Overview
The Baer Brakes 4262205MG is an Extreme Plus rear brake kit for Ford 9 Inch early big bearing axle flanges, with a 5 lug, 5×5.00 inch bolt pattern. Sold as a kit, it pairs a 1-piece Monoblock 6-piston, 6S caliper with a 14 inch, 2-piece slotted, drilled and zinc-plated rotor.
The Extreme Plus is a performance rear brake upgrade. The 14 inch rotor fits most 18 inch or larger wheels, and the kit uses the D1247 pad type. Stainless braided hoses, pre-assembled rotors and a backing plate carrying a 1-piece park brake shoe assembly are included. Axle flange and wheel clearance are the main points to confirm before ordering.
Key features
- 1-piece Monoblock, 6-piston, 6S caliper manufactured in Phoenix, AZ
- CNC machined caliper body from U.S.-sourced 2618 aluminum forging with powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled, zinc-plated rotor with billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- Backing plate serves as the caliper mount and houses a 1-piece park brake shoe assembly
Choosing the right setup
A larger rear rotor and multi-piston caliper change the load on the axle bearings, hub and brake lines compared with a stock setup, so the rest of the rear end should be inspected when the kit goes in. Check the wheel bearings, axle seals and brake lines for condition, since a fresh brake package on a worn hub often shows problems sooner than expected.
Parking brake performance depends on the shoe assembly in the backing plate and the cables that operate it. Cables and adjustment are often replaced together with a rear brake upgrade, so set aside time to adjust the park brake after the first few stops and recheck it after the initial break-in period.
- Inspect wheel bearings and axle seals when the rear is opened up
- Replace worn brake lines before fitting new hoses
- Adjust the park brake after the first few stops

Vehicle fitment
The kit is built around the Ford 9 Inch early big bearing axle flange and is used on a rear axle, not tied to a specific year, make, model or trim.
Confirm your axle flange, bolt pattern and wheel template before ordering. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Baer cannot guarantee fit of this brake system into every wheel style. Use template N085P to compare rotor and caliper clearance against the wheel you plan to run before mounting. Have the rear brake assembly installed by a technician familiar with hydraulic brakes and park brake adjustment.
