Apply vacuum slowly and continuously while watch-
ing the gauge. The vacuum should stabilize momen-
tarily at 0.8 - 2.1 kPa (6 - 16 mmHg, 0.2 - 0.6 in.Hg).
lf the vacuum stabilizes (valve opens) below
0.8 kPa {6 mmHg, 0.2 in.Hg) or above 2.1 kPa
(16 mmHg, 0.6 in.Hg), install a new valve and retest.
Move the vacuum pump hose from the vacuum fit-
ting to the pressure fitting, and move the vacuum
gauge hose from the vacuum side to the pressure
side as shown.
Slowlv pressurize the vapor line while watching the
gauge. The pressure should be stabilize momentari
ly above 1.0 kPa (8 mmHg. 0.3 in.Hg).
. lf the pressure momentarily stabilizes (valve
opens) above '1.0 kPa (8 mmHg, 0.3 in.Hg), the
valve is OK.
. lf the pressure stabilizes below 1.0 kPa (8 mmHg,
0.3 in.Hg), install a new valve and retest.
Apply vacuum slowly and continuously while
watching the gauge. The vacuum should stabilize
momentarily at 0.7 - 2.0 kPa (5 - 15 mmHg, 0.2 - 0.6

PRESSURESIDE
Slowly pressurize the vapor line while watching the

. It the pressure momentarily stabilizes (valve
opens) at 1.3 - 4.7 kPa (10 - 35 mmHg, 0.4 - 1.4

Front Brake Pads
Inspection and Replacement
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.
5i110 Type:
NOTE: For 2056 type disassembly procedures. see page
19-'10.
Never use an air hose or dry brush lo clean brake
assgmblios.
Use an OSHA approved vacuum cleaner to avoid
breathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake hose bracket from the knuckle.
Remove the caliper bolt, and pivot the caliper up
out of the wav.

4. Remove the pad shim. pad retainers, and pads.
NOTE: When the caliper is equipped with an outer
pad shim, replace the shim together with the pads
5. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickno$:
Standard: 9.5 - 10.5 mm 10.37 - 0.41 in)
SerYico Limit 1.6 mm {0.06 in}
lf the brake pad thickness is less than the service
limit, replace the front Dads as a set.
