Overview
The Baer Brakes SS4 Plus 11.0 inch rear brake kit in Grabber Blue, part 4262690GB, is built for Ford 8 inch and 9 inch rear axles with small bearing housing ends. Its four-piston S4 caliper uses fixed mounting and clamps an 11.0 inch vented, two-piece rotor.
The kit is made for five-lug wheels on a 5×4.50/5×4.75 bolt pattern and a minimum wheel diameter of 15.0 inch. Grabber Blue is the caliper finish. Confirm fit for your vehicle’s year, model and trim before ordering.
Key features
- S4 caliper with four pistons and a two-piece body, powder coated
- Hard anodized aluminum pistons sitting on stainless steel abutments
- Noise suppression clips included in the caliper hardware
- Dual-seal design with a dust and weather seal plus a pressure seal
- Two-piece rotor, slotted and drilled with zinc plating, on a billet aluminum hat
- Stainless hardware pre-assembled on the rotors, with steel braided hoses
Axle housing and bolt pattern
Ford 8 inch and 9 inch rear axles have been built with several bearing and flange arrangements over the years, so the housing style is the first thing to confirm. Five-lug wheels on a 5×4.50/5×4.75 pattern also need to match the hub, and a mismatch will prevent the rotor from seating correctly. Measure your axle ends before ordering rather than relying on memory.
A four-piston caliper with a two-piece rotor depends on clean mounting faces, so wipe the hub and rotor hat before assembly and check that the rotor sits flat against the flange. Recheck the bolt torque after the first few drives, since new mating surfaces settle slightly.
- Clean the hub face and bolt holes before assembly
- Check wheel clearance around the caliper
- Have a qualified technician handle the brake lines

Vehicle fitment
Start with the axle housing: Ford 8 inch and 9 inch rear axles with small bearing housing ends. That identifies the axle housing type, and the five-lug bolt pattern is the second check.
Match your rear axle housing and five-lug bolt pattern before ordering. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Brackets and braided hoses come in the set, so the hose run needs no separate purchase. Use the S125A template to check wheel clearance; the kit suits wheels of 15 inch or larger.
What’s included
Rotors pre-assembled with stainless hardware, four-piston S4 calipers in Grabber Blue, mounting brackets, stainless braided hoses and hardware.
Not included: The park brake, which the specifications mark as not included.
