1997 SUBARU LEGACY torque

(2) Slowly depress the brake pedal and keep it
depressed. Then, open the air bleeder to discharge air
together with the fluid.
Release air bleeder for 1 to 2 seconds.
Next, with the bleeder closed, slowly release the brake
pedal.
Repeat these steps until there are no more air bubbles
in the vinyl tube.
Allow 3 to 4 seconds between two brake pedal opera-
tions.
CAUTION:
Cover bleeder with waste cloth, when loosening it, to
prevent brake fluid from being splashed over sur-
rounding parts.
NOTE:
Brake pedal operating must be very slow.
4) Bleed air from suction pipe through front RH caliper.
(1) Open the air bleeder.
(2) Keep pressing TCS OFF switch for 20 seconds or
more.
NOTE:
Ensure no air comes out from air bleeder.
(3) Close the air bleeder.
5) Bleed air through front LH caliper by operating brake
pedal. This is the same procedure as step 3).
6) Bleed air from suction pipe through front LH caliper.
This is the same procedure as step 4).
7) Bleed air through front RH and LH calipers by operat-
ing brake pedal. This is the same procedure as step 3).
Repeat steps 3) to 7) until air does no longer comes out.
8) Tighten air bleeders securely when bubbles are visible.
Air bleeder tightening torque:
8±1 N⋅m (0.8±0.1 kg-m, 5.8±0.7 ft-lb)
9) Bleed air through rear LH and RH caliper by operating
brake pedal. This is the same procedure as step 3).
10) Tighten air bleeders securely when bubbles are vis-
ible.
Air bleeder tightening torque:
8±1 N⋅m (0.8±0.1 kg-m, 5.8±0.7 ft-lb)
