dirty_mech Posted September 17, 2021 Share Posted September 17, 2021 So my clutch pedal has started to click, usually when depressed but it can sometimes happen when released as well. It can happen pretty much anywhere in the pedal stroke. It is definitely coming from the footwell area. I've tried to lubricate all the moving parts, to no avail. The click can be felt through the clutch pedal when it happens, indicating some sort of mechanical issue with the pedal mechanism itself. I searched around for answers and suggestions in various places have ranged from an unseated spring to a worn connector pin between the master cylinder and pedal. Couldn't find anything about it on this forum. Has anyone else encountered this problem, or found a solution? Link to comment Share on other sites More sharing options...
dirty_mech Posted September 17, 2021 Author Share Posted September 17, 2021 (edited) Just investigated the issue further, and it appears to have been my aftermarket Duralast clutch master cylinder. Sprayed some lithium grease inside the protective boot and the noise changed completely. The click is 95% gone but there is a bit of squeaking now (probably from the aerosol solvent). Total garbage part despite having a "lifetime warranty". Got it because one or both of the cylinders went bad after a clutch replacement job and I was in a tight spot without a working vehicle or many options. I'll probably end up replacing it if it continues just because it's so damn annoying. Pierced a small hole in that boot so the solvent can dissipate overnight and I'll see how it behaves in the morning.

The lithium grease spray inside the boot of the clutch master cylinder did the trick. No more clicking, and the squeaking subsided with the evaporation of the spray solvent. I've seen this issue posted on other Subaru forums and for other types of vehicles. Just a heads up that this appears to be the fix. I'd recommend using a hooked mini pick to temporarily stick a foreign object like a chopstick between the cylinder boot and shaft to allow a gap so the solvent can evaporate overnight. I only pierced the boot because I got frustrated laying upside down in the footwell for so long. Edited September 18, 2021 by dirty_mech 1 Link to comment Share on other sites More sharing options...
