Spring Brake Kits for Classic Springer Forks
Of classic springer forks (originals and authentic replicas), German 'old-timer' parts and accessory specialist W&W Cycles (Wuerzburg) says that "if you are looking for significantly more stopping power, you should consider replacing the original or original style classic drum brake system with a disc brake.
"After extensive 3D computer simulations and countless test kilometers on all kinds of terrain, we are now able to offer a brake kit that meets our high requirements."
This kit by Cannonball converts Star Hub Big Twins (1930-1949), Servi-car (1941-1958), WLC or I-Beam Springer forks from drum brake to disc brake. Each kit includes a dual piston caliper with pads, caliper bracket, 10" disc rotor, brake anchor, star hub adapter, and all small parts necessary for final assembly. The star hub wheel axle can be reused.
The replacement brake lines, and handlebar master cylinder are not included and must be ordered separately - use with 12 mm master cylinders; the brake lines attach with 3/8" mm banjos. If the brake pads need to be replaced, the special dimensions and geometry mean it is necessary to use WW 27-659.
This 10" steel/aluminum and parkerized rotor fits 17.5 mm axle diameters and takes DOT 4 or 5 brake fluid.
