If your clutch pedal doesn't quite have the pressure it used to, or your
clutch fluid just looks old and dirty, it may be time to bleed and/or
replace the clutch fluid.
Items needed:
8mm open or box end wrench
Clear tube (1/4" ID)
One bottle DOT3/DOT4 brake fluid (doesn't have to be full)
A friend to press the clutch pedal for you
Locate the bleeder valve on the clutch slave cylinder.
Use your 8mm wrench to open the valve one full turn, don't remove it.
Stick your hose over the bleeder valve and have it drop off into a container.
Be sure to check the clutch fluid level before bleeding the system, you don't want to let it get below the MIN line.
Have your friend pump the clutch pedal to start removing the fluid.
Don't be con if they tell you the pedal went down to floor and won't
come back up on it's own, that's normal. They'll just have to wedge it
back up with their foot.
NOTE: When bleeding the system, make sure the cap is ON or you will just be sucking in air
Refill the clutch fluid as necessary to keep it above the MIN line.
Since the clutch fluid reservoir is very small you'll have to keep a
close eye on it.
I just had some extra ATE brake fluid left over from my brake fluid
change so I decided to just use it since it is a DOT3/DOT4 fluid. But
high performance fluids are not necessary for the clutch fluid so you
can just use regular cheap DOT3 or DOT4 fluid and it won't make a
difference.
When you see the fluid in the hose change completely from the old color
to the new color then you know the system has been flushed and is now
full of new clutch fluid. Have your friend do one l press of the clutch
pedal and tighten the bleeder valve once the pedal hits the floor. Since
you can't use a torque wrench on the bleeder valve, it's important to
note it does not need to be very tight so don't try overtightening it
and just snug it up with your wrench.
Pump the clutch pedal again and the pressure should return. And that's all, you're finished.
