Clutch Master Cylinder (Video)

Hi all

I have problems disengaging the clutch and getting into gear (particularly first and reverse) since the recent cold snap.

The issues is more present the colder it is.

I've replaced the clutch fluid to rule out contaminated fluid.

What I should have done first is look at the master cylinder ! The rubber which the clutch pedal push rod goes into is partially covered in black liquid. It also creakes (but always has)

I decided to take a video which you can find here:

You can hear the creaking but I also noticed that the push rod does not look to fit correctly toward the end of its travel.

I think I need a new master cylinder but am not sure about the push rod side of it ?

Any idea how much a garage will charge for changing the clutch master ?

Thank you in advance.

yeh looks like its been leaking a bit. I'd top up your fluid, press the clutch and see what comes out.

Usually slave brakes before master cylinder.

The creaking is not the master cylinder, its the lateral scraping movement between where the cylinder eyelet connects to the clutch pedal. You need a washer to stop the movement! there is a thread with diagrams, search 'creaky clutch' or something similar.

I had a new master cylinder fitted last year because of creaking (can't remember price, sorry). I noticed the same type of movement on the new cylinder as you have shown here (maybe a little less pronounced in my case). The movement of the piston does not seem to be linear along the length of the master cylinder. It was an Alfa part fitted by Alfa specialist. I wondered if this could be the reason they tend to creak and fail prematurely. Never noticed this on other cars but then none of the other cars I have driven have ever had this type of problem. 12,000 miles later and the clutch pedal has been creaking for about 4k miles. No leaks from the master cylinder.

Thanks for the feedback.

Looks like a new master it is ! although the car has been a lot better today because the weather is not too cold and because I changed the fluid it has developed a click when the clutch pedal reaches the top, you can feel it on the bottom of your foot when releasing. After reading up on the issue it also seems the master is at fault.

If anyone knows what the going rate is that info would be much appreciated.
