Overview
The Baer Brakes 4262256CY is a complete SS4 rear disc brake kit for Ford 8.8 inch C-clip rear ends with a 2.5 inch axle standoff. It combines a 4-piston S4 caliper with a 12 inch, 1-piece slotted, drilled and zinc plated rotor, so it suits owners who want more rear stopping power on an off-road or performance build.
The kit is laid out for a 4×4.25 wheel bolt pattern with 4 lug nuts. Baer’s backing plate serves as the caliper mount and also houses a modern 1-piece park brake shoe assembly, which keeps the parking brake inside the same package. The caliper takes the popular DR1 or HB100 pad type, and stainless braided hoses are included.
Key features

- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- 12 inch 1-piece slotted, drilled, zinc plated, vented rotor
- Integrated 1-piece park brake shoe assembly in the backing plate
- Stainless braided, DOT approved brake hoses included
Spotting rear brake wear
Rear brakes often wear more slowly than the fronts, but a performance build with added weight or frequent hard stops speeds that up. Pad friction material should be checked at every wheel removal, and pads that are down to a thin layer or have a squeal from the wear indicator should be replaced. Rotors need attention when they show deep scoring, heat cracks, or a thickness near the minimum cast into the hat.
Pulsation through the pedal and a pull to one side under braking are common signs of uneven rotor wear or a sticking caliper slide. A caliper that drags can heat the rotor and cause a burnt smell after a drive. Checking that the caliper pins move freely during a brake job helps prevent uneven pad wear on both sides.
- Look for scoring or blue heat spots on the rotor face
- Check the pads for even thickness across both sides
- Feel the wheel hub after a drive for uneven heat

Vehicle fitment
The kit is built for Ford 8.8 inch C-clip rear ends with a 2.5 inch axle standoff. Check the axle flange, the 4×4.25 bolt pattern and the 16 inch minimum wheel diameter against your axle and wheels.
This kit is named for 8.8 inch C-clip rear ends only, so do not assume it fits other rear axle flanges. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The park brake shoe assembly is part of the backing plate, so plan the rear brake install around that layout. The kit includes stainless braided hoses, but park brake cables are not included. Wheel styles vary, so use the S113E template to compare the rotor and caliper against your wheel before mounting. Support the vehicle on jack stands and never work under a vehicle held only by a jack.
What’s included
The kit includes the S4 caliper, the 12 inch 1-piece rotor, the backing plate with its park brake shoe assembly and stainless braided hoses.
Not included: park brake cables.
