welcome to ceramic Nicole communication
today we will be guiding you through the
bleed procedure but avid elixir breaks
let's get started by taking a look at
the materials and tools you will need in
order to complete this service procedure
safety glasses and nitrile gloves an
avid bleed kit and a t10 Torx for
cleanup you'll need water or isopropyl
alcohol and a lint free rag when
bleeding breaks you may notice this
coloration of the old fluid as it exits
the system into the syringe at the lever
if the fluid is severely discolored this
indicates that the fluid is very old
in this case bleeding the system twice
in order to completely remove the old
fluid is recommended before you get
started make sure that the bike is
oriented so that the brake lever is
higher than the brake caliper fill one
syringe 1/2 full of avid brake fluid and
the other syringe 1/4 full hold each
syringe with the tip pointed up and tap
the side of the syringe with your finger
to bring any air bubbles to the top
place a towel around the tip and slowly
push the air bubbles out of the syringe
close each hose clamp and pull on the
plunger bubbles will appear to form an
enlarged continue to pull on the plunger
and lightly tap the syringe to release
the bubbles sticking to the sides and
the bottom so that they can rise to the
top of the fluid when the bubbles stop
forming and have all risen to the top
release the plunger open the clamp and
carefully push the air out repeat this
process several times now that the
syringes are ready remove the wheel from
the bike
remove the brake pads from the caliper
and insert the appropriate bleed block
this will help your batch system
overfill and keep brake fluid from
contaminating your brake pads use a t10
Torx to remove the caliper bleed port
screw from the banjo bolt or caliper
body make sure the fluid and the 1/2
full syringe is pushed all the way to
the tip then thread it into the caliper
bleed port for models with pad contact
adjust and a fixed bleed port screw
rotate the adjuster in the direction
opposite the arrow until it stops for
models with pad contact adjust and a
weave port screw located on the pad
contact adjuster rotate the adjuster in
the direction opposite the arrow until
it stops then rotate the adjuster back
just enough to place the bleed screw at
its highest point use a t10 Torx to
remove the lever bleed port screw make
sure the fluid and the other syringe is
pushed all the way to the tip with no
air gap then thread it into the lever
bleed port a small amount of brake fluid
may drip from the bleep port screw this
is normal pull both syringes upright
gently push on the caliper syringe
plunger to move fluid from the caliper
syringe through the system and into the
lever syringe until the lever syringe is
increased to 1/2 full and the caliber
syringe is decreased 1/4 full you should
also see air bubbles fill the lever
syringe
close the clamp on the lever syringe
pull the brake lever to the handlebar
and fasten it with a toe strap or rubber
bands pull out on a caliper syringe
plunger to create a vacuum then gently
push Ana on the plunger to pressurize
the system repeat this procedure several
times until large bubbles stop coming
out of the caliper be careful not to
pull out too hard on the plunger or
you'll pull air past the plunger seal
once the large bubbles at the caliper
have stopped remove the toe strap or
rubber bands from the brake lever but
keep the lever pulled in with your
finger while keeping pressure on the
brake lever apply pressure on the
syringe plunger and allow the brake
lever to slowly release to the fully
extended position remove the syringe
from the caliper and reinstall the bleep
cork screw use a lint-free rag to
immediately wipe off any excess fluid
open a clamp on the lever syringe pull
on the lever syringe plunger to create a
vacuum then gently push in on the
plunger to pressurize the system squeeze
and release the brake lever 10 times
allowing the lever to snap back repeat
this procedure several times until large
bubbles stop coming out of the lever be
careful not to pull out too hard on the
plunger or you will pull air past the
plunger seal once the large bubbles that
the lever have stopped push then release
the plunger one last time remove the
syringe and reinstall the bleed
corkscrew use a lint-free rag to
immediately wipe off any excess fluid
spray isopropyl alcohol or water onto a
lint-free rag and wipe off the brake
lever and caliper to remove any excess
brake fluid you may have missed before
remove the bleed block from the caliper
and reinstall the brake pads
reinstall your wheel according to the
manufacturer's instructions empty this
ranges into a sealed container and
dispose of the fluid properly used brake
fluid should be recycled or disposed of
in accordance to local and federal
regulations test the system pull on the
lever very firmly several times make
sure to look around the host nut on the
lever and the banjo bolt on the caliper
for any leaks take one last check of all
the bolts and fittings this completes
the avid elixir brake bleed procedure
