Overview
The Baer Brakes Pro Plus 14.0 inch rear brake system, part number 4262151FR, is a rear disc brake set for Ford 9 inch rear ends with early big bearing housing ends. It uses 6P six-piston fixed calipers in Fire Red together with two-piece slotted, drilled, zinc-plated rotors.
A backing plate serves as both the caliper mount and the housing for the one-piece park brake shoe. The calipers use stainless pistons and dual seals, and the pads are the D0731 type. The bolt pattern is 5×4.50/5×4.75 with 5 lug.
Key features
- Six-piston caliper design with staggered pistons that aim for even pad wear
- Stainless pistons, stainless abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Vented two-piece rotor with slotted, drilled, zinc-plated surface and a billet aluminum hat
- Powder-coated finish; calipers CNC machined from forged or billet aluminum sourced in the US
- Stainless braided hoses approved to DOT standards
- Phoenix, AZ manufacturing
Choosing the right setup
Rear disc conversions change how the parking brake and hydraulic system work together, so the setup should be planned before the rotors go on. The park brake shoe in the backing plate needs cables and a lever that match the vehicle, and the brake lines should be routed clear of the axle, suspension links and driveline. Bleed the system fully after any line work so the pedal feels firm before the vehicle leaves the driveway.
Pads and rotors wear together, and a larger rotor gives the pads more contact area, which can help under repeated braking on long grades. Check the rotor surface for heat cracks or deep grooves at each service, and replace pads before the backing plate contacts the rotor. Clean the caliper slides and dust seals periodically, and keep brake fluid fresh on the vehicle’s normal service interval.
- Ford 9 inch axles with late big bearing housing ends use a different setup
- Wheel clearance with the chosen wheel style
- Parking brake lever and cable routing

Vehicle fitment
It is built for Ford 9 inch rear ends with early big bearing housing ends. Confirm that your axle flange and bearing style match before ordering.
Late big bearing housing ends are a different configuration. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotors are pre-assembled with NAS hardware and the braided hoses come in the kit. Use template Q082P to test clearance on your chosen wheel, since fit depends on wheel style. Park brake cables must be sourced separately.
What’s included
Fire Red 6P calipers, two-piece rotors, backing plate with park brake shoe, stainless braided hoses and hardware.
Not included: Park brake cables.
