FRONT AXLE HUB ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

Note

When removing or installing the front disc brake caliper assembly, pushing back the disc brake piston may cause a large clearance between the brake pads and brake disc. When the brake pedal is depressed with a large clearance between the brake pads and the brake disc, DTCs C1341, C1342, C1343 and/or C1344 related to abnormal brake fluid pressure may be stored. Make sure to clear the DTCs after performing this step.
