B: DISASSEMBLY
1. PRECAUTIONS FOR DISASSEMBLING
1) Remove mud and dirt from the surface of brake master
cylinder.
2) Prepare tools necessary for disassembly operation, and
arrange them neatly on work bench.
3) Clean work bench.

1 C-ring pliers
G4M0418
2. DISASSEMBLING PROCEDURE
1) Remove reserve tank.
2) Remove supply valve stopper. (only vehicle equipped
with ABS)
3) Remove filter and cylinder pin. (only vehicle equipped
with TCS)
4) Remove C-ring with C-ring pliers pushing in primary
piston slightly.
NOTE:
Piston may jump out from master cylinder.
5) Extract primary piston assembly and secondary piston
assembly.
CAUTION:

Do not disassemble the piston assembly; otherwise,
the spring set value may be changed.

Use brake fluid or methanol to wash inside wall of
cylinder, pistons and piston cups. Be careful not to
damage parts when washing. If methanol is used for
washing, do not dip rubber parts, such as piston cups,
in it for more than 30 seconds; otherwise, they may
become swelled.
C: INSPECTION
If any damage, deformation, wear, swelling, rust, and other
faults are found on the primary piston assembly, second-
ary piston assembly, supply valve stopper, or gasket,
replace the faulty part.
CAUTION:

The primary and secondary pistons must be
replaced as complete assemblies.

The service limit of the clearance between each pis-
ton and the master cylinder inner dia. is 0.11 mm
(0.0043 in).

When handling parts, be extremely careful not to
damage or scratch the parts, or let any foreign matter
get on them.
