GM 14-Bolt Weld-On Disc Brake Conversion Brackets (Pair)
F021010
The Crane Axle GM 14-Bolt Weld-On Disc Brake Brackets provide the mounting foundation for converting a GM 14-Bolt full-float rear axle from factory drum brakes to a GM 3/4-ton disc brake setup. Made from 3/8" steel, the brackets are designed to weld directly to compatible 3.5" axle tubes and position the calipers around common GM 3/4-ton brake components.
The weld-on design gives fabricators control over final caliper position and works well for factory 14-Bolt housings, axle swaps, and custom off-road axle builds. Converting to disc brakes can remove much of the weight and complexity of the original drum assemblies while simplifying wheel-end service on trail rigs, rock crawlers, tow rigs, and custom 4x4 builds.
Includes:
- (2) 3/8" Weld-On Disc Brake Caliper Brackets

Fitment
Designed For:
- GM 14-Bolt full-float rear axles
- 3.5" axle tubes
- GM 3/4-ton disc brake conversions
- Factory 14-Bolt housing rebuilds
- Custom 14-Bolt axle builds and swaps
- Rock crawlers, trail rigs, tow rigs, and custom 4x4s
Fitment Notes:
- Does not fit GM 14-Bolt semi-float axle applications.
- Verify the axle has 3.5" diameter tubes before ordering.
- Rotor, caliper, hub, and wheel-end configuration must be checked together before final welding.
- Vehicle year, make, and model alone do not guarantee fitment because 14-Bolt axles are commonly swapped between vehicles.
- Test-fit the complete brake assembly and establish caliper position before welding the brackets permanently to the housing.
FAQ
What axle do these disc brake brackets fit?
These brackets are designed for GM 14-Bolt full-float rear axles with 3.5" axle tubes. They are not intended for 14-Bolt semi-float axle applications.
What brakes are these brackets designed to use?
The brackets are designed around compatible GM 3/4-ton disc brake calipers and rotors. Verify the complete rotor, hub, and caliper configuration before final installation.
Why use weld-on brake brackets instead of bolt-on brackets?
The weld-on design lets the fabricator establish the caliper position around the actual hub and rotor assembly. Once alignment and clearance are confirmed, the brackets are permanently welded to the axle housing.
How should the brackets be positioned before welding?
Mock up the hubs, rotors, calipers, and pads before final welding. Center the caliper over the rotor and verify clearance for the caliper body, bleeder, brake hose, wheel, and surrounding suspension components.
Does this conversion retain a parking brake?
These brackets do not provide a parking brake system by themselves. Parking brake function depends on the calipers and supporting components selected for the complete brake system.
