dirt, anti-freeze, etc. Extreme
care should be taken to clean the filler cap before refilling a system
with fluid. Parts should be washed clean in Declene and coated with new
brake fluid before assembly.
(4) A good brake fluid
should lubricate the moving
parts in the master cylinder and wheel cylinders. The life of
rubber cups is dependent upon this characteristic.
(5) A good brake fluid
should have no corrosive action on
metal parts. Pitting and rusting with resultant increased wear of rubber parts may
often be traced to the use of poor brake fluid.
(6) A good brake fluid must
be chemically stable and must have a high water tolerance. Cheap fluids
often separate under conditions of high or low temperature or
continued usage, and lose efficiency. Sludge is formed and corrosive
action accelerates. A good fluid
neutralizes or assimilates water which naturally accumulates in the
brake system. Failure to do this
leaves the water in concentrated form and results in corrosion and
pitting.
Delco
Brake Fluids exhibit all of the desirable |
characteristics outlined above
and, in addition, have proved themselves superior under actual operating
conditions. Delco Super 9 meets SAE
moderate duty specifications and Delco Super 11 meets SAE Heavy
Duty and Government 2-111 specifications. |
