WARNING
WHEN WORKING WITH THE DISK BRAKE, TAKE THE FO-
LLOWING PRECAUTIONS:
1) NEVER RE-USE BRAKE FLUID.
2) DO NOT USE FLUID FROM A CONTAINER THAT HAS
BEEN LEFT OPEN OR HAS BEEN LEFT UNUSED FOR A PRO-
LONGED PERIOD OF TIME.
3) DO NOT MIX TWO TYPES OR BRANDS OF FLUID FOR
USE IN THE BRAKE. THIS REDUCES THE BRAKE FLUID EVA-
PORATING POINT AND MAY RESULT IN THE BRAKES NOT
WORKING EFFICIENTLY. IN ADDITION, IT MAY CAUSE DE-
TERIORATION OF THE BRAKE PARTS.
4) DO NOT LEAVE THE RESERVOIR CAP OFF AT ANY TIME,
TO PREVENT CONTAMINATION OF THE FLUID.
5) DO NOT CHANGE THE FLUID IN RAINY OR VERY WIN-
DY CONDITIONS.
6) EXCEPT ON THE BRAKE LININGS AND THE DISK, USE
ONLY BRAKE FLUID, ISOPROPILIC ALCOHOL OR ETHYL AL-
COHOL FOR CLEANING BRAKE PARTS. DO NOT USE ANY
OTHER TYPE OF LIQUID FOR CLEANING THESE PARTS.
PETROL, ENGINE OIL OR ANY OTHER PETROLEUM DISTI-
LLATE WILL CAUSE RUBBER PARTS TO DETERIORATE. IF OIL
IS SPILT ON ANY PART, IT WILL BE DIFFICULT TO CLEAN
COMPLETELY AND MAY DETERIORATE THE RUBBER USED
IN THE DISK BRAKE.
7) ON HANDLING THE DISK BRAKE LININGS OR THE
DISK, TAKE CARE TO ENSURE THAT NO BRAKE FLUID CO-
MES INTO CONTACT WITH THEM. CLEAN ANY REMAINS
OF BRAKE FLUID THAT ACCIDENTALLY COMES INTO CON-
TACT WITH THE LININGS OR WITH THE DISK WITH A SOL-
VENT WITH A HIGH INFLAMMATION POINT. DO NOT USE
ONE THAT LEAVES GREASY RESIDUES. IF LININGS CAN-
NOT BE CLEANED SATISFACTORILY, CHANGE THEM FOR
NEW ONES.
8) BRAKE FLUID DESTROYS PAINTED SURFACES RAPIDLY.
CLEAN OFF ANY SPILT REMAINS IMMEDIATELY.
9) IF ANY OF THE BRAKE SYSTEM PIPE SECURING SYSTEMS
OR THE BLEED VALVE OPENS AT ANY TIME, THE AIR CAN BE
BLED FROM THE BRAKE SYSTEM PIPE.
