5. While pushing primary piston, remove piston stopper through
secondary tank boss hole in the cylinder body.
6. Remove snap ring with pushing primary piston.
CAUTION:
Be careful not to pop out piston.
7. Holding rod of primary piston, remove primary piston assembly,
plate and guide assembly by pulling straight to prevent piston
cup from being caught by the inner wall of cylinder.
8. Remove plate and guide assembly from primary piston.
CAUTION:
Be careful not to damage rod from the inner wall of plate.
9. Tap flange using a soft block such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder inner
wall from being damaged.
INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for damage, wear, corrosion, and pin holes. Replace cylinder body if nec-
essary.
ASSEMBLY
CAUTION:
Never use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.
Make sure that there is no foreign material such as dirt and dust on the inner wall of cylinder, pis-
ton, and piston cup. Be careful not to damage parts with a service tool when assembling.
Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to the inner wall of cylinder body, primary pis-
ton assembly and secondary piston assembly.
2. Insert secondary piston and primary piston assembly into cylin-
der body in this order.
CAUTION:
Pay attention to the orientation of piston cup, and insert
straight to prevent cup from being caught by the inner
wall of cylinder.
Always replace inner kit as a set.

3. Set the slit of secondary piston towards the piston stopper
mounting hole of cylinder body while pushing in the primary pis-
ton. Then install the piston stopper through the slit of secondary
piston.
4. Insert plate and guide assembly into cylinder body.
CAUTION:
Be careful not to damage rod of primary piston.
Pay attention to the orientation of guide assembly.
Do not drop O-ring.
Be careful the guide and/or plate are not inserted at an
angle to cylinder inner wall.
5. Be careful not to damage rod of primary piston with the cloth.
Then insert snap ring to cylinder body while pushing primary pis-
ton.
CAUTION:
Make sure that snap ring is securely engaged in cylinder
body inner diameter groove.
6. Apply brake fluid to a grommet, and press it into reservoir tank to install.
7. Install reservoir tank to cylinder body.
CAUTION:
Pay attention to the orientation of reservoir tank. Make sure
reservoir tank is fully seated on master cylinder.

CAUTION:
Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed
air.
While removing brake pad or cylinder body, do not depress brake pedal because piston will pop
out.
It is not necessary to remove torque member mounting bolts and brake hose except for disassem-
bly or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake
hose is not under tension.
Do not damage piston boot.
If any shim is subject to serious corrosion, replace it with a new one.
Keep rotor free from brake fluid.
When replacing brake pad, replace shim with a new one.
Removal and Installation of Brake PadEFS006JP
REMOVAL
1. Remove tires from vehicle.
2. Remove sliding pin bolt (lower side).
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.
INSTALLATION
1. Apply AS-880N grease or equivalent to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.
CAUTION:
When installing pad retainer, attach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.
CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-24, "
Compo-
nents" .
