Proceed as follows:
- Position the vehicle on a flat surface and on the
stand
- Loosen the two screws shown in the figure and
open the front brake fluid reservoir.
- Through the bleed screw on the brake calliper,
bleed the system using a hose of adequate diam-
eter.
- Collect the used fluid in a container.
- Pump on the brake lever to completely drain the
system of all used fluid.
- Tighten the bleed valve.
- Refill the brake system tank up to the maximum
level with the prescribed fluid.
- Attach the tube of the special tool to the bleed
fitting.
- Actuate the tool at the bleed fitting, at the same
time constantly topping up the brake system tank
to prevent air being drawn into the system, until no
more air escapes at the bleed fitting. The operation
is finished when only brake fluid comes out of the
bleed screw.
- Close the bleed screw and tighten to the prescri-
bed torque.
- Close the brake system tank.
N.B.
IF AIR CONTINUES TO COME OUT DURING THE BLEED
OPERATION, EXAMINE ALL THE FITTINGS. IF SAID FIT-
TINGS DO NOT SHOW SIGNS OF BEING FAULTY, LOOK
FOR THE AIR INPUT AMONG THE VARIOUS SEALS ON
THE PUMP AND CALLIPER PISTONS. WHEN CARRYING
OUT THE OPERATION, BRAKE FLUID MAY LEAK FROM
THE BLEED SCREW ON THE CALLIPER AND ON THE
DISC. IN THIS CASE; CAREFULLY CLEAN THE CALLIPER
AND DEGREASE THE BRAKE DISC.
