Sterling Axle Disc Brake Conversion Kit

Sterling SRW Axle Disc Brake Kit

Complete disc brake conversion for Ford Sterling single rear wheel axles (1984–1997).

This kit converts older-style Sterling full float SRW axles from drums to discs, improving braking performance, reducing weight, and simplifying maintenance. Designed for Sterling axles found in 3/4- and 1-ton Ford trucks (1984–1997) with the standard 8x6.5 lug pattern, it replaces outdated drum brakes with rotors, calipers, pads, and all necessary hardware. The brackets are designed to work with stock housings, with included spacers for variations between 3/4- and 1-ton applications.

Compatible with single rear wheel full-float axles only, this kit will not work with semi-float, dually, or metric lug pattern Sterlings. Installation requires 16" steel wheels with ≤4" backspacing or larger aluminum wheels. Rotors slip over the hub for easy service. Proper brake bleeding, a proportioning valve, and removal of any residual valve are recommended for correct brake balance and performance.

Note

Fits 1984–1997 Ford SRW Sterling full-float axles only. Requires single 16" steel wheels (≤4" backspacing) or larger aluminum wheels. Some housings require spacers (included). Rotor slips over hub. Re-bleed brakes after installation. Use a proportioning valve to balance bias (front axle should carry ~70% of braking). Remove any residual valve to prevent dragging or lockup.
