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 rear disc brake pads, the brake pedal may feel soft due to clearance between the rear disc brake pads and rear disc. Depress the brake pedal several times until the brake pedal feels firm.
After replacing the rear disc brake pads, always perform a road test to check the braking performance and check for vibrations.
When removing or installing the front disc brake cylinder 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, DTC C140000 and/or C140A00 related to abnormal brake fluid pressure may be stored. Make sure to clear any DTCs after performing this procedure. (w/o vacuum brake booster)
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. (w/o vacuum brake booster)
After the ignition switch is turned off, the audio and visual system records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 2 minutes before disconnecting the cable from the negative (-) auxiliary battery terminal.
When the cable is disconnected from the negative (-) auxiliary battery terminal and the security lock setting has been enabled, multi-display operations will be disabled upon next startup unless the password is entered. Be sure to check the security lock setting before disconnecting the cable from the negative (-) auxiliary battery terminal.

HINT:

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

PROCEDURE

NOTICE:

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
Make sure to read the precautions of the electric parking brake system before removing the rear brake assembly.

(a) Wait 4 minutes after turning the ignition switch off to ensure that the skid control ECU is in sleep mode.

NOTICE:

When the brake pedal is depressed or the door courtesy switch is turned on even if the ignition switch is off, the brake control system activates. Therefore do not depress the brake pedal or open/close the doors until the reservoir level switch connector is disconnected.
Do not operate the electric parking brake switch assembly when the electric parking brake system is in rear brake pad replacement mode.

(d) In order to prevent pressurized brake fluid in the accumulator from being applied to the brake calipers, depress the brake pedal 40 times or more to return the pressurized brake fluid in the accumulator back to the brake master cylinder reservoir assembly.
