Hawg Halters 4-Piston Front Brake Caliper — Stock-Size Rotor (500 Series)

HHI's 500-series direct bolt-on front caliper: a four-piston differential-bore design machined from 6061 billet aluminum, with a smaller piston at the rotor's lead-in and a larger one on the trailing side to equalize heat across the pad for optimum friction and lever feel. The dual-piston seal system adds a wiper seal that protects the main pressure seal and improves piston pullback to reduce pad drag. For Touring riders, select '2008-23 FLH and 2006-up V Rod' for 2014–2023 bikes, or '2000-07 FLH' for earlier FLH models. Sold individually — pick your side.

FITMENT

Direct bolt-on for 1984-up Harley-Davidson models except the Springer (per HHI). Touring applications in the options: 2000-07 FLH and 2008-23 FLH — HHI's FLH coverage for this caliper ends at 2023, so no 2024-up application is published. Excluded (per HHI): 1984-99 narrow-glide models with wire wheels (that year option is listed separately in the configurator).

INSTALLATION

Brake work is safety-critical — Hawg Halters states its brake systems should be installed by a qualified service technician only. Follow HHI's published 4 & 6 piston caliper installation instructions (HHI Caliper Installation Instructions, 2000-up (PDF)) and your Harley-Davidson service manual for mounting torque and brake bleeding. No official HHI install video exists for this caliper — installation is manual-only.

QUESTIONS RIDERS ASK

Which year option fits my 2014–2023 Touring bike?
Select '2008-23 FLH and 2006-up V Rod' — that's HHI's option covering 2008–2023 FLH Touring models.

Does it fit my 2024-up Touring bike?
HHI publishes this caliper's FLH coverage through 2023 and does not list a 2024-up application, so we can't confirm it for 2024-up bikes.

Is this one caliper or a pair?
One caliper, in the side you select. Dual-disc bikes need a Left and a Right.
