Loose clutch petal

What does your petal look like?

Like this?

Pedal stiffness is dictated primarily by the pressure plate fingers. That is after all what you're pressing against to release the clutch. I suppose it's possible for the spring tension to weaken on these fingers and pedal pressure to change. A fail[ing] csc will typically have a fluctuating grab point, or even all the way at the floor and dead pedal for majority of its travel.

Changing clutch fluid is very easy. Just did it a few days ago on mine. You'll need some apparatus to remove the old fluid from the reservoir (but not completely), then either gravity bleed or have a helper pump the pedal slowly then hold while you open and close the bleeder screw at the trans. I did a combination of gravity bleeding to flush new fluid through the system, then a helper for good measure.

Post a pic of your clutch fluid reservoir with the cover removed.

How long does the gravity bleed take? Do you just open the bleed bolt and let the fluid flow out?

Yes, that is what a gravity bleed is. How long it takes varies with how old the fluid is. Gravity bleeding is usually not quick but it does work. Make sure that you monitor the reservoir and don't let it run out. It doesn't hold very much fluid so it will need watching.

I myself, use a vacuum bleeder. It works and has been working for the past 15 years. https://www.griotsgarage.com/product...fType=&from=fn

This tool can be used for lots of car work.

According to the FSM, it says...

NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of vacuum assist or power
bleeder will not purge all the air from the system.
