Overview
The Comp Yellow version of Baer’s SS4 11-inch rear brake system carries part number 4262773CY. It is a rear disc kit with an S4TL four-piston caliper, an 11-inch one-piece rotor and a park brake assembly, designed for Ford 9 Inch Torino (late big) bearing housing ends.
The backing plate serves as both the caliper mount and the housing for the compact park brake, a layout that supports wheel fitment. The caliper is finished in Comp Yellow over a powder-coated surface, and the wheel bolt pattern is 5×4.50/5×4.75 with 5 lugs.

- Dual dust, weather and pressure seals with a banjo inlet that has no pipe threads
- Slotted, drilled, zinc-plated one-piece 11-inch rotor
- Park brake assembly integrated into the backing plate
- Braided stainless hoses and hardware are part of the kit
Choosing the right setup
Rear disc systems are judged by how well the caliper, rotor and backing plate work together under load. A slotted, drilled rotor sheds heat and water differently from a plain one, so match the rotor to how the vehicle is used, whether that is street driving, trail work or mixed use. Keep the caliper and pad combination in mind when you choose a rotor, since pad material affects bite and wear.
Care comes down to regular inspection. Check pad thickness, rotor surface and the braided hoses for chafing or leaks, and make sure the park brake cable stays free of corrosion and stretch. Hardware that loosens over time should be retightened and rechecked after the first few drives, and fluid should be replaced on the schedule the vehicle manufacturer or a qualified shop recommends.
- Match the rotor to your driving conditions
- Inspect pads, hoses and cables on a regular schedule
- Replace worn pads and rotors before they reach the minimum thickness

Vehicle fitment
It is designed for rear axles with the Ford 9 Inch Torino (late big) bearing axle flange. Confirm fit for your vehicle’s year, model and trim before ordering.
Wheel fit cannot be guaranteed for every wheel style. Run the ST217A template against your wheel before ordering.
Installation notes
The park brake needs cables, and none are included with this kit. Braided steel hoses come with the hardware. Hold the template against the wheel before final mounting, and let a shop experienced with rear disc systems complete the work, since park brake and line routing matter.
What’s included
The kit includes the S4TL caliper, the 11-inch rotor, the backing plate with park brake assembly, and braided hoses with hardware.
Not included: park brake cables.
