INSTALLATION

CAUTION / NOTICE / HINT

NOTICE:

• Immediately after installing the brake pads, the braking performance may be reduced. Always perform a road test in a safe place while paying attention to the surroundings.
• After replacing the front disc brake pads, the brake pedal may feel soft due to clearance between the front disc brake pads and front disc. Depress the brake pedal several times until the brake pedal feels firm.
• After replacing the front disc brake pads, always perform a road test to check the braking performance and check for vibrations.
• When the brake pedal is first depressed after replacing the brake pads or pushing back the disc brake piston, DTC C1214 may be stored. As there is no malfunction, clear the DTC. (for HV Model)
• While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch turns on. Therefore, when servicing the brake system components, do not operate the brake pedal or open/close the doors while the auxiliary battery is connected. (for HV Model)

HINT:

• Use the same procedure for the RH side and LH side.
• The following procedure is for the LH side.
