Brake Bleeding Procedure (Rear)
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:
• 9mm hex wrench
• Vacuum bleeder
Fluid Required:
• DOT4 Brake Fluid
Bleeding
1. Fill the rear 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 rear caliper bleed screw (9mm).
3. Slowly press the brake lever down 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 brake lever down.
4. Repeat this sequence until all the air is out of
the system and the lever is firm.
