Inspection after Disassembly
Master cylinder

Check that there is no damage, friction, rusting, or pinholes on the cylinder inner wall, and replace if there
are any non-standard conditions.
Assembly
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall body and contact surface
of the piston assembly.
2. Insert the secondary piston assembly and primary piston
assembly into cylinder body in this order.
CAUTION:

Do not reuse the primary and secondary piston assem-
blies.

Be sure to replace the assembly without disassembling
the new inner kit.

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.
3. Perform a visual inspection of the secondary piston slit through
the tank boss hole on the secondary-side of the cylinder body,
and install the piston stopper.
4. Holding down the piston with the stopper cap, push the stopper
cap tabs so they are firmly into the cylinder grooves, then attach
the stopper cap.
CAUTION:
Do not reuse the stopper cap.
5. Apply brake fluid the grommet and attach to the cylinder body.
CAUTION:
Do not reuse the grommet.
6. Attach the attachment in the inner kit to the reservoir cap as
described in disassembly step 2.
7. Master cylinder assembly is fixed in the vise as described in
disassembly step 3.SBR089C

5. Push in the primary piston and remove the piston stopper from
the cylinder body secondary-side tank boss hole.
6. Remove the snap ring while pushing the primary piston in to pre-
vent the piston from popping out.
7. Holding the primary piston rod, pull the primary piston assembly,
the plate, and the guide straight out.
8. Remove the plate and guide from the primary piston.
CAUTION:
When removing the plate from the primary piston rod, make
sure the inside of the plate does not damage the rod.
9. Tap flange using a soft block such as wood, and carefully pull
the secondary piston assembly straight out to prevent cylinder
inner wall from being damaged.

INSPECTION AFTER DISASSEMBLY
Cylinder Body
CAUTION:
Use new brake fluid to clean. Do not use mineral oils such as gasoline or kerosene.

Check the inner wall of cylinder for corrosion, wear, and damage. If a malfunction is detected, replace cyl-
inder body.

Minor flaws caused by corrosion or a foreign material can be removed by polishing a surface of the inner
wall with a fine sandpaper. Replace cylinder body, if a malfunction is detected.
To r q u e M e m b e r
Check for wear, cracks, and damage. If a malfunction is detected, replace applicable part.
Piston
CAUTION:
The piston sliding surface is plated. Do not polish with sandpaper.

Check sliding pins and sliding pin boots for wear, damage, and cracks. If a malfunction is detected, replace
applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boots. Cover the piston end with
piston boot, and install cylinder-side lip on piston boot properly
into groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston, and press piston into cylinder body
by hand to assemble piston-side lip on piston boot properly into
a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.
