Springer Drum to Disc Brake Conversion

Cannonball SpringBrake Kits for Classic Springer Forks

Damn! Rolled past the bar again!
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 by Cannonball converts Big Twin, Servi-car, 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, 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 (pls see article details).

Replace drum brakes in Springer forks with disc brakes.

The deceleration values of the front original brakes of Harley-Davidson motorcycles with Springer forks are not really impressive. For those who want significantly more stopping power here, there are conversion kits from Cannonball or Samwel that can be used to convert your bike from drum brakes to disc brakes. The Cannonball kits in particular show that a Springer fork can cope with an 11.5" brake disc if the components are correctly designed. And we know from experience that the deceleration values of disc brakes increase with the disc diameter.
