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 pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
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.

Disassembly
CAUTION!
• Clean around caliper with brake fluid before disassembly.
• Be careful not to damage inside (bore side) of cylinder.
1) Remove piston with air blown into flexible hose bolt installation hole.
WARNING!
Do not apply too highly compressed air
which will cause piston to jump out of
cylinder. Place a cloth (1) to prevent piston
from damage. It should be taken out
gradually with moderately compressed air.
Do not place your fingers in front of piston
when using compressed air.
2) Remove cylinder boot.
3) Remove piston seal using a thin blade like a thickness gauge, etc.
4) Remove bleeder plug and cap from caliper.
