Overview
The Baer Brakes 4262654HO is a rear SS4 brake system in Hugger Orange for rear ends with a Ford 8 Inch/9 Inch small bearing housing, combining a 12-inch rotor with a four-piston S4 caliper. It is built for a 5×5.00 inch bolt circle with five lugs, so it targets five-lug rear ends with that flange.
The S4 caliper is a four-piston fixed design with hard anodized aluminum pistons, and the backing plate that holds it also carries a one-piece park brake shoe assembly. The 12-inch rotor is sized for wheels 16 inch or larger, and the kit uses the DR1 or HB100 pad types with FMSI DR1-C.
Key features

- Powder coated caliper finish in Hugger Orange
- Vented one-piece 12-inch rotor, slotted, drilled and zinc plated
- Backing plate with a built-in park brake shoe assembly
- Braided brake hoses, DOT approved, included
- Manufactured in Phoenix, AZ from CNC-machined forged or billet aluminum
Before you buy
Rear disc conversions on a small bearing axle depend on matching the flange, bolt circle and wheel clearance before anything else. Check the axle and wheel details first, then confirm the template fit, since a rotor that clears the hub can still crowd the inside of a spoke wheel.
The park brake shoes sit inside the backing plate, so parking performance depends on the shoes, adjuster and cables working together. Replace worn pads and inspect the rotor surface when the kit is installed, and expect to bleed the hydraulic system after any caliper or hose work. Braided lines are a sensible match for a new caliper because they hold up well to heat and flex.
- Measure the wheel bolt pattern against the 5×5.00 inch listing before mounting
- Check the inside clearance of the wheel with the caliper in place
- Inspect the parking brake cables for fraying or sticking
- Keep fluid levels topped up during the first bleed

Installation notes
Because the park brake shoes sit inside the backing plate, the parking brake hardware arrives with the rear kit. Test the fit with template S113E against your wheel first, since the 12-inch rotor is sized for wheels 16 inch and larger. Have a qualified technician bleed and test the brakes before the truck is driven on public roads.
