Overview
The Baer Brakes 4262690CY is an SS4 Plus 11-inch rear disc brake kit in Comp Yellow for rear ends with Ford 8 Inch/9 Inch Small Bearing housing ends. It pairs a four-piston S4 caliper with an 11-inch two-piece slotted, drilled and zinc-plated rotor, and it fits the 5×4.50 and 5×4.75 inch bolt pattern.
The kit suits wheels 15 inches and larger. The rotors arrive pre-assembled with NAS high grade stainless hardware, and the mounting brackets, stainless braided hoses and hardware are all included. Wheel styles differ widely, so Baer does not guarantee fit to every wheel and recommends checking clearance with its S125A template.

Before you buy
Rear disc conversions change how the whole axle carries braking load, so it helps to look past the caliper and rotor before choosing a kit. A larger rotor and multi-piston caliper generally produce more clamping force at the wheel, but the pads, lines and pedal feel should be matched so braking stays predictable. Drum setups often served as a parking brake, and this kit does not include park brake components, so plan a separate parking solution if you rely on the rear for that job.
Wheel clearance is the other common issue. Offset, backspacing and the position of the caliper behind the spokes all decide whether a wheel clears the caliper and rotor. Test-fit with a sample wheel before the axle goes back under the vehicle, and keep oil and grease off the friction faces during assembly, since contamination reduces stopping performance.
- Identify the axle flange and housing end style before ordering
- Plan for a separate parking brake solution if needed
- Re-check lug and bracket fasteners after the first few drives

Vehicle fitment
The kit is made for the Ford 8 Inch/9 Inch Small Bearing rear axle flange. Confirm that your rear end uses that housing end style before ordering.
This kit is for small bearing housing ends and does not cover big bearing housing ends. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check clearance with Baer’s S125A template before mounting, since Baer cannot guarantee fit to every wheel style. The rotors arrive pre-assembled, and the brackets and braided hoses are supplied with the kit. Brake work should be performed by a qualified installer.
