Installing
WARNING!
Brake fluid is poisonous and must NEVER be
removed by siphoning with your mouth.
CAUTION!
Before pushing back the piston, siphon
some of the brake fluid out of the brake fluid
reservoir. Otherwise, particularly if reservoir
has been topped off, fluid will overflow and
cause damage.
To siphon brake fluid, always use a bleeder
bottle which is only used to siphon brake
fluid.
- Screw piston inward as far as it will go by turning threaded spindle
(arrow) clockwise and knurled section counterclockwise.
