Overview
The Baer Brakes 4262238HO is a Hugger Orange SS4 rear brake kit for Ford 8 inch and 9 inch small bearing axle flanges. It combines a fixed 4-piston S4 caliper with a 12 inch one-piece slotted, drilled, zinc-plated rotor, matched to the 5×4.50/5×4.75 bolt pattern.
The backing plate is both the caliper mount and the housing for a one-piece park brake shoe assembly, which brings the parking brake into the same rear unit. Hard anodized aluminum pistons sit in the caliper alongside stainless steel abutments. The 12 inch SS4 is intended for most 16 inch or larger wheels, and the S113E template helps confirm clearance. The aluminum parts are CNC machined from US-sourced forged or billet stock in Phoenix, AZ.
Key features
- Fixed four-piston S4 caliper with a powder-coated Hugger Orange finish.
- Hard anodized aluminum pistons paired with stainless steel abutments.
- Dual seals rated for dust, weather and pressure.
- One-piece slotted, drilled, zinc-plated rotor.
- Noise suppression clips are part of the caliper design.
- Stainless braided hoses that are DOT approved.
Pad wear and rotor condition
Pad life depends on driving, towing and how often the brakes reach high temperatures. Rear brakes often wear more slowly than the front, but a lightly used axle can still develop surface rust on the rotor and glazing on the pads if the vehicle sits for long periods. Regular driving keeps the friction surfaces working as intended.
When pads are changed, rotors should be measured for thickness and checked for cracks, heat spots and scoring. A rotor worn beyond its usable thickness can cause pulsation and reduce braking feel, so inspect it at every pad change. Bedding in new pads gradually helps them transfer an even layer of material to the rotor, which keeps braking smooth from the first stop.
- Bed in new pads gradually before heavy use
- Check the park brake shoe assembly during service
- Use the same pad type on both sides of the axle

Vehicle fitment
The Ford 8 inch/9 inch small bearing axle flange is the sizing point to match, along with the 5×4.50/5×4.75 bolt pattern. Confirm your vehicle’s year, model and trim before ordering.
Axle flanges outside the listed Ford 8 inch and 9 inch small bearing style are not covered by this kit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The park brake cables are not included, so the built-in park brake shoe assembly needs cables from another source. Measure clearance between the 16 inch minimum wheel and the S4 caliper using the template. Brake work is safest left to a qualified installer.
What’s included
One 12 inch rotor, the S4 caliper, the backing plate with one-piece park brake shoe assembly, and stainless braided hoses.
Not included: park brake cables.
