Overview
The Baer Brakes 4262189CY is a Pro Plus rear disc brake kit for Ford 9 inch early big bearing rear ends, built around a 6-piston 6P caliper finished in Comp Yellow and a 14 inch two-piece rotor. It is sold as a complete kit on a 5×5.00 bolt pattern with 5 lug nuts.
Baer’s backing plate serves as the caliper mount and also houses a one-piece park brake shoe assembly, so the kit covers the park brake as well as service braking. Staggered pistons aim to minimize uneven pad wear, and dual seals guard against dust, weather and pressure. Vehicle fitment is covered in the section below.
Key features
- Six-piston 6P fixed caliper with stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 14.0 inch vented two-piece rotor with billet aluminum hat
- Slotted, drilled and zinc plated rotor surface
- CNC machined from US-sourced forged or billet aluminum with a powder coated finish, made in Phoenix, Az
- Steel braided brake hoses, DOT approved
Care and inspection
A rear disc conversion changes how the axle handles braking, so the rotor, caliper and backing plate work as one system. Because the park brake shoe assembly sits on the same backing plate, the parking function depends on the whole assembly being installed square and seated correctly. Check that the caliper bracket is tight and that the rotor spins without drag before the first drive.
Pads wear at different rates depending on driving. Inspect pad thickness and rotor surface at regular intervals, especially after towing or heavy trail use. Signs of a worn rotor include pulsing in the pedal, scoring deeper than a light surface pattern, and a lip forming at the outer edge. Rotors and pads are often replaced together to keep braking even.
- Torque hardware to specification after the first few drives
- Inspect hoses for chafing against the axle and suspension
- Keep park brake cables adjusted to the shoe assembly
- Bed in new pads gradually before hard stops

Vehicle fitment
It is built for Ford 9 inch early big bearing rear axle housing ends with a 5×5.00 bolt pattern, so the axle flange and wheel requirements are the key checks. Wheel fit varies by style, so compare template Q082P against your wheel before ordering.
Installation notes
The 14.0 inch rotors come pre-assembled with NAS high grade stainless hardware. Measure wheel clearance against template Q082P before mounting, because the rotor needs wheels of 18.0 inch minimum diameter. Brake work should be done by someone experienced with rear disc conversions.
What’s included
The kit includes the 6P caliper system on the Baer backing plate, the 14.0 inch vented two-piece rotor pre-assembled with stainless hardware, a one-piece park brake shoe assembly, and stainless braided hoses with hardware.
Not included: Park brake cables.
