My master cylinder went out a year ago (piston plate bolt popped it's cap) after only a few years of use. Replaced it (probably like 5k miles ago, I don't drive a lot). Then last month my clutch started making this noise:

I thought the plastic bushing in the clutch pedal was the culprit so I replaced that and greased it with high temp urea grease first, then switched to white lithium, but still the problem persists. I can feel the sound in the pedal and the master cylinder itself.

Anyone know what this is? Are these exedy cylinders somehow just garbage? Help please!

 

Following: I replaced my clutch a year and a half ago in my 3.5L, 6spd MT, 2011 Honda Accord EXL Coupe. The mechanic told me their must be something wrong with the parts I bought, because it's hard to get into gear. It is difficult and had a different shop, that specializes in transmission and clutch repair tell me the clutch is bad. That's one issue. But the other issue is the creaky sound you mentioned. The same transmission and clutch specialist told me it's inside the cabin, not the master nor slave cylinder. Despite greasing, it still creaks. So annoying. Not sure how to stop it.
