Overview
The Baer Brakes SS4 Plus 4262689GB is a Grabber Blue rear disc brake system for Ford 9 Inch Early Big Bearing rear ends with a 5×4.50/5×4.75 bolt pattern. A four-piston S4 caliper clamps an 11 inch, two-piece, slotted, drilled and zinc-plated rotor, making it a choice for drivers who want a larger rear brake package on this axle.
Rotors are supplied pre-assembled with NAS high grade stainless hardware, along with the mounting brackets, stainless braided hoses and hardware. The kit cannot guarantee fit with every wheel style, so use Template S125A to check the wheel you intend to fit.
Key features
- Two-piece, four-piston S4 caliper manufactured in Phoenix, Az
- CNC machined from U.S.-sourced forged or billet aluminum
- Powder-coated finish in Grabber Blue
- Hard anodized aluminum pistons, stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor on a billet aluminum hat
- Steel braided, DOT approved hoses
Keeping the rear system in service
A rear disc system on a Ford 9 Inch axle is exposed to road spray, gravel and heat cycles, so routine inspection is part of ownership. Check pad thickness, rotor surfaces and caliper slide movement at every service. Sticking slides cause uneven pad wear and can overheat a rotor, so clean and lubricate the slide pins whenever pads are changed, using lubricant rated for brake use.
Two-piece rotors need the hat and friction ring to stay secure, so their fasteners deserve the same attention as the caliper bolts. Inspect the rotor face for cracks or heat marks. The Grabber Blue caliper finish should be cleaned with mild soap and water rather than harsh solvents, which can damage the coating and the seals near it.
- Clean and lubricate caliper slide pins when changing pads
- Check hat fasteners on two-piece rotors
- Wash the caliper with mild soap and water

Vehicle fitment
The kit is made for the Ford 9 Inch Early Big Bearing axle flange and 5×4.50/5×4.75 bolt patterns. Template S125A is the wheel clearance reference.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotors are already assembled, so the work centers on the brackets, braided hoses and rotor mounting. Use Template S125A against the wheel before final assembly. Brake systems are safety-critical, so have a qualified technician install and check the system.
