TC Bros. Pro Series Radial Caliper Conversion (Brake Bracket and Line) Kit for 2018-Up Harley-Davidson M8 Softail

    • Sophisticated machining offers an elegant solution to brake plumbing trickiness

    • Makes the "jump" from the bracket to the caliper for a slick, custom-appearing install

  • Caliper bleeding shim is included to make bleeding a snap

Radial caliper swaps are a common and usually a reasonably simple upgrade. However, certain Harley-Davidson Softail models can make the job labor-intensive because replacement of the brake line requires significant disassembly of the motorcycle to access the brake line that runs to the ABS modulator (EHCU).

Make the job simple with this unique kit available only from TC Bros. It permits reuse of your OEM brake line, which you'll use to send fluid into the bracket itself. This kit contains a jumper line specifically made to allow fitment of a Brembo radial-mount caliper (available separately).

The bracket kit includes all required fasteners, crush washers, and the appropriate banjo bolts to turn a massive hydraulic headache into a quick swap-and-bleed job. We're proud to make these kits in the USA, and pleased to offer this labor-saving solution to make your swap a bit more approachable.
