Overview
The Baer Brakes 4262256MG is an SS4 rear brake kit for Ford 8.8 inch C-clip rear ends, built with a 2.5 inch axle standoff and a 4×4.25 bolt pattern. It places a 4-piston S4 caliper in Monster Green on a 12.0 inch, one-piece slotted, drilled, zinc-plated rotor.
Baer’s backing plate doubles as the caliper mount and houses a modern one-piece park brake shoe assembly. Stainless braided hoses come with the kit. The pad type is DR1 or HB100, with an FMSI number of DR1-C, and the seals are T compliant dust and weather seals. The 12 inch SS4 fits most 16 inch or larger wheels.
Key features
- S4 four-piston caliper manufactured in Phoenix, Az
- Forged or billet aluminum body, CNC machined in the US
- Powder coated finish in Monster Green
- Hard anodized aluminum pistons with stainless steel abutments
- Dual seals rated for dust, weather and pressure
- One-piece slotted, drilled, zinc-plate rotor
On the trail
Rear disc brakes on a solid-axle truck see more heat and water than many street setups, especially on long descents or after creek crossings. A one-piece slotted rotor sheds water and gas more readily than a smooth disc, but the pads still need to be bedded in after a pad change so the friction surface transfers evenly.
Park brake function on a rear disc setup depends on the shoe adjustment and the cable path. Shoes that drag or cables that bind can overheat the rotor, so check the adjustment after the first few trail runs and whenever the vehicle sits for long periods.
- Re-check caliper bolts after the first few trail runs
- Keep brake fluid fresh, since heat cycling degrades it
- Replace pads when the wear indicator or friction material gets thin

Vehicle fitment
This kit is not tied to listed vehicles. Its fitment points are a Ford 8.8 inch axle flange, C-clip rear axle design, 2.5 inch axle standoff and 4×4.25 bolt pattern. Template S113E lets you check the rotor and caliper position against your axle and wheel before you commit.
Wheel clearance depends on the wheel style, and Baer does not guarantee fit with every wheel. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The one-piece park brake shoe assembly sits in the backing plate, and park brake cables are not part of the kit, so plan for cables separately. Use the NAS stainless hardware that comes pre-assembled on the rotor. Because this is a braking component, test the pedal and park brake carefully before any road use.
What’s included
The kit contains the S4 four-piston rear calipers in Monster Green, one-piece slotted, drilled and zinc-plated rotors with pre-assembled NAS stainless hardware, the Baer backing plate with one-piece park brake shoe assembly, and stainless braided hoses.
