Clutch dragging

[radroach]

Hi, recently I started noticing noises, like a slight wooo sound when revving slightly. I pulled into an enclosed area and could hear a slight dragging sound, so I can definitely tell I've got some kind of issue. I had the engagement point adjusted years ago and no issues til now, so I'm wondering what it might be. Should I try and bleed the master cylinder?

Wouldn't hurt to bleed the clutch system and re-adjust the clutch.

Might fix it.

Only with the clutch depressed? Could be throwout or pilot bearing. Both of mine were pretty beat when I changed my clutch, lots of play in the throwout and the pilot was starting to get crunchy.

Did bleeding help? I'll guess no.

Can you compare the sound to something else? Sandpaper? Coffee grinder?

Is the pedal pushed in all the way?

Does it start as soon as you begin to push the pedal?

Does the pedal feel like you're dragging your shoe across gravel?

It sounds like sandpaper. Was only able to hear it in an enclosed space. Note this was also on a hot morning with the car started cold. After driving a bit, the issue seemed to go away. I guess the hydraulic clutch gets settled into a better operating condition after a bit of driving.

The issue hasn't come back since that morning when I made the post, but im still going to get the clutch bled out by a shop soon enough.

Absolutely I've had issues with a noisy bearing, but mainly only when I'm driving too hard in hot conditions. Luckily I've ordered a whole new OEM clutch.

[It's not the hydraulics]
While it's never a bad thing to bleed any hydraulic system, it won't make any difference here. Not trying to bum you out. Just setting expectations. Air in the hydraulic system only shortens the effective pedal throw. Some is taken up compressing the air bubble.

The end result is difficulty or inability to engage any gear from a standstill with the engine running. This occurs because the clutch never fully disengages. If you let go and immediately pump down again, you can retrieve little throw. More hydraulic fluid is pumped in before the bubble has a chance to fully expand.

The same pumping thing goes for brakes.

Air will not magically appear in the system. Consider that when you bleed it. If you had/heard no bubbles, that's it. Be done with it.

While under the hood, pull the clutch fork forward and watch the fluid rise in the reservoir. That's the automatic adjustment. When the pedal is fully released, a valve opens allowing fluid to flow backward into the reservoir. The first part of the pedal throw is used to close that valve.

If the sandpaper sound was real and related to the clutch, it must be the throw-out bearing. Keep listening for it. If it's the bearing, it will only get worse.
