Overview
Fire Red is the caliper finish on this Baer Brakes 4262259FR SS4 rear brake kit, made for Ford 9 inch early big bearing rear axle flanges. It pairs a four-piston S4 caliper with a 12-inch one-piece slotted, drilled rotor finished in zinc plate, and it has five lugs on a 5×4.50/5×4.75 bolt pattern.
Baer’s backing plate is where the caliper mounts, and it houses a one-piece park brake shoe assembly for the parking brake. Braided hoses are included in the package. Because the minimum wheel diameter is 16.0 inch, Baer advises checking the S113E template against the wheel you plan to run.
Key features
- Fire Red S4 four-piston caliper with powder coated finish
- 12-inch one-piece slotted, drilled, zinc-plated rotor
- CNC machined caliper components from US-sourced forged or billet aluminum
- Hard anodized aluminum pistons, stainless abutments and noise suppression clips
- Dual seals rated for dust, weather and pressure
- Park brake shoe assembly and braided hoses in the package
Caliper finish and care
Powder coat on a caliper protects the metal from road grime and brake dust, but it can chip where stones or tools strike it. Clean the caliper with mild soap and water rather than harsh solvents, and wipe away brake dust regularly so it does not bake onto the finish. Avoid aiming high-pressure spray directly at the seals.
Care also covers the rest of the rear setup. Inspect the dust and pressure seals when the pads are changed, look for fluid seepage at the fittings, and check that the rotor’s zinc plate is not flaking from heat cycles. When a cabled parking brake is added, make sure the routing keeps the finish away from exhaust heat and road debris.
- Clean with mild soap and water
- Avoid high-pressure spray on the seals
- Address small chips early to limit corrosion
- Check seals and fittings at each pad change

Vehicle fitment
It is designed for Ford 9 inch early big bearing axle flanges, so review the axle type and S113E template against your rear end before buying.
Fitment is not tied to a named vehicle here, so confirm axle compatibility yourself. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Measure your wheel against the S113E template and the 16.0-inch minimum diameter before mounting the kit. Park brake cables are not supplied, so a cabled parking brake will require cables sourced elsewhere.
What’s included
The S4 caliper, the one-piece 12-inch rotor, the backing plate with its park brake shoe assembly, and braided hoses.
Not included: Park brake cables.
