NOTE: Stake the cylinder in the position opposite
from where the stake was removed during disas-
semoly.
Be careful not to damage
the bushing when inserting
the cylinder end.
49. Select the 32 mm shim(s) ('96 -'97 model only)'
NOTE: Only reinstall the original 32 mm shim(s)
when the steering gearbox is reassembled without
replacing the pinion shatt, valve housing, and gear
box housing with new ones.
lf the pinion shaft, valve housing, and gearbox
housing are replaced, select the new shim{s) as fol-
lows.
Shim selection:
a. Set the four 32 mm shims on the bearing surface of
the gearbox housing. Total thickness of the four
shims should equal no more than 0 70 mm'
Shim set: four 32 mm shims (Thickness: 010 mm'
0.15 mm, 0.20 mm, 0.25 mm respectivelyl
CAUTION: Th€ four 32 mm shims do not have
thickness identification marks Measure the thick-
ness of each shim using a micrometsr, and mark
the shim lor identification.

Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster, Replace the brake booster as an assembly
if it does not work properly or if there are signs of
leakage.
Piston Cup and Pressure Cup Inspeqtion
. Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leak-
age.
Replace the master cylinder as an assembly if
the pedal does not work properly or if there is
damage or signs of fluid leakage.
. Check for a difference in brake pedal stroke
between quick and slow brake applications.
Replace the master cylinder if there is a differ-
ence in oedal stroke.
Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is dam-
aged or leaking.
Caliper Piston Seal and Piston Boots
Check brake ope.ation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes
drag. or there is damage or signs of fluid leakage,
disassemble and inspect the brake caliper. Replace
the boots and seals with new ones whenever the
brake caliDer is disassembled.
Wheol Cylindor Piston Cup and Dust Cover
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes
drag, or there is damage or signs of fluid leakage,
disassemble and inspect the wheel cylinder. lf nec-
essary, replace the wheel cylinder as an assembly.

to prevent damaging it when pivoting the caliper
down.
Pivot the caliper down into position, then install the

lnstall the brake hose bracket on the knuckle
NOTE: Inspect the brake hose for interference or
twisting.
Depress the brake pedal several times to make sure
the brakes work. then test-drive.
NOTE: Engagement of the brake may require a
greater pedal stroke immediately after the brake
pads have been replaced as a set. Several applica-
tions of the brake pedal will restore the normal
Dedal stroke.
After installation. check for leaks at hose and line
joints or connections, and retighten if necessary.

NOTE: There are two types of front brake calipers:
The caliper types can be identified by the "5410" or"2056" stamped on the caliper body as shown below.
Check the type of the brake caliper before servicing.
