Parts specialist Blue Print has highlighted a problem that can occur when replacing the rear brake pads on Honda Civic models.  

The issue is rear brake failure after replacement of the rear brake pads, or any other repair work involving removal of the rear brake caliper. This can result in over-extension of the rear brake caliper piston, which can be identified if diagnostic trouble codes have been set. These include C1110-96 (Left Hand Electric Parking Brake Actuator Malfunction) and/or C1111-96 (Right Hand Electric Parking Brake Actuator Malfunction); this could indicate that the piston has been over extended. Blue Print says if the brake caliper piston is found to be over extended, the caliper should be replaced. 

The issue can also cause damage to the wiring harness or connector.

The problem occurs because the correct repair procedure has not been followed, leading to a failure of the rear brakes, which has been identified as the brake caliper or harness connector becoming damaged during the repair.

For an effective replacement, before removing the brake caliper, the brake system must be set in the ‘Brake Pad Maintenance’ mode using a suitable diagnostic tool. Then the caliper wiring harness must be disconnected, to prevent accidental operation or damage to the harness during the repair.

After all the work has been carried out, the technician should ensure that the brake caliper is fully installed, including all fixings and the brake caliper actuator wiring loom, before resetting the brake system out of the maintenance mode or operating the parking brake.

The Blue Print Rear Pad set for the Civic is: ADH242101. This fits the FC1, FC9, FC8, FK6, FK7, FK8, and FK9 models with electronic parking brake.
