Overview
The Baer Brakes Pro Plus 14.0 inch rear brake system, part number 4262151MG, is a complete rear disc kit for Ford 9 inch rear ends with early big bearing housing ends. Its 6P six-piston fixed calipers are finished in Monster Green and clamp two-piece slotted, drilled, zinc-plated rotors.
Baer’s backing plate acts as the caliper mount and also houses a one-piece park brake shoe. The package uses D0731 pads and stainless steel pistons, and its dust and weather seals are DOT-compliant. The wheel bolt pattern is 5×4.50/5×4.75 with 5 lug nuts.
Key features
- Six-piston 6P caliper with staggered pistons to limit uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals keep out dust, weather and pressure
- Vented two-piece rotor, slotted and drilled with a zinc-plated surface, on a billet aluminum hat
- Powder-coated finish with calipers CNC machined from US-sourced forged or billet aluminum
- Stainless braided hoses rated DOT approved
- Assembled in Phoenix, AZ
Before you buy
Calipers, rotors and backing plates are sold as matched sets because the rotor hat, caliper bracket and axle flange must line up exactly. Before ordering, look at the axle bearing style and flange shape, then measure the space between the rotor and the inside of the wheel so the rotor and caliper have room to sit.
Stainless braided hoses flex less than rubber lines and hold their feel longer, but they still need periodic inspection for chafing, weeping fittings and worn crimps. A good habit is to bleed the system after any hose or caliper work and to check pad thickness on the same schedule as the rotors.
- Match the axle bearing style to the kit
- Measure wheel clearance before mounting
- Inspect braided hoses for chafing and leaks

Vehicle fitment
It is built for the Ford 9 inch rear axle with early big bearing housing ends, so the axle flange has to match. Check your axle flange against this kit before purchase.
Not for the late big bearing housing ends. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotors come pre-assembled with NAS stainless hardware, and stainless braided hoses are included. Baer advises checking wheel clearance with template Q082P, since it cannot guarantee fit with every wheel style. Park brake cables are not included, so they need to be sourced separately.
What’s included
Kit with 6P calipers, two-piece rotors with NAS hardware, backing plate with one-piece park brake shoe, stainless braided hoses and mounting hardware.
Not included: Park brake cables.
