Hydraulic Brake Fluid & Bleeding Precautions
1.
Do not mix different types or brands of brake
fluid.
2.
Clean the top and cap of brake fluid containers
before opening.
3.
Do not use brake fluid which is contaminated or
that is cloudy, opaque, an emulsion, separated
into layers or contains moisture.
4.
Always store brake fluid in the original container
and keep airtight. Do not use (reuse) brake fluid
containers for any other purpose.
5.
Use only new brake fluid for bleeding and
cleaning of brake system parts, as applicable.
6.
Never save or reuse brake fluid once it has been
in any brake system.
7.
Clean the filler cap and top of master cylinder
before removing cap.
8.
Do not open master cylinder in a dusty area or
where rain, snow and other contaminants can
enter the fluid.
9.
Drain and flush the entire system if the fluid in
the master cylinder looks dirty, cloudy, is
emulsified, separated into layers or contains
water or other foreign liquid.
10.
Before
bleeding,
make
all
necessary
adjustments to pedal travel and repairs on lines,
hoses, cylinders, etc.
11.
Clean off bleeder screws
before
bleeding
brakes.
12.
Do not use brake bleeding equipment for any
other purpose.
13.
As applicable, use only pressure bleeders which
prevent aeration of fluid. Pressure bleeder must
be set to 14.5-17.4 psi (100-120 kPa). Higher
pressure can cause fluid aeration. Be sure that
pressure bleeder is in safe operating condition.
14.
Before attaching pressure bleeder to master
cylinder, fill cylinder completely full, and also fill
the bleeder hose with fluid.
15.
Follow brake bleeding procedures exactly as
described.
