Overview
The Baer Brakes 4262186MG is a Pro Plus rear disc brake kit for Ford 9 inch early big bearing axle housings with a 5×5.00 wheel bolt pattern. It pairs a 6-piston, 6P fixed caliper with a 13 inch two-piece rotor in Monster Green.
Baer designed this kit for owners who want a bigger rear brake package on a 9 inch axle. The backing plate doubles as the caliper mount and holds a modern one-piece park brake shoe assembly. Rotors come pre-assembled with NAS high grade stainless hardware, and stainless braided hoses are included with the kit.
Key features
- 6-piston, 6P fixed rear caliper with a Monster Green powder coated finish
- Two-piece slotted, drilled and zinc plated rotor with a billet aluminum hat
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons intended to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- CNC machined components made from US sourced forged or billet aluminum
- Uses the common D0731 FMSI brake pad type
- Dust and weather seals described by Baer as T compliant
Choosing the right setup
A bigger rear brake package changes how the whole rear end behaves, so the setup is best judged as one system. The rotor, caliper and pads work together with the wheel, and brake line routing and park brake hardware need to be sorted out as part of the same job. Keeping the parts matched to the axle and the driving you do avoids surprises once the truck is back on the road.
Monster Green is a finish, not a performance rating, so it should not drive the choice on its own. Compare overall fit, wheel clearance and pad type first. Brake fluid, lines and the master cylinder deserve a check too, since a larger caliper asks more of the hydraulic side.
- Confirm the park brake cable setup before the install starts
- Use fresh brake fluid suited to the system
- Inspect the rear hard lines for kinks and corrosion
- Check wheel bearings and axle seals during teardown
- Torque wheel fasteners to the specification for your vehicle

Vehicle fitment
The kit is built for the Ford 9 inch early big bearing axle flange. Use template Q082H to check wheel clearance against the 17.0 inch minimum wheel diameter.
Before ordering, make sure the vehicle year, model and trim suit the axle requirements. Axle housing and flange compatibility should be verified, since the axle flange name alone does not confirm a vehicle match.
Installation notes
The park brake shoe assembly is built into the backing plate, so the rear brake hardware is installed as one unit. Check wheel clearance with the Q082H template before mounting the rotor, since the minimum wheel diameter is 17.0 inch and Baer cannot guarantee fit with every wheel style.
What’s included
Pre-assembled rotors with NAS high grade stainless hardware, a backing plate with one-piece park brake shoe assembly, a 6P caliper, and stainless braided hoses with hardware.
Not included: Park brake cables.
