Blue Print outlines a common issue with rear brake hoses and rear brake pads.
Rear Brake Pad Set
This relates to part number ADB112101, which fits Honda Civic FC1, FC9, FC8, FK6, FK7, FK8, and FK9 models with electronic parking brake.
PROBLEM
Rear brake failure after replacement of the rear brake pads, or any other repair work involving removal of the rear brake caliper, resulting in the following. 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. Please note, if the brake caliper piston is found to be over-extended, replace the caliper. Damage to the wiring harness or connector.
CAUSE
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.
SOLUTION
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.
Rear Brake Hose
This relates to part ADC45357, which fits Mitsubishi Colt (VI) 2004-2013, SMART Forfour I (454) 2003-2008.
PROBLEM
After applying the parking brake the rear brake caliper becomes seized in operation, which could take 5-10 minutes to move freely again. This problem can affect either side separately or both sides together.
CAUSE
The rear caliper brake hose swells internally, causing a partial blockage. This restricts the flow of brake fluid to the brake caliper, subsequently making the brake operation intermittent.
SOLUTION
Upon inspection, the seized brake caliper will immediately become free in operation when the bleed nipple is released. As a result, the rear brake caliper, brake pads and handbrake mechanism should now be moving freely. Replace with a new brake hose (or hoses) and bleed the brake system using a suitable DOT 4 brake fluid. This should be followed by an operational test of the brake system to check that it is now functioning correctly.
