Overview
The Baer Brakes 4262258CY is a complete SS4 Plus rear disc brake kit for Ford 8.8 inch C-Clip rear ends with a 2.5 inch axle standoff. It pairs a 4-piston S4 caliper finished in Comp Yellow with a 13 inch two-piece slotted, drilled, zinc-plated rotor and is built for 5 lug wheels on a 5×4.50 bolt pattern.
Baer uses its backing plate as the caliper mount and as the housing for a modern one-piece park brake shoe assembly, so the parking brake is part of the rear setup rather than an add-on. The kit suits owners who want a matched, purpose-built rear brake package with stainless hardware and braided lines, sold as one complete kit.
Key features
- Four-piston S4 caliper, manufactured in Phoenix, Arizona, from CNC-machined forged or billet aluminum sourced in the US
- Powder coated caliper finish in Comp Yellow
- Hard anodized aluminum pistons with stainless steel abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- DOT approved steel braided brake hoses included with the kit
Before you buy
A rear disc conversion changes more than the brakes at the wheel. The backing plate, caliper mount and parking brake shoe all have to line up with the axle housing, so measure the axle flange and standoff before committing to a kit. Wheel offset and backspacing matter too, because a rotor and caliper that look correct on a bench can still rub the inner barrel of a wheel once mounted.
Pad compound and rotor choice affect how the system feels on pavement and on the trail. Mud and water load pads and rotors differently than dry roads do, so this setup suits drivers who expect repeated heat cycles and wet conditions. Plan on a bed-in procedure after installation and keep the rotor surface free of grease before the first stop.
- Axle flange type and standoff
- Wheel diameter and inner clearance
- Parking brake cable routing
- Brake fluid compatibility with existing lines
- Installer experience with rear disc conversions

Vehicle fitment
The kit is not matched to a specific year, make, model or trim. It is built for a Ford 8.8 inch flange on a C-Clip rear end with a 2.5 inch axle standoff, and it calls for a wheel with a minimum diameter of 17.0 inch. Verify fit against your vehicle’s year, model and trim before you order.
Confirm your vehicle’s year, model and trim before ordering. Axles that are not Ford 8.8 inch C-Clip units with a 2.5 inch standoff are not covered by this kit.
Installation notes
Rotors arrive pre-assembled and the stainless braided hoses and hardware are included, so the hydraulic side is supplied with the kit. The park brake shoe sits inside the backing plate, but park brake cables are not included, so confirm your existing cables suit this setup. Lay the S135H template against the wheel before mounting, since Baer cannot guarantee fit across all wheel styles. Brake work is safety-critical, so have a qualified technician install and test the system.
