a.

Install balance weight in the position shown in the figure at right.

b.

When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).

CAUTION:

●

Always use genuine Nissan adhesion balance weights.

●

Balance weights are unreusable; always replace with new
ones.

●

Do not install more than three sheets of balance weight.

c.

If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).

CAUTION:

Do not install one balance weight sheet on top of another.

3.

Start wheel balancer again.

4.

Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).

CAUTION:

Do not install more than two balance weights.

5.

Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.

●

If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.

Wheel balance (Maximum allowable unbalance):

Checking Brake Fluid Level and Leaks

ALS0005N

●

If fluid level is extremely low, check brake system for leaks.

Checking Brake Lines and Cables

ALS0005O

●

Check brake fluid lines and parking brake cables for improper
attachment, leaks, chafing, abrasions, deterioration, etc.

Changing Brake Fluid

ALS0005P

1.

Drain brake fluid from each bleed valve.

2.

Refill until new brake fluid comes out from each bleed valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid.
Refer to 

BR-9, "Bleeding Brake System"

 .

●

Refill with recommended Genuine Brake Fluid or equivalent
DOT 3 (US FMVSS No. 116).
Refer to
