How to Bleed a Hydraulic Clutch on a Motorcycle | Suzuki GSXR 1000 | Partzilla.com


Hello John Talley here with
Partzilla.com. Today i’m going to show you how to bleed the clutch system on
our 2007 Suzuki GSXR 1000. Pretty simple to do. I just need to grab a couple of
tools and I’ll show you how to get it done. This is going to be a very easy one
so it barely rates on the scale of a level one. As far as the tools you’re
gonna need? Really short list. Phillips screwdriver, 8 millimeter wrench, and just
a length of clear hose. Now as far as the parts that are going to be required for
us, it’s just gonna need some DOT4 brake fluid. Now if your particular project is
needing more than that, reference our drawings at Partzilla.com.
That way you can get everything that you need to get this little project
accomplished. So once you’ve got your parts and your tools together we can go
over there and I’ll show you how to do it. Alright starts by, let’s just go
ahead and remove this little side piece and get that reservoir cap open. If I
were you I would go ahead and lay down some type of cloth– something to you know,
protect your plastics. You do not want to get brake fluid on your body panels
because it will eat into that paint and or any decals you have. Alright how often
should you be doing this? Well they say to quote “replace your fluid every two
years,” and by the looks of it I don’t think this has ever been done because
that looks like some dark water nastiness that doesn’t need to be in
there at all. I mean new brake fluid has kind of a, I guess a gold tint to it, and
that is not a gold tint. Alright so not that tough, this is your slave cylinder
for the clutch. All you need is an 8 millimeter wrench and just a length of
hose. This is a 3/16, and just something to catch it in. We’re gonna be using some
DOT4 brake fluid. Want to keep the reservoir full, and what I’m doing is I
pulled out this upper plate and the diaphragm because we just want to put
the cap back on because it’ll actually spit fluid out at you, and we won’t have
the cap in place to keep that from happening.
So let’s start pushing out some of this nastiness. Go ahead and pull your clutch
in, open up the valve, and then it’ll start to push it out. Alright hold it,
open the valve, closed. Just like that. Alright as you’re doing this you want to
check it about every three or four times because it’s going to be drawing fluid
through the reservoir and you do not want it to run all the way out and
introduce air into the system. Pull in, open the valve, close, and repeat.
So we’re just going to keep doing this over and over again till we get new
fluid pushed all the way down to the slave cylinder. It’s gonna take a little
while, but it’ll be worth it. But the reason you want to do this is that brake
fluid is inherently what they call hydroscopic. It actually attracts water.
So this is an actually an open system that lets air get to it, and hence you’ve
also got water in the air so it can get in, it will get into the fluid. So it’s
important that you flush that out because you don’t want water in your
system for a couple of reasons, especially on the brakes more than
though on the clutch, is it has a lower boiling point compared to the fluid. The
other thing is if you’ve got water inside the system it’s going to break
down your seals. That’s going to start you know, breaking down the actual
pistons and components that are both in the the master cylinder as well as the
slave cylinder. So it’s important that you flush out and get in new fluid
that’s fresh. How many times you’re going to have to refill the reservoir? It’s a
little bit of a guess on my part but I’m figuring at least 10. Well that’s what
I’m gonna do. Plus you’ll be able to tell the the
fluid actually getting pumped out it’s gonna be a whole lot more clear than
when we started. Alright guys that’s that’s about ten
times the fluid’s starting to look clear coming out down at the slave cylinder.
Now we want to set our level and what we’re going for
this is upper mark right here. That’s your upper,
and this of course your lower. So I’m just going to fill it up to that level. That’s it.
Now you can take your little plastic diaphragm and that nylon piece up top,
get your cap back on. Now you just want to make sure any that was spilled
you go ahead and get off. Get this piece back on, holds that cap in place. Now make
sure that valve is shut all the way off, take off your hose, put your dust cap
back on– back on the slave cylinder. Well alright guys, that pretty much wraps
up this simple project. Well listen, no matter what parts you need we have it at
Partzilla.com, so why don’t you give us a call and we can get you taken care of. If
you have any questions or comments, leave them in the section below and I’ll do my
best to answer them. We just want to say thank you for all that you do with

  1. I always enjoy your videos. Not being critical, but here is a variation on your technique that I have found useful.

    I prefer to leave the cap off so I can see the fluid level. I have found that placing a clean razor blade into the reservoir will block the spurts. I also remove most of the old fluid from the reservoir with a turkey baster before starting. This will save much time as you are pushing fresh fluid through the lines immediately and not just slowly diluting the old fluid in the reservoir. Usually one or two fills of the reservoir will get clean fluid to the bleed valve.

  2. Hey John I have a quick question my raptor 700r 2010 won’t start all the lights turn on but once I press the button so it Can turn on it does 2 click noises n it won’t turn on I checked the fuses but everythin is good?

  3. Can you please make a video on how to remove the stator on a trx 250ex. I cant seem to find a video anywhere on how to replace a stator for a trx 250ex

  4. Did as shown but notice gear would not release while pulling in the clutch handle. thought i had air into system but not, using dot 4 what im doing wrong?

  5. to save time, use a syringe of some sort, to suck out all that old crappy brake fluid in the reservoir, fill the reservoir with new fluid and you'll save some time on bleeding it.

  6. I have a 2005 gsxr 600 I dont have a clutch reservoir , but I do see the brake fluid reservoir.. Same thing?

  7. Yo guys i got a question for my 2007 cbr1000rr i just brought it (its got hydraulic clutch). My friction point on my cbr is soon as u pull the clutch and goes to 1st my bike starts engaging 🙁 would u guys be able to help me what is the main cause of that?? Pleease 🙁

  8. Am I able to use a vacuum bleeder instead of doing the pump and hold method? Just for ease and speed.

  9. I have an 08 GSXR 1000 (essentially same bike). My clutch started not to have a lot of pressure. When I cranked it in gear, it would move as is it wanted to crank and pull off. It was hard to shift up and especially downI noticed that after riding a few miles, the issue would go away after the bike warmed up. I pulled up your vid to bleed it and now I have NO pressure. I’m guessing the slave cylinder is bad? I changed the chain and sprocket a few month ago and had to bleed the clutch then. Any input would help.

  10. Hi! I was injured my left hand working, and I lose power and movement. This kind of hidraulic clutch is very soft for move the clunch of my cbf 600?
    Thank you!!

  11. I have a 86 fazer fzx700. My clutch lever is real sloppy. And seems to grab about 1/2 inch before touching the grip. Can I adjust it?

  12. I replaced the front sprocket on my 1000. But took that bolt ( hydraulic bolt with hole in it) off the the sprocket cover to access the sprocket now I can’t neutralize my transmission. I have tension on clutch but no neutral when I pull clutch in. HELP PLEASE!

  13. Phillips screwdriver on a metric bike? Only if the tip is ground flatter. Get JIS screwdrivers instead! Phillips drivers on JIS screws = stripped.

  14. I need help getting pressure back into my clutch it was fine then I had nun at all cleaned the slave cylerder and bleed the clutch and still no pressure what do i do
