Overview
The Baer Brakes SS4 brake system, part number 4262261MG, is a rear disc brake kit with a 4-piston S4 caliper and a 12.0 Inch one-piece slotted, drilled and zinc-plated rotor. It comes in Monster Green and is made for Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern.
Baer’s backing plate serves as the caliper mount and also houses the park brake shoe assembly. The rotor fits wheels 16 inches or larger, matching the 16.0 Inch minimum wheel diameter in the specifications. Use the S113E template to check the rotor against the wheel you plan to run.
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 with stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- One-piece slotted, drilled and zinc-plated rotor
Choosing the right setup
A rear disc kit like this one replaces the drum brakes or the earlier disc setup on a live axle, so the choice starts with the housing ends. Match the axle flange and the 5×5.00 bolt pattern to your housing before looking at anything else. The caliper, rotor and backing plate work as a matched system, so changing one dimension usually affects clearance and fit elsewhere.
Wheel clearance deserves close attention. A larger rotor leaves less room inside the wheel, and the 16.0 Inch minimum wheel diameter sets the lower limit for the rotor you can run. Test fit the rotor with the wheel and tire you plan to use, and check that the caliper clears the spokes or wheel face through its full travel. Plan for the rest of the brake hardware to be selected together so the pads, hoses and park brake layout match the kit.
- Confirm the axle flange matches your housing before ordering
- Check wheel clearance around the caliper and rotor
- Plan the park brake cables and routing before assembly
- Inspect the rotor and pads for wear at every service interval

Vehicle fitment
This kit has no vehicle listed. Its fit is defined by the axle: Ford 9 Inch Early Big Bearing rear housing ends with a 5×5.00 bolt pattern and a 16.0 Inch minimum wheel diameter. No year, make or model is given. The Monster Green finish is a caliper color only.
Check the axle flange and bolt pattern against your housing, then compare the S113E template with your wheel. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The backing plate and rotor come with the kit, along with braided hoses. Park brake cables are not part of the package and must be sourced separately. Verify the S113E template against your wheel before mounting, because the 16.0 Inch minimum sets the wheel clearance. Brake components should be installed and bled by someone experienced with disc brake systems.
What’s included
The kit includes the S4 caliper, the one-piece rotor, the backing plate with park brake shoe assembly, braided brake hoses and hardware.
Not included: park brake cables.
