hey everyone GarageKing here and I'm going to show you how to change the
brake fluid and bleed your brakes on your motorcycle, this one's a GSXR 750 so
let's get to it, and on the reservoir which we got to keep topped up is
located in there, there's a bolt there you can kind of see it and if I come
around the corner there you can sort of have to see it there you go it's right
in there so how the heck do we fill it up? Well
what we're gonna do, is we are going to take that bolt out and actually take the
reservoir out and just kind of hold it to the side hold it to the side right
here or zip tie it or something like that
okay and there's a bolt 8mm
so now our reservoir should come free we just gotta wiggle it out there we go
and there's our reservoir and it's free so now what we can do is we're just
gonna zip tie it so when we bleed it we can make sure we change the fluid property
and it is dot 4 fluid okay, and you can just see a zip tied it there, actually a
zip tie to just to the battery terminal there just to hold it relatively
straight now the one thing you got to make sure when you do this keep a rag
handy because if you spill any fluid make sure you wipe it off right away
because obviously the brake fluids gonna eat your paint up okay so we got our
little brake bleeding wrench, it is a 8mm that goes on the screw, I pulled off
the little rubber cap we can just put that on top of the wheel for now we're
gonna have our wrench just like this, and then once we loosen up we can either do
it two ways, we can gravity bleed it which means it's just gonna keep coming out
and falling out until it until it comes out clean or we can manually suck it out.
So we're gonna try gravity bleeding at first and see, but what I want to do is I
just want to put something underneath just in case. We're just gonna open
it up there we go hmm let's see how it drips down there we go and you can see
it's uh it's coming out so now if we undo the cap quicker because we're gonna
let air into the system so I'm going to undo the cap
so we'll just let a gravity bleed just like that and then once it's clean we'll
just keep putting a little bit more fluid in this one is quite a small
reservoir the reservoir is open so you can see there's the fluid there and it's
gonna be getting near so I'm gonna have to add some okay another way to leave
the system if you have a good helper. I'm actually, believe it or not doing it
myself, I just can't get all the angles at the same time of the camera is I'm
filling up the fluid and what I'm doing is I'm cracking it free pushing down on
the brake pedal there you go tighten it up, and foot off the brake pedal, loosen
it up, push down, tighten it up, foot off the brake pedal, and I'm just kind of
pumping it like this and it's actually working pretty quick and you can see the
fluids already quite clear coming out now a nice clean fluid like that I just
got to put some more fluid in and they done to your reservoir yeah okay so we
finished the rear nice and good I'm just gonna let it dry up put some brake clean
on there wiped it all down with a rag everything's nice and dry, do not forget
to put your cap back on so we got our nice clean upper cap so we're gonna
put that back on there you go our cap is back on so, that's so good. Now moving to
the front we can see here's the reservoir so we're just gonna do this
Phillips head screw right there now if we look down to how the brake lines are
run you know possibly there's actually two lines on this caliper if you want to
call this the passenger side caliper and then there's one driver's side caliper
if you want to call it this, so what happens is the fluid all runs to the to
the other side first then it comes to this one so if we drain this one we'll
get it all clear and what we can do is we can crack the other one just to just
to see now the bleeder for this is right it's right in here actually there you go
you can see it it's right there now the problem is the way I have it on
the stand it's really hard to get to the bleeder, so what I'm gonna have to do is
just move my stand a little bit to tilt the wheel just to turn it a bit and then
I'll be able to get to it okay so I've turned the wheel so I'm
gonna do is I'm gonna undo this there we go take the rubber piece off right there
I can get to it and then the wheel is turned all the way that's all we can get
to so I don't know why Suzuki didn't put the bleeders on the outside? Maybe air
resistance or something like that? I don't know, so what we're gonna do is
we're gonna undo this now with these I think I don't want to drip it everywhere
so I'm gonna get a tube and we're gonna install a tube on these ones to do the
front it's a rigged up a little thing here so it's got a suction piece so
that's gonna go on to the back of the on to the back of the caliper right there
and then as soon as I turn on the air just like this we'll give it a little
bit of a little bit of air this way
I just like that, so that's how we're gonna do the Front's
okay and you can see I haven't even applied air yet I just loosen the
caliper and you can see there's actually brake fluid coming out of it right
there so it actually wants to come up, but before we apply the air we
have to make sure that we can put new fluid in the same time its sucking it up
cuz we don't to get an air in there so what we're gonna do is we got our
reservoir right here a Philips screw right here so we're just gonna undo the
Philips screw just like so and now we can undo the reservoir, make sure to use dot 4
fluid its first piece off and there we got that there we go
second piece off and you can actually see the color of the fluid, quite yellow
and you'll see once it's done it's gonna be nice and clear
okay so we've topped off the reservoir, see the reservoir so now what I'm gonna
do is just apply a little bit of air here, not much but just a little bit here
you can see slowly
again okay and we are all done you can see the fluid is nice and clean it was
quite yellow before so now we're just gonna tighten up our bolt here just like
so and she's all done we had good brakes we gave a little bit
of wipe there we did have a little bit of mess there you can see a little bit
of a mess, I shot it with a little bit of brake clean just to clean it up because
I don't want any brake fluid sitting there and that's it
