InTroduCTIon To BleedInG
When bleeding Juicy brakes, there are two main points to keep in mind:
1.
You are simply chasing bubbles out of the system.
2.
Gravity is your friend. (Liquid is heavier than gas, so bubbles always tend to rise.)
Avid's bleeding procedure allows the isolation of the caliper so it can be bled completely air free. Then, by pushing fluid from the
caliper up to the lever, you remove any air in the hydraulic line. From there, it's just a matter of purging those bubbles out of the
reservoir. Bleeding isn't hard once you understand what you are trying to do.
ProCedure overvIew
You will perform 3 basic operations when bleeding Juicy brakes:
1.
Bleed the caliper
2.
Bleed the hose
3.
Bleed the lever (master cylinder and reservoir)
Following this procedure gives you a perfectly bled, optimally performing Juicy brake. Enjoy!!

PrePare The SyrInGeS
a.
Fill one syringe 1/2 full with Avid Hi-Performance DOT Fluid and close the hose clamp. Leave the
other syringe empty and open.
B.
Now you are going to de-gas the fluid in the 1/2 full syringe. Getting all the air out of the fluid now
gives you the ultimate brake bleed.
Leave the hose clamp shut and pull down on the plunger. You will see bubbles appear from nowhere in
the fluid. That's all air that was trapped in the fluid. Pull on the plunger several times. When the bubbles
stop forming, open the clamp and carefully push the excess air and gas out. Try tapping the syringe as
you pull, to release more bubbles. Repeat several times.
Notes:
• Be careful not to pull too hard or you will pull air past the seal of the syringe.
• You never eliminate all the bubbles in the fluid, so after you have pulled a few times,
and the number of bubbles decreases, you are ready to move on to the next step.

PrePare The CalIPer and The lever
on The CalIPer
a.
Use the T-10 Torx wrench to remove the caliper bleed port screw from the
center of the banjo bolt.
B.
Make sure the fluid in the 1/2-full syringe is pushed all the way to the tip
(no air gap!), then screw into the caliper bleed port.
on The lever
a.
For Juicy models WITH pad contact knob, turn the knob all the way to the
"out" position. For a left lever, this would be all the way clockwise and for a
right lever all the way counterclockwise.
Note: Does not apply to juicy three or juicy five.
B.
Using a 4mm hex wrench, slightly loosen the lever clamp bolt(s) then rotate
the lever so the body of the lever points straight down – perpendicular with
the floor. You will need to loosen your shifter to allow the brake
lever down to this position.
C.
Remove the lever bleed port screw and install the empty syringe, leaving the
clamp on the syringe open.
d.
Squeeze the lever closed (against the bar) and fasten it with a rubber band.
This closes off the master cylinder and isolates the caliper, allowing the
removal of any air from the caliper only before moving on to the rest of
the system.
Important: Ensure that the reach adjuster is not adjusted so far out
that the lever blade is bottomed out on the lever body. Doing so can
make bleeding the brake impossible.
