Suzuki Grand Vitara 2005 Owner's Manual

4A-5 Brake Control System and Diagnosis:
Substandard or contaminated brake fluid
CAUTION
!
Improper brake fluid, mineral oil or water in
the fluid may cause the brake fluid to boil or
the rubber components in the hydraulic
system to deteriorate.
If primary piston cups are swollen, then rubber parts
have deteriorated. The deterioration may also be
evidenced by swollen wheel cylinder piston cups on the
drum brake wheel.
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings. If excessive
fluid is found, replace the linings.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
