it in reverse

 

That maybe just that u need new pads in the back have u had any softness in the brake pedal is what I'm saying like u push it and it moves really easy

 

no not that i noticed

 

Then I don't think that the master is bad

 

is there somewhere i can go to figure out how to replace the slave cylinder

 

U have to pull the tranny out but do a search on replacing clutch and u should find something
