Front Braking System Bleeding (Smr) - Husqvarna TE 250-450 Workshop Manual

DRAFT

Front braking system bleeding (SMR)

Bleed the braking circuit when the lever stroke gets stretchy due to the
presence of air inside the circuit. Work as follows:
- Remove the caliper and fit a 4 mm shim in place of the disc, fastening it by
an elastic;
- Fit the caliper and the pipe fastening unit perpendicular to the ground, and
support it conveniently;
- Remove fluid reservoir cap (1) on the handlebar and fill up with the new fluid
DOT4;
- Fit a transparent plastic pipe on the bleed valve of the caliper and plunge the
other end of the pipe into a basin (check to make sure that, during the whole
operation, the end of the pipe is fully plunged into the fluid);
- Open the bleed valve on the caliper and move the lever several times until the
fluid, clear and without bubbles, comes out of the pipe; now close the bleed
valve;
- Reassemble the pump cap on the handlebar and the brake caliper;
- Remove the brake pump from the handlebar and place it in vertical position,
in line with the piping;
- Reassemble the pump on the handlebar, carry our another bleeding action,
fill up with fluid, and tighten the valve on the caliper to the prescribed torque.
As the braking fluid is a very corrosive substance, in the case it comes
in contact with your eyes wash them abundantly with water.
During the bleeding of the braking circuit keep the handlebar turned
leftwards. This is the way to lift the pump tank and to make easier the
bleeding of the braking system
. I f the lever stroke gets stretchy and the braking action results as poor
in the case of falls during competitions, or after repair work in shops,
repeat the bleeding operation described above.
As the bleeding operation does not fully eliminate the air inside the
circuit, the small quantity of air remaining inside will be eliminated after
a short time of use of the brake. In this case however, the action of the
lever will be harder and the stroke shorter.
