Rear brake caliper mounting bracket
An interesting design of a rear brake caliper mount for a 1985 Harris F1 race bike that we retro fitted a rear modern 17" wheel. We needed to mount the original Triumph brake caliper onto the new brake disk diameter. Also part of the design was to keep the same brake system (ie the brake torque arm was connected to the frame via rose joints, and so the caliper bracket had to rotate on the rear axle as the suspension moved).
