rear brakes SUBARU LEGACY 1999 Service Repair Manual

1. General
A: PRECAUTION
When servicing clutch system, pay attention to the
following items.
1. MECHANICAL APPLICATION TYPE
1) Check the routing of clutch cable for smooth-
ness.
2) Excessive tightness or looseness of clutch
cable have a bad influence upon the cable durabil-
ity.
3) Apply grease sufficiently to the connecting por-
tion of clutch pedal.
4) Apply grease sufficiently to the release lever
portion.
5) Position clutch cable through the center of toe
board hole and route it smoothly. Adjustment is
done by moving the outer cable.
6) Make sure not to let the clutch chatter when
starting forward or rearward. If clutch chattering
occurs, readjust so that the bend of clutch outer
cable becomes flatter.
2. HYDRAULIC APPLICATION TYPE
1) Check fluid level using a scale on outside of
reservoir tank. If the level is below ªMINº, add
clutch fluid to bring it up to ªMAXº.
Recommended clutch fluid:
FMVSS No. 116, fresh DOT3 or DOT4
brake fluid
CAUTION:
IAvoid mixing different brakes of brake fluid
to prevent degradation of the fluid.
IBe careful not to allow dirt or dust to get into
the reservoir tank.
IUse fresh DOT3 or DOT4 brake fluid when
refilling fluid.
S2M0351A
2) Make sure that brake fluid does not leak from
master cylinder, operating cylinder and piping.
3) Apply grease sufficiently to the release lever
pinion.
4) Check for proper clutch disengagement and
clutch pedal return ability.
2. On-car Service
A: ADJUSTMENT
1. MECHANICAL APPLICATION TYPE
1) Remove release lever return spring from lever
(Models without hill holder only).
2) Adjust spherical nut so that the play is within the
specified value at the lever end (center of spheri-
cal nut).
Play:
3Ð4mm(0.12 Ð 0.16 in)
Full stroke:
24 Ð 26 mm (0.94 Ð 1.02 in)
CAUTION:
Take care not to twist the cable during adjust-
ment.
G2M0234
3) Upon completion of adjustment, securely lock
spherical nut with lock nut.
G2M0235
4) Install return spring on lever (Models without hill
holder only).
NOTE:
Hook the long hook side of the return spring with
the lever (Models without hill holder only).

stall speed range on the tachometer scale.
3) Place the wheel chocks at the front and rear of
all wheels and engage the parking brake.
4) Move the manual linkage to ensure it operates
properly, and shift the select lever to the 2 range.
5) While forcibly depressing the foot brake pedal,
gradually depress the accelerator pedal until the
engine operates at full throttle.
B3M0286B
6) When the engine speed is stabilized, read that
speed quickly and release the accelerator pedal.
7) Shift the select lever to Neutral, and cool down
the engine by idling it for more than one minute.
8) Record the stall speed.
9) If stall speed in 2 range is higher than
specifications, low clutch slipping and 2-4 brakeslipping may occur. To identify it, conduct the same
test as above in D range.
10) Perform the stall tests with the select lever in
the R range.
NOTE:
IDo not continue the stall test for MORE THAN
FIVE SECONDS at a time (from closed throttle,
fully open throttle to stall speed reading). Failure to
follow this instruction causes the engine oil and
ATF to deteriorate and the clutch and brake to be
adversely affected.
Be sure to cool down the engine for at least one
minute after each stall test with the select lever set
in the P or N range and with the idle speed lower
than 1,200 rpm.
IIf the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.Stall speed (at sea level):
2200 cc 2,200 Ð 2,600 rpm
2500 cc 2,200 Ð 2,600 rpm
OUTBACK 2,300 Ð 2,700 rpm
