Motorcycle Brake Calipers

MOTORCYCLE BRAKE CALIPERS AND CALIPER BRACKETS FOR CUSTOM HARLEY BUILDS

Brakes on a custom chopper or rigid frame build require more thought than a stock swap. Most rigid frames and hardtails have no factory brake mount. The caliper, bracket, and anchor rod have to work together as a system, and the master cylinder bore has to match the caliper piston count. This collection covers calipers from Mid-USA, Tokico, Performance Machine, and Kustom Tech, alongside rigid frame caliper brackets from Lowbrow Customs and Mid-USA, and anchor rods for torque reaction control.

BRAKE CALIPERS

• Mid-USA: CNC-machined 6061-T6 billet aluminum calipers in 2-piston and 4-piston versions. Hard anodized aluminum pistons, quad seal design, and brake pad springs to eliminate rattle. Mounting holes are 3.5 inches center-to-center, accepting a 3/8 x 24 banjo bolt. Uses DOT 5 fluid. Available in polished, chrome, and black anodized. Requires a separate caliper bracket. A 3/4-inch bore master cylinder is required for the 4-piston version; 11/16-inch bore for the 2-piston.

• Tokico: Fully remanufactured 4-piston Tokico calipers in left and right side versions. New hardware, new seals, premium brake pads, and the correct metric banjo bolt included. The Tokico name is well-known among builders who ran Japanese-spec calipers on custom builds through the 1990s and 2000s.

• Performance Machine: The Vintage 4-piston 125 X 4R caliper in chrome and black for builders who want a show-quality finish. The Classic 4-piston in black for cleaner custom builds.

• Kustom Tech: SF Super Freni vintage-style 2-piston caliper in black anodized for builders running Kustom Tech hand controls where a matched caliper profile is part of the build direction.

• Cannonball Springbrake: Complete disc brake conversion kits for I-beam and classic springer front ends, in Star Hub and 1978 to 1999 narrow dual flange front hub configurations. A ready-to-install disc brake solution for springer front ends that came with drum brakes.

CALIPER BRACKETS AND ANCHOR RODS

Fitting any of these calipers to a rigid frame or hardtail requires a purpose-built bracket:

• Lowbrow Customs rigid frame brackets: Rear caliper brackets for rigid and hardtail Harley-Davidson motorcycles in 10-inch and 11-1/2-inch rotor configurations, for 3/4-inch and 1-inch axles. Works with Mid-USA, Performance Machine Classic, and any aftermarket caliper with 3.5-inch center-to-center mounting holes. Machined from aluminum in black and raw finish.

• Mid-USA rigid frame brackets: Rear caliper brackets for rigid models with 11-1/2-inch rotors in black, chrome, and polished. Mid-USA also makes a front caliper bracket for springer front end applications.

• Anchor rods: Lowbrow Customs brake caliper anchor rods in 4-inch and 6-inch lengths in black. The anchor rod controls torque reaction at the caliper on rigid frame setups where the caliper bracket has no second point of contact to resist the rotational force generated during braking. The 6-inch version is the most reviewed anchor rod in the collection.

• Specialist brackets: Gigacycle Garage universal 4-piston rear brake brackets and FXR-specific versions. Kustom Tech stainless caliper mounts for springers, swingarm frames, and Showa fork applications.
