My clutch pedal was making a loud clicking/creaking noise for months, I was convinced it would give in at any sec :shock:, and was anticipating being stranded whenever I drove for more than 10m. I made up a pedal support bracket myself which helped a bit, but the noise was still there.
I also had fluid leaking into the footwell from around the master cylinder seal.
When I eventually got round to replacing the master cylinder I removed the dash to check the pedal mounting bracket, turns out it was OK.
All I'm saying is in my case the noise turned out to be the master cylinder, so it might be worth a check.
