who's that for wall maybe yes you're
gonna have a couple bleeder screws on
top right here right here but to bleed
those you're gonna have to open up the
internal bleeders and the internal
bleeders are gonna be down here on the
side also these little pistons right
here the high-pressure pistons you're
gonna have to push in each of these here
to get it to bleed correctly and there
is a special tool dude made for that
I'll show you what I built and you can
try to build something close to it it's
really simple and how to how to build it
but I'll go ahead and we'll go ahead and
start with that tool tool I built for it
like I said it's very simple there's not
much to it at all this piece right here
is what you want around this ring to sit
inside that ring that is one inch inside
there so I just took a piece of pipe
measure to - when he decided to get my
one inch center cut it then took a
ticket angle grinder and cut it all out
right here does not have to be squared
off like this if you have a one inch
drill bit that'll work - and I just took
them love the nut on it right here so
basically when you have this thing
together on there you just tighten it up
just like so it'll push in that bleeder
so if you don't have a welder to weld
down bolt on to there you could actually
put the bolt here on the inside and that
will work as well this is inch and a
quarter pipe so it gives it plenty of
room if you put a nut on the inside that
would work as well that wouldn't even
have to be welded to do it like that'll
just press against itself I'll show you
how it works all right so here it is so
basically this tool is going to slide
right over this ring right here just
like so it said something I can't go
into where it's locked in right there so
basically from that point all you're
gonna do is is screw it in the screwed
in right till it's touching it just like
so it's snug it up just a little bit and
it's gonna be I've got 1/2 inch bolts
there's gonna be a three quarter inch
wrench just do a little snug on it and
it'll hold it in place that's all you're
gonna need right there you're gonna do
that to both sides
just leave those in place all right now
you're going to do the internal bleeding
screws it's going to be this screw right
here there's a 10 millimeter all right
crack that loose about a quarter to half
a turn just so it can loosen up the
internal bleed or just a little bit all
right
there's will be one on that side 180
degrees there's gonna be another one
right here this will be 10 millimeters
so crack both of those loose all right
now that you've cracked both of them
loose and you have your high-pressure
pieces on here to keep your
high-pressure Sun always locked in then
you're gonna go down to your regular
bleeder screws like our on any car okay
there's gonna be eight millimeter this
is gonna be the front this is gonna be
the back as it sits on the car that's
what you want to do have the person push
the pedal down today start feeling just
a tad bit of pedal it's probably going
to be about 25% of the way down just
they feel just a little bit of pedal
then you want to stop
have them hold break it loose and have
them push all the way to the floor
go to squirt fluid out of there as soon
as they're done tell them to keep on
holding it so you tighten that back up
once that is tightened back up they can
lift off one time let it set for a
second let it pull the fluid through
check make sure your fluids not low and
then start over again I hope that helps
you out on how to bleed those I know
they're a pain to bleed some of them say
that you have to go to the manufacturer
and have them put it on a scanner this
this requires obd one GM tech one to go
ahead and pulsate the motor on it to
push the air out of it another way is if
you go on a gravel road dirt road or mud
or something like that hit your brakes
let the ABS activate it'll push the air
through the system and you'll probably
have to bleed your brakes one more time
but this is another way that you could
do it on the truck if they feel kind of
spongy you can go ahead and push some of
that out and see what that fluid looks
like it's not hard to do as long as you
have those pieces to do it with and like
I said they're not that not that big a
deal to build you can buy the pieces I
think they're 25 or $30 apiece so it
would be about 60 70 bucks something
like that for the set I just had some
scrap metal laying around in a bin and
just built this it was super effective
and it worked
this system is not on the truck right
now because it was actually bad once I
bled everything out and went through it
it was actually a bad I couldn't get the
motor to activate in it so I put another
one on it but I hope that helps you out
on how to bleed the system out if you
have any questions that I can help you
