The customer was not happy with the performance of the boss mounted v-brake and wanted a conversion made for a caliper brake.
A prototype conversion plate was made from acrylic to test the principal and produce the design. The prototype highlighted an acute bend in the brake cable. The brake was repositioned to remedy this an ensure a smooth action.
The plate was CNC cut from 4mm thick carbon fibre sheet.
The caliper brake is bolted to the conversion plate and then the plate bolts to the frame using the old brake boss mounts.
A new carbon aero shrowd was made to conceal the brake set up.
The shrowd was made from a combination of unilateral carbon and bi-lateral 3k.
The shrowd held itself inplace by clipping round the mounting plate then. After that only one bolt was needed to anchor it in place.
