Warning

•  If the vehicle is driven without ending maintenance mode, it could result in an accident. After performing the maintenance mode work, always end maintenance mode.

Caution

•  Do not empty the brake fluid in the rear brake caliper. Otherwise, the electronically controlled brake unit could be damaged.

•  When disconnecting the brake hose from the rear brake caliper, always plug and seal the rear brake caliper so that brake fluid does not leak.

•  A new rear brake caliper has been plugged sealing off the brake fluid. For this reason, remove the plug of the rear brake caliper directly before installing the rear brake caliper to the vehicle. Other than for this, do not remove the plug of the rear brake caliper.

•  When performing the procedure while the vehicle is on the ground, block the front and rear wheels using wheel blocks. Otherwise, the vehicle may move when the electric parking brake is released.

Note

•  When in maintenance mode, the clearance between the disc pad and the disc plate expands.

•  When the maintenance mode is completed, perform the electric parking brake automatic adjustment.

•  With the electric parking brake automatic adjustment, the electric parking brake motor gear unit operation time is longer than normal.

1.  Switch to the maintenance mode. (See MAINTENANCE MODE.)

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

3.  Remove the wheel and tire. (See WHEEL AND TIRE REMOVAL/INSTALLATION.)

Caution

•  Do not allow moisture, dust or foreign matter to penetrate the connector as it could cause the electric parking brake motor gear unit to malfunction.

4.  Disconnect the electric parking brake motor gear unit connector. (See ELECTRIC PARKING BRAKE MOTOR GEAR UNIT REMOVAL/INSTALLATION.)

5.  Remove in the order indicated in the table.

6.  Install in the reverse order of removal.

7.  Connect the electric parking brake motor gear unit connector. (See ELECTRIC PARKING BRAKE MOTOR GEAR UNIT REMOVAL/INSTALLATION.)

8.  After installation, add brake fluid, bleed the air, and inspect for fluid leakage. (See BRAKE FLUID AIR BLEEDING.)

9.  Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)
