Overview
The Baer Brakes 4262259HO is an SS4 rear brake kit in Hugger Orange, 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 and zinc-plated rotor, and the 5×4.50/5×4.75 bolt pattern makes it a five-lug kit.
The backing plate holds the caliper and carries a one-piece park brake shoe assembly, so the parking brake function comes with the kit. Braided hoses are included. The minimum wheel diameter is 16.0 inch, which matters when choosing a wheel for the 12-inch rotor.
Key features
- Hugger Orange powder coated S4 caliper, manufactured in Phoenix, Az
- 12-inch one-piece rotor, slotted, drilled and zinc plated
- Hard anodized aluminum pistons with stainless steel abutments
- Dual dust, weather and pressure seals
- Park brake shoe assembly housed in the backing plate
- Braided hoses included; hose material steel braided
Pads, hoses and bleeding
Braided hoses are often chosen for a firmer pedal feel, but they need careful routing. Keep them clear of exhaust heat, tie-rod ends and suspension travel, and allow enough slack for the axle to rise and fall. A hose that is kinked or rubbing will wear through, so route it once with the wheels off and check it again after the first off-road trip.
Bleeding follows any hose change or caliper work. Start at the caliper farthest from the master cylinder, use fresh fluid, and keep the reservoir topped up so air does not return. Pad bedding is a separate step: make a few moderate stops before loading the brakes for a longer run.
- Use fresh fluid when filling the system
- Keep hoses clear of heat and moving parts
- Bed new pads with moderate stops
- Recheck hose clearance after the first trail trip

Vehicle fitment
Its design centers on Ford 9 inch early big bearing axle flanges. Verify the axle type and the S113E template against your rear end before buying.
Baer cannot guarantee that the kit suits every wheel style, so compare the template with the wheel you intend to run. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Measure the wheel against the S113E template before mounting, since the 12-inch rotor needs a wheel 16 inches or larger. Park brake cables are not part of the package, so the parking brake connection needs cables from another source.
What’s included
The S4 caliper, the one-piece 12-inch rotor, the backing plate with its park brake shoe assembly, and braided hoses with hardware.
Not included: Park brake cables.
