SAFETY INFORMATION
Brakes are a safety-critical item on a bicycle. Improper
setup or use of brakes can result in loss of control or an
accident, leading to a severe injury.
Avid brakes are a performance product that offer increased
stopping power over brakes to which you are familiar. This
greater power requires less effort to lock-up a wheel when
braking. A wheel lockup might cause you to lose control and
possibly cause injury.
It's your responsibility to learn and understand proper brak-
ing techniques. Consult the owner's manual for your bicycle
and a professional bike dealer.
Practice your riding and braking techniques on a lat and
level surface prior to aggressive riding.
The effectiveness of braking is dependent on many condi-
tions over which SRAM has no control. These include the
speed of the bicycle, type and condition of riding surface,
braking lever force, proper installation and maintenance
of brakes, brake lines, hydraulic luid, levers, brake pads,
condition of the bike, weight of the rider, proper braking
techniques, weather, terrain, and a variety of other factors.
Avid brakes and levers are not intended for use on any
motorized bicycle or vehicle. Such use could result in a
serious personal injury.
ALWAYS RIDE UNDER CONTROL
Remember, it takes longer to stop in wet conditions. To
reduce the possibility of an accident and minimize trail ero-
sion, you should avoid locking-up your wheels.
Avid disc brakes are designed as a system. Do not use
components from a manufacturer other than Avid within the
system.
Do not touch the braking surface of any rotor with your bare
hands, because the oils from your ingers will degrade its
performance. Always wear gloves, or handle the rotor by
its spokes.

Hydraulic Disc Brake Hose Length Adjustment & Bleed Guide
Avid disc brake rotors are compatible with 44 mm, 6-bolt
international standard disc hubs.
We recommend 32 or 36-spoke wheels with a 3 or 4 cross
spoke lacing pattern. Contact your speciic wheel manufac-
turer for more speciications.
DO NOT USE RADIALLY SPOKED WHEELS.
Use only DOT 4 or DOT 5.1 luids with AVID disc brakes.
DOT 5.1 luids provide enhanced braking performance.
Do not use a luid other than the DOT luids suggested.
Doing so will damage the system and make the brakes
unsafe to use.
DOT luids will damage painted surfaces. If any luid comes
in contact with a painted surface (i.e. your frame), wipe it off
immediately and clean with isopropyl alcohol.
Do not allow any brake luid to come in contact with the
brake rotors. If this occurs, clean the rotors with isopropyl
alcohol.
Do not allow any brake luid to come in contact with the
brake pads. If this occurs, the pads are contaminated and
must be replaced.
Used DOT luid should be recycled or disposed of in ac-
cordance to local and federal regulations.
NEVER pour used DOT luid down a sewage or drainage
system or into the ground or a body of water.
WARNING
Disc brakes become very hot during use. Do not touch the
caliper or rotor immediately after use. Make sure the brake
has cooled down before making any adjustments.

Hydraulic Disc Brake Hose Length Adjustment & Bleed Guide
INTRODUCTION
Avid brakes are the most powerful and precise hydraulic brakes on the market. A key reason behind this is the ability to
optimize brake performance with a perfect bleed. The goal of bleeding is to remove any air that is trapped in the hose,
caliper, or lever. Air trapped in a hydraulic brake system degrades the performance of the brake. This manual will walk you
through our simple bleed procedure. Regardless of which Avid brake you are using, the steps for hose length adjustment
and bleeding are basically the same. In the case where a speciic model has unique features/procedures, so we'll show
you those steps too. Before you know it, you'll be back on the trail.
Note: Avid brakes come with hoses attached and bled. If you don't need to change the hose length, you do not need to
bleed the system prior to installation.
Juicy 3: Hose shortening can be performed at either the lever or the caliper on Juicy 3 brakes. However, shortening the
hose at the lever end will allow for an easier bleed.
TOOLS NEEDED
•
Safety glasses
•
Rubber gloves
•

HANDLING DOT FLUIDS
•
Avid highly recommends the use of rubber gloves when handling DOT luids.
•
DOT FLUIDS WILL DAMAGE PAINTED SURFACES! If any luid comes in contact with a painted surface (i.e. your frame)
or printing on the brakes, wipe it off immediately and clean with isopropyl alcohol or water. REMOVAL OF PAINT AND/
OR PRINTING BY DOT FLUID IS NOT COVERED UNDER WARRANTY!
•
Do not allow any brake luid to come in contact with the brake pads. If this occurs, the pads are contaminated and must
be replaced.
•
For best results, use only Avid Hi Performance DOT Fluid. If Avid luid is not available, only use DOT 4 or 5.1 luid.
•
Used DOT luid should be recycled or disposed of in accordance to local and federal regulations.
•
NEVER pour used DOT luid down a sewage or drainage system or into the ground or a body of water.
