1998 Pontiac Sunfire GT 2.4L Master Cylinder Problem

[jordanlt1]

Hi all I own a 1998 Pontiac Sunfire GT 2.4L engine with a 5 speed standard transmission.

* I have problems i believe with my master cylinder for my clutch as it will be hard to shift but if i bleed my clutch it will be perfect. When it starts acting up i can pump my clutch and it will make the shift easier for the mean time until i get a chance to bleed it.

* I believe its a symptom of my master cylinder maybe internally leaking? I dont notice a leak to my clutch reservoir when it starts getting hard to shift so which makes me believe it may be internal.

* My question is:

- Would this be a sign of a master cylinder failing?
- If so how would i go about replacing it? Would i have to pull the transmission?
- If not what would/could it be and how would i go about fixing it?

* Thanks for any help its starting to get annoying!

From a diagram I see the clutch master cylinder is mounted to the firewall so I dont see why you would have to remove the transmission. The other component to the system is the slave cylinder. You see no external leak on either part?

Im looking and i dont visually see a leak coming from the master or slave cylinder but im not 100% sure if im looking at the right spot, but again i never have to add fluid to my reservoir so makes me think that its not leaking.

is the line between the master and slave made of rubber? If it is clamp it shut and step on the clutch pedal. Keep pressure on it for a few minutes. If the pedal starts to drop the master cylinder would appear to have an internal leak. If it doesnt drop it would point to the slave cylinder. You could also just replace both of them.
