Overview
The Baer Brakes 4262653CY is a rear SS4 Plus brake system kit for Ford 8 inch and 9 inch small bearing housing ends. It pairs a four-piston S4 caliper in Comp Yellow with a 13 inch two-piece slotted, drilled, zinc-plated rotor and uses the popular DR1-C pad type.
Rotors come pre-assembled with NAS high grade stainless hardware. The backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly. Stainless braided hoses and hardware are included. The 13 inch SS4 Plus fits most 17 inch or larger wheels, but fit with every wheel style cannot be guaranteed, so compare template S135H with your chosen wheel before mounting.
Key features
- Four-piston S4 caliper with hard anodized aluminum pistons and stainless steel abutments
- Dual dust, weather and pressure seals
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat
- One-piece park brake shoe assembly built into the backing plate
- Powder coated finish, CNC machined from US sourced forged or billet aluminum
- Noise suppression clips included with the caliper hardware
- Stainless braided hoses rated DOT approved
Before you install
A rear disc brake upgrade changes how the axle handles stopping force, so the setup should be matched to the vehicle’s weight, tire size and typical use. On the trail, a larger rotor and four-piston caliper help hold steady braking when the vehicle is loaded or driven down grades, while on pavement the same parts reduce the load each pad carries during repeated stops.
Park brake function deserves attention before the kit goes on. When the shoe assembly is built into the backing plate, the cables and lever arrangement need to match that layout. Old cables that are stiff, frayed or rusted should be replaced rather than reused alongside new hardware.
- Check hub and bearing condition before mounting
- Replace any brake lines removed during the swap
- Bleed the system after every hose change

Vehicle fitment
It is built for Ford 8 inch and 9 inch small bearing axle housing ends, a rear axle type rather than a specific model year. Fit depends on the axle flange and the 5×5.00 inch bolt pattern, so check both against template S135H.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The park brake shoe assembly is part of the one-piece backing plate. Park brake cables are not included, so plan for a separate cable setup. The rotors arrive pre-assembled, so finish the template check before mounting the rotors to the hub.
What’s included
The kit includes the S4 calipers on a backing plate with a one-piece park brake shoe assembly, two-piece rotors pre-assembled with NAS stainless hardware, and stainless braided hoses with hardware. Park brake cables are not included.
