    Honda Goldwing Secondary Master Cylinder Recall

    NHTSA recall Number: 15V-700

    December 22nd, 2015

     

    PREFACE

                 Hannigan Motorsports would like to inform our customers of the Honda Recall NHTSA Number 15V-700 and how it relates to their Hannigan Motorsports Trike conversion. If you have a Hannigan Sidecar Rig and are worried if you are affected by the recall, the answer is a definite YES, as your Secondary Master Cylinder (SMC) is still functioning as it was designed by Honda and needs to be inspected. If you are a Trike owner, please continue reading below.

     

    THE RECALL AND YOUR TRIKE

                  The Hannigan Trike conversion process as it relates to the Goldwing braking system is as follows. Hannigan Motorsports leaves the Secondary Master Cylinder (SMC) in OEM location on the bike for the conversion. The SMC is then capped off on the metal line that previously went to the rear caliper. This capped line is located on the rear swingarm assembly and can be seen by removing the right side panel of the motorcycle. The functionality of the SMC has been removed from the braking system of the bike during the conversion process to a trike. This results in fluid still in the SMC lines but ensures no fluid flow through the unit. The SMC does not interfere with the braking setup of the bike (front or rear brake) after a Goldwing has been converted to a Hannigan Trike.

     

    TRIKE CONVERSION BRAKING SETUP

                  Brake controls and how they function after a conversion to a Hannigan Trike differ slightly after a conversion. When the front brakes are applied via the front brake lever, the brake system pivots the left front caliper upward activating the SMC which transitions braking power to the rear wheel as well. In the case of a Hannigan Goldwing Trike Conversion, the front brake lever no longer will trigger the SMC function resulting in only front brakes being applied via the front brake lever. In regards to the rear brake foot pedal, when the pedal is depressed, the linked braking system on the bike will proportion the brake pressure between the front and rear calipers resulting in balanced brake application. This function of the rear brake pedal assembly does not pass through the SMC after your conversion.

     

    WHAT TO DO

    How does this relate to your Hannigan Trike and the recall? Simply put it is Hannigan Motorsports’ request that owners of our trike conversions still respond to Honda’s recall and have their motorcycles inspected by a certified Honda Dealer. This is to ensure that Honda has inspected the braking system and will result in them marking the VIN number on the motorcycle to show it has been thoroughly checked with regards to the recall.

     

    DEALER INFORMATION

    When taking your conversion to a dealer, they might inquire as to the proper brake bleeding procedure on the Hannigan Trike Conversion. The steps required to thoroughly bleed the system are listed below.

    1. left caliper upper bleed port
    2. Right caliper lower bleed port
    3. Rear caliper lower bleed port (trike brakes)
    4. Rear caliper upper bleed port (line that is capped off on trikes)
    5. Secondary Master Cylinder (SMC) port on left fork leg

     

    Location of the rear brake master cylinder is under the right side chrome cover above the driver foot rest. Keep the reservoir full when bleeding. Failure to do so will allow air to enter the master cylinder.

     

     

    IN CLOSING

    Hannigan Motorsports would like to say thank you to our customers and dealer network for their continued support to the industry and wish you many happy miles in the future.
