BRAKE
INSPECTION
1. INSPECT BRAKE LINE PIPES AND BOOTS
HINT:
Inspect in a well±lighted area. Inspect the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before inspecting the front
brake.
(a) Check all brake lines and hoses for:

Damage

Wear

Deformation

Cracks

Corrosion

Leaks

Bends

Twists
(b) Check all clamps for tightness and connections for leak-
age.
(c) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT AND REAR BRAKE PADS AND
DISCS
(Front pads: See page BR±25)
(Rear pads: See page BR±34)
HINT:
If a squealing or scraping noise occurs from the brake during
driving, check the pad wear indicator.
If there are traces of the indicator contacting the disc rotor, the
disc pad should be replaced.

(a) Preconditions
The monitor will not run unless:

MIL is OFF

Fuel level is approximately 1/2 to 3/4

Altitude is 7,800 feet (2,400 m) or less

Engine Coolant Temperature (ECT) is between 4.4°C and 35°C (40°F and 95°F)

Intake Air Temperature (IAT) is between 4.4°C and 35°C (40°F and 95°F)

Cold Soak Procedure has been completed

Before starting the engine, the difference between ECT and IAT must be less than 7°C (13°F)
HINT:
Examples:

Scenario 1
ECT = 24°C (75°F)
IAT = 16°C (60°F)
Difference between ECT and IAT is 8°C (15°F)
" The monitor will not run because difference between ECT and IAT is higher than 7°C (13°F)

Scenario 2
ECT = 21°C (70°F)
IAT = 20°C (68°F)
Difference between ECT and IAT is 1°C (2°F)
" The monitor will run because difference between ECT and IAT is less than 7°C (13°F)
The readiness test can be completed in cold ambient conditions (less than 40°F / 4.4°C) and/or at
high altitudes (more than 7,800 feet / 2,400 m) if the drive pattern is repeated a second time after cycl-
ing the ignition off.
(b) Drive Pattern
(1) Connect the OBD II scan tool to DLC3 to check monitor status and preconditions (refer to (a)).
(2) Release pressure in fuel tank by removing the fuel tank cap and then reinstall it.
(3) Start the engine and allow it to idle until ECT becomes 75°C (167°F) or higher.
(4) Run the engine at 3,000 rpm for approximately 10 seconds.
(5) Allow the engine to idle with the A/C ON (to create slight load) for 15 to 50 minutes.
NOTICE:
If the vehicle is not equipped with A/C, put a slight load on the engine by doing the following :

Securely set the parking brake.

Block the drive wheels with wheel chocks.

Allow the vehicle to idle in drive for 15 to 50 minutes.
