Ford 9" Weld On Disc Brake Conversion Kit, 3.0" Axle Tube
Ford 9" Weld-On Disc Brake Kit (3.0" Axle Tube)
A complete weld-on disc brake conversion for 3" Ford 9" axle tubes — no guessing, no missing parts.
This kit gives you everything you need to swap out heavy, outdated drum brakes for a modern disc setup. Designed for Ford 9" axles with 3.0" tubes, it includes weld-on brackets, Ford 5-lug rotors (from an ’89 Bronco), calipers, pads, hoses, and even the small parts like line clips and tabs. It's a straightforward weld-on setup, chosen because Ford used multiple backing plate flange patterns over the years — this keeps it universal and reliable.
Disc brakes improve stopping performance, reduce weight, and are far easier to service than drums. This setup works with 15" steel wheels with a max 4" backspacing or larger aluminum wheels. For slip-over rotors, you may need to machine the axle flange. Be sure to re-bleed your brakes and check if you need to remove any residual valves. A proportioning valve is strongly recommended to dial in proper front/rear brake bias.
Key Features
- Parts Number: R2046
- Fits Ford 9" axles with 3.0" axle tubes
- Includes weld-on brackets, rotors, calipers, pads, hoses, and hardware
- Uses 5x5.5" rotors from ’89 Ford Bronco
- Banjo-bolt hydraulic hoses accept 3/8"-24 inverted flare hard lines
- Improves braking performance and reduces weight vs drum brakes
Kit Includes
- 2 weld-on disc brake brackets (3" ID)
- 2 Ford 5x5.5" bolt pattern rotors
- 2 brake calipers
- 4 new brake pads
- 2 hydraulic hoses with banjo fittings
- 2 weld-on brake line tabs
- 2 brake line clips
Note
Requires single steel wheel 15" with a maximum of 4" backspacing, or larger aluminum wheels. For slip-over rotors, axle shaft flange may need to be machined. Re-bleed the system after install. If your vehicle has a residual valve (internal or external), it should be removed to prevent rear brake drag. An adjustable proportioning valve is recommended to set proper front/rear brake bias — front brakes should do ~70% of the work.
