Default Gravity Bleed the Clutch

Most of you probably already know this but I was pleasantly surprised to find it is very easy to "gravity bleed" the clutch without the help of another person. If you put a bleed tube and bottle on the clutch bleeder, open it about 1 turn with a 8mm wrench, then remove the clutch reservoir top it will bleed pretty quickly.

Before I did that I sucked out the old fluid from the reservoir using a big "eye dropper." I found a lot of black crap on the bottom of the reservoir so I put in some new fluid and sucked it up with the eye dropper until I got it all out. I then topped it off with fresh fluid and climbed under the car and gravity bled it.

The clutch has a small reservoir so don't let it get too low, it bleeds pretty fast.

I realize the clutch fluid doesn't take the abuse brake fluid does but don't go too long between clutch fluid flushes.

I gravity bleed all hydraulics in my car, brakes and clutch. Works great!

Yea, I've been gravity bleeding the brakes for quite some time but it didn't occur to me to try it on the clutch--I had the two-man concept stuck in my head.

As long as there is no air in the system to begin with.


And.. you don't really flush out all the old fluid in the slave.
Allthough that's not much - it depends on the thickness of the clutch disk.
If you want to replace ALL the fluid, you have to push the slave piston all the way in with the bleeder open.

This may also be the case with the brakes.
I don't think the new fluid will push out the old, certainly not all of it.
The piston in the brake caliper is a slave, just like piston in the clutch slave

That's a very good point. Hmmm.

I have the same question.
