- DURING THE OPERATIONS, THE VEHICLE MUST BE ON
THE STAND AND LEVEL.
N.B.
DURING PURGING FREQUENTLY CHECK THE LEVEL TO
PREVENT AIR GETTING INTO THE SYSTEM THROUGH
THE PUMP.
WARNING
- BRAKING CIRCUIT FLUID IS HYGROSCOPIC.
IT ABSORBS HUMIDITY FROM THE SUR-

IF THE LEVEL OF HUMIDITY IN THE BRAKING
FLUID EXCEEDS A GIVEN VALUE, BRAKING
EFFICIENCY WILL BE REDUCED.
THEREFORE, ALWAYS USE FLUID FROM
SEALED CONTAINERS.
UNDER NORMAL DRIVING AND CLIMATIC
CONDITIONS YOU SHOULD CHANGE THIS
LIQUID EVERY TWO YEARS.
IF THE BRAKES ARE USED INTENSELY AND/
OR IN HARSH CONDITIONS, CHANGE THE
FLUID MORE FREQUENTLY.
CAUTION
WHEN CARRYING OUT THE OPERATION, BRAKE FLUID
MAY LEAK FROM BETWEEN THE BLEED SCREW AND ITS
SEAT ON THE CALLIPER.
CAREFULLY DRY THE CALLIPER AND DE-
GREASE THE DISC SHOULD THERE BE OIL
