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:
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
1. Drain brake fluid.
2. Remove fluid level sensor harness connector.
3. Using a flare nut wrench, disconnect master cylinder assembly and brake tube.
4. First remove master cylinder assembly mounting nuts. Then remove master cylinder assembly.
INSTALLATION
1. Connect brake tube to master cylinder assembly and temporarily tighten flare nut by hand.
2. Connect master cylinder assembly to brake booster assembly and tighten mounting nuts to the specified
torque.
3. Tighten brake tube flare nuts.
4. Refill with new brake fluid and bleed air from the brake piping.
