1991 MITSUBISHI MONTERO brake

adjusting screw turns freely in lever.
2) Using torque wrench, tighten band adjusting screw to 30
INCH lbs. (3.5 N.m). Back off adjusting screw 6 turns. Hold adjusting
screw in this position, and tighten lock nut to 25 ft. lbs. (34 N.m).
3) Reinstall oil pan using new gasket. Tighten pan bolts to
150 INCH lbs. (17 N.m). Refill with specified transmission fluid.
KICKDOWN SERVO
ECLIPSE, GALANT, MIRAGE, PRECIS & 3000GT
1) Remove all dirt and grease around kickdown servo switch.
Remove snap ring and kickdown servo switch.
2) To prevent servo piston from turning, install Adapter
(MD998915) and Kickdown Servo Wrench (MD998914) so tab of wrench
engages with notch of piston. See Fig. 2.
CAUTION: DO NOT push servo piston inward while installing adapter
and servo wrench. Install adapter in brake pressure port by
hand ONLY. DO NOT use wrench to tighten adapter.

3) Loosen lock nut to "V" channel of adjuster rod. See
Fig. 2 . Tighten inner section of Kickdown Service Adjustment Assembly
(MD998916) until it contacts lock nut.
4) Install outer section of kickdown service adjustment
assembly on lock nut. Rotate outer section to left and inner section
to right to contact lock nut with inner section.
5) Using an INCH lb. torque wrench on inner section, tighten
inner section to 86 INCH lbs. (9.8 N.m), and then loosen inner
section. Tighten inner section to 43 INCH lbs. (4.9 N.m).
CAUTION: Before tightening lock nut with torque wrench, tighten it
by hand until it contacts piston. If torque wrench is used

problem symptoms. For model-specific Trouble Shooting,
refer to DIAGNOSTIC, or TESTING articles available in the
section(s) you are accessing.
