Brake Maintenance Procedures
Brake Bleeding Procedure (Front)
WARNING! Only use new brake fluid from and
airtight container. Fluid from open containers or
fluid previously used in the system will have
absorbed moisture, which will adversely affect
performance and must not be used.
WARNING! Brake fluid is highly toxic; keep
containers sealed and out of the reach of
children. If accidental consumption of brake fluid
is suspected, seek medical attention
immediately. If the brake fluid comes into
contact with the skin or eyes, rinse immediately
with plenty of water.
CAUTION: Brake fluid can damage plastic, as
well as painted and coated surfaces. Handle with
care and wipe up spills and wash the surfaces
immediately.
Tools Required:
• 8mm hex wrench
• 9mm hex wrench
• Vacuum bleeder
Fluid Required:
• DOT4 Brake Fluid
Bleeding
1. Fill the front master cylinder brake fluid
reservoir with DOT4 brake fluid. Keep the
reservoir full during this procedure.
CAUTION: Do not allow air to enter the
system during the bleeding procedure, or
the procedure will need to be repeated.
2. Open the front bleed screw. Tool: (9mm).
3. Slowly pull the brake lever toward the grip and
hold it until brake fluid flows out of the bleeder
and most of the air is gone. Tighten the
bleeder screw while holding the lever toward
the grip.
4. Repeat this sequence for the left and right
calipers until all the air is out of the system and
the lever is firm. Tool: (8mm).
