Cannonball SpringBrake Conversion Kits to Disc Brake for 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 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 (pls see article details).

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.

These articles can be used with either DOT4 or DOT5 brake fluid. However, DOT4 and DOT5 must not mixed, due to being chemically not compatible. One should always stay with the same brake fluid type.

  • steel / aluminum, parkerized, brake rotor Ø: 10”
  • required brake fluid: DOT 4 or 5
