After having driven my Alfa Romeo 147 for over a year, the clutch pedal began squeaking with every depress and release of the pedal, and after a quick check online, I realised that this was actually a common problem faced by many Alfa Romeo owners, a problem not just confined to the 147 and certainly not to Alfa Romeo. The noise is, to describe in one word, annoying. It is a thorn to an otherwise smooth, quiet and creakless drive.
It took me some trial and error to figure this one out, and I eventually traced the problem to the clutch master cylinder. The solution is a rather easy one, but the correct lubricant is especially important. Do not use water-dispersion lubricants such as WD-40, STP AP-75 or similar as these will not work in the long term. They may stop the squeaking only temporarily for a day or two at most. The most effective and appropriate lubricant to use to resolve this is white lithium grease. There are many commercially available off-shelf products; see the links at the bottom of this article for a number of recommended brands.
Getting Down to Greasy Work
See the following photos to find the source of clutch pedal squeaks and resolve them permanently. Here’s how to fix a squeaky clutch pedal:
The effect of the white lithium grease should last for a good year at least, maybe two. Whenever it wears off, you know you can always repeat the procedure above to have a squeak-free clutch pedal action again. A little disclaimer – my mechanic had advised that it isn’t a fantastic idea to squirt lubricant into the master cylinder, but I have done so a number of times over the last three years with no adverse effects or damage. In any case, proceed with the above procedure at your own risk.
UPDATE IN 2018: It has been 5 years since the last time the master cylinder was greased and the squeaky clutch pedal problem never came back.
