9 - BRAKING SYSTEM
WARNING
TAKE THE PRECAUTIONS LISTED BELOW:
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 PROLONGED PERIOD OF TIME.
3) DO NOT MIX TWO TYPES OR BRANDS OF FLUID FOR USE IN THE BRAKE. THIS REDUCES THE BRAKE
FLUID BOILING POINT AND MAY RESULT IN THE BRAKES NOT WORKING EFFICIENTLY. IN ADDITION,
IT MAY CAUSE DETERIORATION 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 WINDY CONDITIONS.
6) EXCEPT ON THE BRAKE LININGS AND THE DISK, USE ONLY BRAKE FLUID, ISOPROPYLIC ALCOHOL
OR ETHYL ALCOHOL FOR CLEANING BRAKE PARTS.
DO NOT USE ANY OTHER TYPE OF LIQUID FOR CLEANING THESE PARTS. PETROL, ENGINE OIL OR
ANY OTHER PETROLEUM DISTILLATE 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 COMES INTO CONTACT WITH THEM. CLEAN ANY REMAINS OF BRAKE FLUID THAT ACCIDEN-
TALLY COMES INTO CONTACT WITH THE LININGS OR WITH THE DISK WITH A SOLVENT WITH A HIGH
INFLAMMATION POINT. DO NOT USE ONE THAT LEAVES GREASY RESIDUES. CHANGE THE PADS
FOR NEW ONES IF THEY CANNOT BE CLEANED SATISFACTORILY.
8) BRAKE FLUID DESTROYS PAINTED SURFACES RAPIDLY. CLEAN UP ANY SPILT BRAKE FLUID IMME-
DIATELY.
9) IF ANY OF THE BRAKE SYSTEM PIPE SECURING SYSTEMS OR THE BLEED VALVE OPENS AT ANY
TIME, THE AIR MUST BE BLED FROM THE BRAKE SYSTEM.
