Motorcycle Brake Caliper Brackets

MOTORCYCLE BRAKE CALIPER BRACKETS AND ANCHOR RODS FOR CUSTOM AND RIGID FRAME BUILDS

Running disc brakes on a rigid or hardtail motorcycle means the frame has no factory caliper mount. The bracket positions the caliper over the rotor, and the anchor rod keeps the caliper from rotating with the wheel under braking. Both are required for a functional rear disc brake setup on any custom frame. This collection covers rear caliper brackets for rigid and hardtail builds, front caliper mounts for springer and swingarm front ends, and Lowbrow Customs anchor rods in 4 and 6-inch lengths.

REAR CALIPER BRACKETS

Lowbrow Customs makes USA-made aluminum rear caliper brackets for rigid and hardtail Harley-Davidson motorcycles:

• 11-1/2-inch rotor, 3/4-inch axle: Available in raw, black, and mounted as a set with the included axle spacer. Works with any caliper with 3.5-inch center-to-center mounting holes, including Mid-USA, Performance Machine Classic, and most aftermarket 4-piston units. The caliper bolts to the bracket; hardware is builder-supplied.

• 11-1/2-inch rotor, 1-inch axle: For rigid frame builds running a 1-inch axle rather than the standard 3/4-inch.

• 10-inch rotor, 3/4-inch axle: For builds where the rotor diameter is 10 inches rather than the more common 11-1/2-inch setup.

All Lowbrow Customs brackets are 0.40-inch thick aluminum and made in the USA.

Mid-USA makes the same 11-1/2-inch rigid frame caliper bracket in chrome, black, and polished finishes for builders who want a matched finish to the Mid-USA caliper. Unity Manufacturing covers swingarm Harleys with a raw aluminum 11.5-inch bracket for 3/4-inch axle applications where the stock swingarm has no caliper provision.

Gigacycle Garage covers more application-specific needs: a bracket for rigid frames and 1982 to 2003 Harley-Davidson Sportsters, a universal swingarm bracket for 3/4-inch axle applications, and a bracket specific to 1982 to 1994 and 1999 to 2000 FXR models.

FRONT CALIPER BRACKETS

• Springer front ends: Mid-USA front caliper bracket for springer models in chrome, and Kustom Tech SF stainless caliper mounts for springers. The Kustom Tech mount pairs with the SF Super Freni caliper line for complete matched front brake setups.

• Swingarm and Showa forks: Kustom Tech SF stainless mounts for swingarm frames and Showa fork tubes for builders running non-stock front brake setups on later Harley-Davidson platforms.

• Dual caliper setup: The Speed Merchant radial front brake dual caliper mounts in black for 2000 to 2021 Harley-Davidson for builders who want a dual front caliper setup on a performance-oriented custom.

BRAKE ANCHOR RODS

The anchor rod is what prevents the caliper from rotating with the rotor when the brake is applied. Without it, the bracket and caliper assembly will try to spin under braking load. Lowbrow Customs makes anchor rods in 4 and 6-inch lengths in black and chrome:

• 6-inch: Adjustable from 6 to 7-1/2 inches via heim joints that offer 3/4-inch of adjustment each. Heim joint ID is 3/8-inch. Body is 5/8-inch diameter steel, milled in the center so jam nuts can be tightened with a 1/2-inch wrench. 14 reviews on the black version. Can also be used for front caliper anchor applications on custom builds.

• 4-inch: Same construction, shorter overall length for tighter frame geometries where the 6-inch rod is too long to reach from the caliper bracket to the nearest solid frame member.
