HVCcycle has developed a replacement rear master kit for the RD400 1976-1979
Click Images to Enlarge
The original rear master cylinder on the RD400 will corrode internally causing deep pits. Even with a new rebuild kit the master cylinder with bypass brake fluid and fail to build up pressure to actuate the brake caliper.
Our replacement kit is a bolt on bleed and go. It comes with all the hardware to bolt it  on to the frame.  Includes a banjo bolt micro switch ready to plug into the existing wire harness, and a reservoir hose  
The master cylinder is a Magura unit with a 16mm piston that is found on modern day BMW rear brakes.  It works great with the RD400 brake lever push rod.
The adapter bracket is made from aircraft quality aluminum and anodized black to match the frame.  
Slight Modification of the bracket is needed for use on the RD400F Daytona.
