If you are looking for significantly more stopping power, you should consider replacing your classic drum brake system with a disc brake.
After extensive 3D simulations on the computer and countless test kilometers on any terrain, we can now rightly claim that this brake meets our high requirements.
This kit developed by Cannonball converts Harley-Davidson models with Big Twin, Servi-car or WLC Springer forks from drum brake to disc brake.
Each kit includes a:
- dual piston caliper with pads,
- caliper bracket,
- 10” disc rotor,
- brake anchor,
- wheel hub adapter, and all small parts necessary for final assembly.
Brake lines and handlebar master cylinder are not included and must be ordered separately.
Kits that are delivered without axle reuse the OEM axle (please see article details).
CB SpringBrake Patent
Under protection of patent 10 2022 114 505.0.
Use with Ø12 mm master cylinders! Brake lines attach with 3/8” mm banjos.
If brake pads need to be replaced, it is mandatory to use WW 27-659 due to special dimensions.
1.) The pivot point of the brake shackle on the backing plate or caliper bracket must not be positioned vertically above or in front of the wheel axle (driving direction). In this case the moving forces in your fork parallelogram will be reversed and the fork will rebound instead of being compressed when you apply the brake. This will generate very high forces to impact on your rigid fork leg with possible damage.
2.) Caliper bracket or drum brake backing plate must float on the wheel axle. If not, the fork will rebound as well when applying the brake. Result: see above.
