3. HYDRAULIC BRAKE BLEEDING PROCEDURE
Escaping fluid under pressure can
penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure
before disconnecting hydraulic or other
lines. Tighten all connections before
applying pressure.
Search for leaks with a piece of cardboard.
Protect hands and body from high
pressure fluids.
※
If an accident occurs, see a doctor
immediately. Any fluid injected into the skin
must be surgically removed within a few
hours or gangrene may result.
Doctors unfamiliar with this type of injury
should reference a knowledgeable medical
source.
Two people are required to bleed brake
system oil, one to operate brake valve and
other to open and close bleed screws.
