Maintenance and Service11
The disc brakes have audible wear indica-
tors on the brake pads. If the brake pads
wear close to their service limit, the wear
indicator makes a very audible scraping
noise when the brake pedal is applied.
If you hear this scraping noise each time
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible.■ Breaking-in of New Brake
Pad s and LiningsWhen replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, the new parts must be
broken in as follows.

While maintaining a speed of 30 to 40 mph
(5 0 to 65 km/h), step on the brake pedal

force of approximately 33.7 lbf [150 N,
15.3 kgf]). 3. Drive the vehicle for approximately

220 yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking
brake to cool down. Repeat this proce-
dure.
