DISC PAD (REAR) REPLACEMENT

id041100800300

Note
•  There are two types of disc pad components, one equipped with double-sided adhesive tape and one without.

With Double-sided Adhesive Tape

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 electric parking brake motor gear unit connector.

7.  Move the caliper in the direction of the arrow shown in the figure.

8.  Remove the disc pad components from the mounting support.

9.  Clean the double-sided adhesive tape application area from the caliper, piston and disc pad components.

10.  Press in the piston using a commercially available disc brake expander tool. (See REAR BRAKE (DISC) REMOVAL/INSTALLATION.)

Caution
•  When pressing the piston into the caliper, the caliper internal parts could be damaged while rotating and pressing the piston. Be careful not to rotate the piston when pressing the piston into the caliper.

Caution
•  When the double-sided adhesive tape is affixed to the caliper and piston, the double-sided adhesive tape's adhesive surface may chap and become a source of noise when the caliper moves. When moving the caliper be careful not to allow the double-sided adhesive tape on the disc pad components to come in contact with the caliper and piston.

15.  Temporarily install the caliper securing bolt.

20.  End the maintenance mode. (See MAINTENANCE MODE.)

21.  Pump the brake pedal a few times to attach the double-sided adhesive tape on the disc pad components to the caliper and piston by applying pressure.

22.  Inspect the following items:

―  Disc pad projection does not contact piston and caliper
―  Brake drag


Without Double-sided Adhesive Tape

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 cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

3.  Remove the wheel and tire.

4.  Disconnect the electric parking brake motor gear unit connector.

5.  Remove in the order indicated in the table.

6.  Install in the reverse order of removal.

7.  End the maintenance mode. (See MAINTENANCE MODE.)

8.  After installation, pump the brake pedal a few times and inspect the following:

―  The disc pad projection is securely installed to the piston groove
―  Brake drag

Disc Pad, Bolt Installation Note

1.  Clean the exposed area of the piston.

2.  Push the piston in using the commercially available disc brake expand tool.

Caution
•  If the piston is pushed into the caliper while rotating the piston, the caliper internal parts could be damaged. Be careful not to rotate the piston when pushing the piston into the caliper.
