CHECK OPERATION OF FRONT DISC
BRAKE PAD WEAR SENSOR
Disconnect the connector for the front disc
brake pad wear sensor, place the terminal for
the wiring side coupling to earth and check
that the relevant warning light in the instru­
ment panel comes on.
E l CHECK CONDITION OF REAR DISC
M
BRAKE PADS
(Bravo 1998 20v)
Remove one of the rear wheels and check the
thickness of the friction material through the
slit in the brake caliper; the minimum permis­
sible thickness if 1.5 mm. Check that the
wear of the pads is even. Visually inspect the
condition of the brake caliper dust boots.
Check the condition of the brake disc work
surfaces (for wear or deep grooves). Notify
the Customer of the need to replace or re-
grind (in the case of a brake pad) one of the
components which has been checked.
Q CHECK CONDITION AND WEAR OF
REAR DRUM BRAKES
With one of the rear wheels removed, remove
the brake drum. Check the thickness of the
brake linings: the minimum permissible thick­
ness is 1.5 mm. Also check that there is no
fouling from oil or grease. Check the effi­
ciency of the shoe return device and the au­
tomatic recovery of the clearance between
the drum and the shoes. Check the efficiency
of the wheel cylinders (sliding of pistons,
condition of dust boots). Check the condi­
tion of the drum work surfaces (for wear or
grooves). Notify the Customer of the need to
replace or skim (in the case of brake drums)
one of the components which has been
checked.
If there is an inspection window in the brake
drum it is possible to check the thickness of
the brake linings without having to remove
the actual drum.
