winding radius 100 mm (3.94 in) or larger.
2. After confirming that the grommet is properly positioned, push
the grommet securely into the hole.

Hood Lock Control InspectionEIS000KI
NOTE:
If the hood lock cable is bent or deformed, replace it.
1. Confirm hood lock secondary latch securely engages secondary
striker by releasing it from a height of approximately 200 mm
(7.87 in).
2. Confirm front end of the hood rises by approximately 20 mm
(0.79 in) when pulling the hood opener. Also confirm hood
opener returns to the original position.
3. Confirm hood lock has is properly lubricated. If necessary, apply
"Body Grease" at the point shown in the figure.

PRECAUTIONSPFP:00001
Precautions for Models with SRS Air Bag and Pre-Tensioner Seat BeltEFS000BY
WA RN ING:
lBefore removing and installing components and harnesses of SRS air bag and seat belt pre-ten-
sioner system, turn ignition switch OFF, disconnect battery ground cable, and wait at least 3 min-
utes. (This discharges electricity held in the air bag sensor unit's additional power circuit.)
lDo not use pneumatic or electric tools to remove and install the components.
lDo not solder SRS air bag and seat belt pre-tensioner system harnesses when making repairs.
Make sure harness is not pinched and there is no contact with other components.
lWhen checking the SRS air bag and the seat belt pre-tensioner circuit or the components of each
system, do not use an electric tester such as a circuit tester. (This is to prevent accidental trigger-
ing caused by the weak electric current of a tester.)
lNever insert foreign material (such as a screwdriver) in the air bag module and pre-tensioner seat
belt connectors. (The units may be actuated by mistake by static electricity.)
lSeat belt pre-tensioner and SRS air bag harnesses can be distinguished from other harnesses by
their yellow connectors.
lWhen servicing, refer to “SB Seat Belt” and “SRS Air Bag” for safety.
Precautions for Brake SystemEFS000BZ
lClean dust on brake pads, shoes, drums, and back plates with a vacuum dust collector. Do not blow with
compressed air.
lRecommended fluid is brake fluid “DOT 3” or “DOT 4”.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas such as the body. If brake fluid is splashed or spilled
on paint, wipe it off and flush the area with water immediately.
lUse only clean brake fluid when cleaning master cylinder and disc brake components.
lNever use mineral oils such as gasoline or kerosene to clean. They will ruin the rubber parts and cause
improper operation.
lAlways use a flare nut torque wrench to securely tighten brake
tube flare nuts.
lThe brake system is an important safety part. If a brake fluid
leak is detected, always disassemble the related parts. If dam-
age, deformation or excessive wear is detected, replace
affected parts with new ones.
lBefore staring operation, be sure to turn the ignition switch OFF
and disconnect the ABS actuator and control module connector
or battery cables.
lWhen installing brake piping, be sure to check torque.SBR686C

REMOVAL
CAUTION:
lDo not allow brake fluid to spill or splash on painted surfaces. Brake fluid can seriously damage
paint. If it gets on a painted surface, wipe it off immediately and wash with water.
lDo not bend or twist the brake hose sharply, or strongly pull it.
lCover brake fluid line connections to prevent dust and other foreign material from entering.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel while depressing the brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from the brake hose.
4. Remove union bolts and disconnect caliper assembly from the
brake hose.
5. First remove lock spring from brake tube and strut mounting
positions. Then remove brake hose.

ASSEMBLY
CAUTION:
lNever use mineral oils such as kerosene or gasoline during the cleaning and assembly processes.
lBe sure there is no foreign material on the cylinder inner wall, piston, and cup seal. Be careful not
to damage parts with a service tool during assembly.
lDo not drop the parts. Do not use any dropped parts.
1. Apply brake fluid to the inner wall of cylinder body and contact
surface of the piston assembly. Then insert secondary piston
assembly and primary piston assembly into cylinder body in this
order.
CAUTION:
lDo not reuse primary and secondary piston assemblies.
lAlways replace the inner kit as an assembly.
lPay attention to orientation of the piston cup. Insert it
straight in order to prevent it from catching on the cylin-
der's inner wall.
2. Visually check secondary piston slit position through cylinder
body secondary tank boss hole and install piston stopper.
3. Hold piston with stopper cap. Press stopper cap in until its tabs
fully engage groove on the cylinder body.
CAUTION:
Do not reuse stopper cap.
4. Apply brake fluid to grommet before pressing it into cylinder
body.
CAUTION:
