Front braking system bleeding (TE, TC)

The braking system must be bleed when, due to air in the circuit, the lever
stroke is long and spongy.
To bleed the system:
- Disconnect the brake caliper and position it so that the pipe fitting (pump to
caliper) is perpendicular to the ground.
- Remove the brake pump cover;
- Remove the anti-emulsion disc and fill up the tank with new fluid (DOT 4).
- Attach a clear hose to bleed the valve and run into a clear glass container as
shown in figure.
Make sure that the end of the hose is submerged in brake fluid during the
entire bleeding operation.
- Open the bleed valve on the caliper and pump the lever. Allow the pads to
contact the disc.
- During this operation, you'll notice that air bubbles will come out of the brake
pump reservoir. This is normal. Watch the hose. When new, clear fluid,
without bubbles, come out, close the bleed valve.
- Carefully pry the pads apart, using a soft pry bar, forcing them back into the
caliper housing.
WARNING: During bleeding the motorcycle handle bar must be
turned left. Thus, the pump tank will be higher, making easier the
braking system bleeding.
N.B. Should the motorcycle, due to a fall during a competition or
shop repairs, feature some elasticity of the brake lever stroke, with
a subsequent braking efficiency decrease, you'll have to repeat the
circuit bleeding as above described.
A screw to increase or decrease the clearance between lever and
pump cylinder is contained in the brake lever: this adjustment is
subjective and you'll use it according to your requirements.
