BRAKE TUBE AND HOSE
CAUTION:
●
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
●
Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
●
Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged
part is detected.
●
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.
●
Cover the open end of brake tubes and hoses when disconnecting to prevent entrance of dirt.
●
Refill with new brake fluid “DOT 3”.
●
Never reuse drained brake fluid.

Inspection after Installation
NFS000S2
CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
1.
Check brake lines (tubes and hoses) and connections for fluid leakage, damage, twists, deformation, con-
tacts with other parts, and loose connections. Replace any damage parts.
2.
While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately
5 seconds, then check each part for fluid leakage.

NFS000S4
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.
●
Never scratch the piston of master cylinder when installing/removing because the piston is
exposed. Check if any dust is not on the piston, and wash with brake fluid if needed.
●
Hold cylinder body when handing master cylinder. Never hold the piston because the piston might
be detached if pulled strongly.
REMOVAL
1.
Drain brake fluid. Refer to
.
2.
Disconnect brake fluid level switch harness connector.
3.
Disconnect master cylinder brake tubes, using a flare nut wrench.
4.
Remove master cylinder mounting nuts and remove master cylinder assembly from vehicle.
