Hawg Halters Disc Brake Caliper

Hawg Halters Disc Brake Calipers: Performance Engineered for V-Twin Riders

When it comes to stopping power on custom Harley-Davidson builds, baggers, and big wheel conversions, few names carry as much weight as Hawg Halters (HHI). The company has earned a well-deserved reputation as an innovator in motorcycle disc brake technology, and their lineup of disc brake calipers stands as the centerpiece of that legacy. Whether you're upgrading a stock touring bike or outfitting a full custom bagger, HHI calipers are engineered to deliver measurable improvements in feel, modulation, and outright braking performance.

A Full Range of 4 & 6 Piston Caliper Designs

Hawg Halters offers one of the most comprehensive caliper selections in the V-twin aftermarket. 4 and 6 piston axial brake calipers as well as 6 piston radial brake caliper kits are available for Harley-Davidson and Indian motorcycles, covering everything from single disc to dual disc front setups and dedicated rear caliper kits. Rotor compatibility spans 11.5", 11.8", 13", and even 18" rotors, making HHI one of the few brands equipped to support both stock-diameter and large-rotor big wheel builds.

The 500 series differential bore 4 piston caliper represents a notable engineering achievement in the lineup. It features a smaller diameter piston at the lead-in side of the rotor and a larger piston on the trailing side — a design that promotes more even pad wear and progressive bite. A dual piston seal system provides each piston with two layers of protection: a wiper seal guards the main pressure seal against contamination, extending service life and maintaining a leak-free operation, while also improving piston pullback to reduce brake pad drag on the rotor.

CNC-Machined Billet Aluminum Construction

Every HHI caliper is precision CNC-machined from billet aluminum, keeping weight down while delivering structural rigidity that exceeds OEM standards. Stainless steel pistons and chrome hardware are standard, and each caliper features a quick-change design for easy brake pad maintenance without pulling the wheel. Dual hidden bleeders simplify bleeding and help eliminate air pockets quickly. Billet aluminum adapter brackets are included where required, making installation clean and straightforward.

Coverage Across Popular Harley-Davidson Platforms

HHI calipers are engineered as true direct bolt-on upgrades across a wide range of platforms. Coverage includes Harley-Davidson Touring models (2008–present), Softail (including M8), Dyna, FXR, Sportster, Trike, and V-Rod, as well as select Indian and Victory motorcycles. Rear caliper kits cover FX/FL, FXR, and Softail platforms as well. This breadth of fitment means riders can source a matched front and rear braking solution from a single trusted manufacturer.

Finish Options to Match Any Custom Build

Beyond performance, HHI calipers are designed with aesthetics in mind. Available finishes include Chrome, Black, Polished, Blaze Red, Aztec Red, Inca Gold, and Cobalt Blue — a palette wide enough to complement virtually any paint or wheel scheme. Radial calipers are also delivered in Machine and Show Chrome. Calipers ship complete with brake pads, mounting hardware, banjo bolts, and crush washers so riders can get straight to the build. All Hawg Halters calipers are made in the USA.
