Overview
The Baer Brakes SS4 Plus rear brake system in Monster Green, part number 4262260MG, is a complete rear disc brake kit with a 4-piston S4 caliper and a 13 inch, 2-piece slotted, drilled rotor. It fits the Ford 9 Inch Early Big Bearing axle flange and a 5×4.50/5×4.75 wheel bolt pattern.
The backing plate acts as the caliper mount and houses a modern 1-piece park brake shoe assembly, so the parking brake sits inside the same unit as the service brake. The kit uses the DR1-C pad type, and the caliper is finished in Monster Green with a powder coated surface.

Matching the kit to your axle
The axle flange and wheel bolt pattern decide whether the hub will accept this kit, and they should be confirmed before any parts are ordered. Verify the hub face, the lug count and the spacing against the rear end in the vehicle, rather than relying on a general description of the axle family. Because the rotor arrives with pre-assembled hardware, a mismatch is easier to spot before the job starts than after the rotor is mounted.
A two-piece rotor with a billet hat puts the friction surface and the mounting face on separate parts, so the fasteners that hold the hat should be checked after the first few trail runs. Stainless hardware resists corrosion but still needs to be tight. Bed in new pads after installation using gentle stops from moderate speed so the new surfaces seat evenly.
- Verify axle flange and lug pattern before ordering
- Check rotor hat fasteners after initial drives
- Bed in new pads with progressive stops
- Replace park brake cables separately if they show wear

Vehicle fitment
The kit is built for the Ford 9 Inch Early Big Bearing axle flange and the 5×4.50/5×4.75 bolt pattern, so compare those to your axle and wheels. Use the S135H template to check the wheel before mounting. Verify your vehicle’s year, model and trim against this axle first.
Baer cannot guarantee fit into a specific wheel style or manufacturer. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors arrive pre-assembled with stainless hardware, and the park brake shoe assembly is housed in the backing plate. Stainless braided hoses are supplied with the kit. Brake work on a rear axle should be done by someone experienced with disc brake systems.
What’s included
The kit includes the S4 caliper, the 2-piece slotted drilled rotor with billet aluminum hat, the backing plate with park brake shoe assembly, stainless braided hoses and stainless hardware.
