Overview
Fire Red is the finish on this Baer Brakes SS4 Plus rear kit, part 4262260FR, which pairs a 4-piston S4 caliper with a 13 inch, 2-piece slotted, drilled, zinc-plated rotor. It is built for the Ford 9 Inch Early Big Bearing axle flange and a 5×4.50/5×4.75 bolt pattern.
Baer’s backing plate serves as the caliper mount and also carries a one-piece park brake shoe assembly, keeping the parking brake in the same housing. The DR1-C pad type is specified, and the caliper body is powder coated in Fire Red.

Before you install
Before the kit goes on, confirm what the box contains and what it does not. The park brake shoe assembly is part of the backing plate, but park brake cables are not included, so the existing cables will be reused. Inspect them for fraying, stiffness and corrosion, since a worn cable can stop the parking brake from holding even when the shoes are new.
Rear brake work also involves the axle, the bearing and the brake line. Hoses should be routed so they do not rub against the suspension or the axle tube, and the system should be bled after any hose or caliper work. A test drive in a safe area lets you check pedal feel and parking brake hold before using the vehicle on the trail or the road.
- Inspect and reuse or replace existing park brake cables
- Route braided hoses clear of suspension and axle parts
- Bleed the system to remove air after hose or caliper work
- Test parking brake hold in a safe area before regular use

Vehicle fitment
Compare the Ford 9 Inch Early Big Bearing axle flange and 5×4.50/5×4.75 bolt pattern with your rear axle and wheels. Verify your vehicle’s year, model and trim against the axle before ordering.
Wheel styles vary, so use the S135H template to check the wheel before mounting.
Installation notes
Rotors come pre-assembled with NAS high grade stainless hardware, and the caliper mounts to the backing plate, which also houses the park brake shoe. Stainless braided hoses are part of the package. Work on rear brakes calls for a technician familiar with disc brake service.
