Overview
The Baer Brakes SS4 brake kit, part number 4262261FR, is a rear disc brake package with a 4-piston S4 caliper in Fire Red and a 12.0 Inch one-piece slotted, drilled and zinc-plated rotor. It is made for Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern.
The park brake shoe assembly is part of Baer’s backing plate, which also acts as the caliper mount. The rotor is rated for a 16.0 Inch minimum wheel diameter, so it suits wheels 16 inches or larger. The kit uses the S113E template for wheel comparison.
Key features
- Two-piece, 4-piston S4 caliper manufactured in Phoenix, Az
- Caliper body CNC machined from US-sourced forged or billet aluminum
- Powder coated finish
- Hard anodized aluminum pistons, stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- One-piece slotted, drilled and zinc-plated rotor
Hose and fluid checks
Braided hoses hold up well to flex and heat, but the braid can still abrade against suspension parts or frame edges. Route each hose so it does not rub or pull tight when the axle moves, and check the fittings for seepage. A soft pedal or fluid residue at a fitting usually points to the hose or its connection rather than the caliper.
Brake fluid absorbs moisture from the air over time, which lowers its boiling point and can affect braking under heavy use. Replacing fluid on a regular schedule and after any bleeding keeps the system responsive. Use fresh fluid of the type your master cylinder requires.
- Check hoses for chafing at each service
- Keep fluid in a sealed container
- Bleed the system after any hose change

Vehicle fitment
The axle sets fit here: Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern, requiring wheels with at least a 16.0 Inch minimum diameter.
Fire Red is the caliper color and has no bearing on fit. Compare the S113E template with your wheel and check the flange on your housing. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Braided hoses and hardware are included, and the rotor comes with the backing plate. Park brake cables are not part of the kit, so plan to source them separately. Measure wheel clearance with the S113E template first, keeping the 16.0 Inch minimum in mind. A qualified technician should install and bleed this brake system.
What’s included
The kit includes the S4 caliper, the one-piece rotor, the backing plate with park brake shoe assembly, and braided brake hoses with hardware.
Not included: park brake cables.
