Overview
Part 4262773FR is Baer’s SS4 11.0-inch rear disc brake system in Fire Red, offered for Ford 9 Inch Torino (late big) bearing housing ends. It combines an S4TL four-piston caliper with an 11-inch one-piece rotor that is slotted, drilled and zinc plated.
A park brake assembly sits inside the backing plate, which Baer designed to act as the caliper mount while keeping the wheel-side package compact. The rotor is vented, and the kit lists 5 lugs on a 5×4.50/5×4.75 pattern with a minimum 15.0-inch wheel diameter.
Key features
- Top-loaded S4TL caliper with four pistons, assembled in Phoenix, Arizona
- CNC-machined from forged or billet aluminum sourced in the United States
- Fire Red powder coat finish
- Hard-anodized pistons, stainless abutments and noise suppression clips
- Dust, weather and pressure seals with a banjo inlet that has no pipe threads
- One-piece slotted, drilled and zinc-plated 11-inch rotor
- Park brake assembly within the backing plate
- Steel braided hoses, DOT approved, with stainless hardware included
Wheel clearance and setup
Wheel clearance decides whether a rear disc kit goes on cleanly. Offset, backspacing and tire width all change how close the rotor and caliper sit to the inner wheel face. Hold the template against the wheel and turn it through a full rotation, watching for contact at the caliper body and the park brake hardware.
Tires with larger sidewalls or a taller footprint can also change clearance, so consider tire size when choosing a wheel. Spacers reduce clearance further and are best avoided with a caliper this close to the wheel. Once the wheel is mounted, recheck clearance after the first few trail runs, since suspension travel can shift it.
Bleed the hydraulic system only after the lines are routed clear of moving parts. Keep the wheel bolts torqued to the value in the vehicle service manual and check them after the first drive.

Vehicle fitment
Match your rear axle housing ends to the Ford 9 Inch Torino (late big) bearing axle flanges the kit is built for before buying. Confirm fit for your vehicle’s year, model and trim before ordering.
Fit to every wheel style cannot be assured by Baer, so lay the ST217A template against the wheel before ordering.
Installation notes
The park brake cables are not in the box, so the park brake will need its own cable set. Use the ST217A template to check wheel clearance before the wheel is mounted. A qualified technician should complete the rear disc install and the hydraulic bleed.
What’s included
The kit includes the S4TL caliper, the 11-inch rotor, the backing plate with park brake assembly, and steel braided hoses with hardware.
Not included: park brake cables.
