Overview
The Baer Brakes 4262258FR is an SS4 Plus rear brake system kit with a Fire Red caliper for Ford 8.8 Inch C-Clip rear ends with a 2.5 inch axle standoff. The four-piston floating S4 caliper pairs with a 13 inch two-piece slotted, drilled and zinc plated rotor with a billet aluminum hat, and it suits wheels 17 inch or larger.
Baer built the backing plate to act as the caliper mount while also housing a one-piece park brake shoe assembly. Stainless NAS hardware comes already fitted to the rotors, and DR1-C is the named pad type. The specified rotor thickness is 0.81, and the kit is manufactured in the USA.
Key features

- Hard anodized aluminum pistons, stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- CNC machined from US-sourced forged or billet aluminum
- Powder coated finish
- Stainless braided hoses and NAS stainless hardware included
Floating caliper upkeep
Floating calipers move along their mounting hardware as the pads wear, so the slide surfaces and pins need periodic attention. Dirt, road salt and old grease can cause the caliper to bind, which leads to uneven pad wear and a pull under braking. Clean and relubricate the sliding parts whenever the pads are changed, and make sure the caliper moves freely by hand before reinstalling the wheel.
Slotted and drilled rotors manage heat and wet-weather performance differently from plain rotors, and they usually wear the pad material faster. Park brake hardware also deserves a check during the same service, since cable adjustment and shoe clearance affect how well the parking brake holds. Hoses and fittings should be inspected at the same time because they are easy to overlook on a rear axle.
- Clean slide pins and reapply high-temperature caliper grease
- Check that the caliper slides freely before reinstalling
- Inspect pads for uneven wear and glazing
- Look for scoring, cracks or heat spots on the rotor
- Confirm parking brake shoes adjust and hold after assembly

Vehicle fitment
The rear axle is a Ford 8.8 Inch unit with a 2.5 inch axle standoff. That axle identifies the assembly, not a specific model year or trim.
Compare your wheel with the S135H template before mounting the kit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Wheels must be at least 17.0 inch in diameter for this kit. The park brake shoe assembly comes with the kit, but park brake cables do not, so route the cables before final assembly. Floating calipers and parking brake hardware are best installed by a technician with rear disc experience.
What’s included
The kit contains the S4 caliper, the 13 inch two-piece rotor with billet aluminum hat, the backing plate with park brake shoe assembly, stainless braided hoses, and NAS stainless hardware.
Not included: park brake cables.
