The quintessential classic-disc upgrade: original Baer 2-piston pad-guided calipers (red, D412 pads) over 11" one-piece slotted, drilled, zinc-plated rotors with integral hubs. Comes complete with premium bearings (races installed), dust caps, brackets, stainless braided hoses, and hardware. Fits select 15"+ wheels. Use a 15/16" master (or 7/8" for manual); larger bores reduce line pressure and increase pedal effort.
