alright guys so I I have a little
specialized thumb Trumper and it's got
the hayes 9 hydraulic brakes and this
thing was sitting for maybe 2 or 3 years
I haven't hadn't ridden my bike I've
just been busy you know with work
working all day non-stop and work owns
me have my own business but I love this
bike it's a it was an awesome bike my me
stole this I took it out from the from
the storage actually the stone room you
see it's got a lot of dust on there
right I mean it's just been sitting
there spiderwebs
all around so there's no brakes no
hydraulics something kind of great so I
never bled the brakes on this thing so I
had to do a whole bunch of YouTube
watching a bunch of YouTube videos I saw
the one from Hayes themselves I bought a
Hayes kit talking about inverting the
reservoir upside down so it's at the
high point taking the calipers off in
between kit with the two syringes and
whatnot
I was like that's a lot of work man just
for that so I saw another video where
the guy was just just took a bottle of
brake fluid and then he basically took a
little cap off will be here you pigs
just pull it off and then he just kind
of put a little bit of fluid in that
little bass right there he kind of
played around to leave her a little bit
and let the air come out so what I did
was I did get the haze kit I was
thinking like well let me see this thing
works because if it works for him just
puttin just puttin a little bit of fluid
on here and pumping this a little bit
until the air comes out why can't I just
go ahead and put the syringe directly in
here and not even worry about the about
the dual syringes you know just put just
fill it up and then
take the syringe out take this friends
out with it and then do what he
suggested which is a great idea and the
bubbles will come out put the syringe
back in so I'm gonna show you what
happened that's a really quick and easy
solution all you need is that one
syringe and I'm gonna put some pause I'm
gonna do the same thing every fix this
side this that's done okay and just took
like three minutes to do basically so
you put some pause I'm gonna follow up
with the setting up this break okay
we're gonna turn that upside down I'm
not gonna take the calipers off I'm not
going to unclip them take them out okay
I'm here with two syringes and playing
around with that I'm just gonna
basically show you what I did and it
works okay so I got I loosened the bolts
opaline wrenches over here I turned it
upside down okay and now got that little
plastic cap one another thing I made me
think about this was this plastic cap
it's not even screwed in it's not
airtight it's just look just a plug the
plastic plug I'm like well this thing
realized in hydraulics and shouldn't
that be pretty tight and the brakes
working perfectly without without this
being screwed in without he kind of
steal anything like that's just it just
plugs in see that so we're gonna pause
again I'll show you what I did alright
so I used the syringe I did use the
adapter put this together over here so
this nipple can go into the into the
reservoir and I took the air out of
course you just pump it up let the air
pop out come out and then until there's
no air in the syringe and then you stick
the syringe into the into the oh you
push it in tight seal because the rubber
so um you notice I'm gonna pump this
really slow until I get know until I get
some resistance and then when I let go
you're gonna see air coming up yeah
I push it down quite a bit actually say
that about two millimeters like though
and look at that it sucks all the air
out see that all the air came out that's
all you got to do so
take the syringe out so I'm gonna take
this out and I really should I forgot to
put the the napkins around underneath
here to prevent it from dripping onto
the bike but it's nothing underneath
there but anyway pull this out okay okay
nothing's coming out it's a lot of air
turn it upside down
okay I'm gonna again napkin I'm gonna
squeeze this air out again until there's
no air in there I'm not gonna do the
same thing repeat until there's no air
coming out
okay so push all the air out again
there's no air might be a little bit on
the tip no matter now this is just where
the haze nine I don't know about any
newer hydraulic brakes but this is the
haze nine because like I said it just
has a plastic cap on it that just pushes
in doesn't even screw in push that in
there again okay and you notice not as
much ear comes out anymore and I should
have shown you guys there was this lever
was going all the way to the there was
there's absolutely no hydraulics left
this was just no brakes whatsoever okay
so now pump this again okay goes in a
little bit more before about one ounce I
think and you see it's sucking at 1 mili
milliliter sorry about that
push it in again put pressure on it
push it down put pressure on it and then
let go and look at that sucks all the
air out the syringe sucks the air out so
what I did now I just kept it in here
until you see the still air coming out I
kept in air for a little bit a little
bit you know like 15 seconds or so
okay and more air came out okay pause
again I think this will be the last one
but I'm gonna try one more time just be
sure I just real quick so I'll show you
how you get the air out so you want the
syringe to be upside down so there are
pockets on top like that okay air
pockets on top and then just push the
syringe up until the air is completely
out onto the earth okay so last one it's
the third one um I don't think I need to
actually put any more fluid in there but
I'm gonna try it again put that in to
[Music]
push it down against the rubber gasket
with a rubber sleeve okay and then again
you're gonna push slowly until look it's
not hardly going down maybe half a
milliliter that's it so here comes out
still some more air see that what a bit
of air came out now you keep it upside
down the air stays on top right so
here's on top over here so you're
pumping you still there's still no here
in the bottom so you can still push
again now watch when I take this out
what's gonna come out of that hole okay
so then take that out fluid comes out I
do put the napkin back in so put the
syringe down put the plastic cap put the
plastic cap back in
okay that's it
wipe it okay and before the bike was
moving I got brakes it's stopping my
clips up so I'm done okay so real easy
you don't need to use two syringes you
just need to use one so it's a
combination of the Hayes video what they
say you need to do taking off the
calipers and all that combination at
that other video which I thought was
great
that's all I was going to do just just
putting a little bit of getting a capful
and putting a little bit of great fluid
in this little the cavity over here and
then pumping the brake something to let
it come in let the air come out it's
basically just use the syringe and it's
done so basically three goes at it and
maybe just took about five minutes and
it's done
