Now, now. I know. Synchronizers are made of butter in the C60 and etc. I'm sure that at least one of these grinds is a synchro and I'm pretty sure it's the 3rd-4th gear synchro.

My problem is that when I've been driving (accelerating, braking, shifting, cornering) for a period of time that I'm too distracted to keep track of, my clutch feels like it isn't pushing as far as it needs to. My idea is that since the brake and clutch cylinders are the same system that maybe the fluid is overheating or there are bubbles in the lines or something like that, I'm probably just gonna flush and refill the system.

Would that make sense? Is it accurate that changing the brake fluid to a higher quality type or bleeding it properly might fix any of these problems I'm having?

It is the original clutch, as soon as I'm done fixing the timing chain cover in a little bit I'm going to start saving again to try and buy a new clutch. I know that may be an important part.
