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.
4) Tools for disassembly operation:
1 Phillips screwdriver
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.

D: ASSEMBLY
1. PRECAUTIONS FOR ASSEMBLING
1) When assembling, be sure to use recommended brake
fluid.
2) Ensure that the inside wall of cylinder, pistons, and pis-
ton cups are free from dirt when assembling.
3) Be extremely careful not to damage, scratch, or dent
cylinder inside wall, pistons, and piston cups.
4) Do not drop parts. Never attempt to use any part that
has been dropped accidentally.
2. ASSEMBLING OPERATION
1) Assembling piston assembly:
Apply recommended brake fluid to inside wall of cylinder,
and to outer surface of piston assembly, and install piston
assemblies carefully into cylinder.
2) Assembling supply valve stopper or cylinder pin:
After installing piston into cylinder, push primary piston in
about 10 mm (0.39 in), using a rod, such as push rod then
assemble gasket and supply valve stopper or cylinder pin.
Tightening torque:
2.2±0.7 N⋅m (0.225±0.075 kg-m, 1.6±0.5 ft-lb)
CAUTION:
If the gasket and supply valve stopper are assembled
without pushing in the primary piston, scratches may
be caused on the secondary piston, and no pressure
may be built up in the secondary side. To avoid such
an error, be sure to push in the primary piston before
assembling these parts.
3) Assembling C-ring:
With primary piston pushed in slightly, attach C-ring by
using C-ring pliers.
NOTE:
After assembling, ensure that the C-ring is fitted securely
in the ring groove.
E: INSTALLATION
To install the master cylinder to the body, reverse the
sequence of removal procedure.
Tightening torque:
