Overview
Baer Brakes offers the Extreme Plus rear brake system in Fire Red under part number 4262691FR. It is a rear disc brake upgrade for the Ford F150 from 09-11 and the Ford Raptor from 10-11, covering 2WD and 4WD trucks on six-lug hubs with a 6x135mm bolt pattern.
The kit centers on a one-piece Monoblock six-piston caliper, the 6S, that grips a 15-inch two-piece slotted, drilled and zinc-plated vented rotor. Stainless steel pistons and noise suppression clips are fitted, and dual seals guard against dust, moisture and pressure. The backing plate mounts the caliper and contains a one-piece park brake shoe assembly. The caliper body is CNC machined from US-sourced 2618 aluminum forging.
Key features
- Six pistons in one body, designated 6S, with a powder coated finish
- Body machined from US-sourced 2618 aluminum forging
- Stainless abutments, pistons and noise suppression clips
- Pistons staggered so the pads wear more evenly
- Dual seals resist dust, weather and pressure
- Slotted, drilled, zinc-plated two-piece rotor on a billet aluminum hat
- Rotor hardware is NAS high grade stainless, pre-assembled at the factory
Choosing wheels and clearance
Wheel fit comes first with a larger two-piece rotor and a multi-piston caliper. The rotor and caliper take up space inside the wheel, so clearance has to be checked against the wheel’s offset and inner barrel depth. A trial fit with the template before mounting the rotor saves time and avoids rubbing that could damage a tire.
Tire size and load rating also matter, since a heavier truck or a taller tire changes how the brakes work over time. Brake upgrades rarely stand alone, so consider inspecting wheel bearings and suspension parts during the same job. Torque the lug nuts in the proper sequence and re-check them after the first few miles of driving.
- Compare wheel offset with the template
- Check the tire load rating for the truck
- Inspect wheel bearings during the same job

Vehicle fitment
This kit fits the 2009–2011 Ford F-150, and its application also covers the Ford Raptor 10-11, in 2WD and 4WD trucks.
Ford models other than the F-150 and Raptor named here, and years outside 09-11 and 10-11, are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Before mounting the Fire Red calipers, examine the truck’s park brake cables and hoses, since the kit is built around them. The 15-inch rotor is made for wheels of 19 inches or larger, and Baer recommends checking the N125U template against the wheel you plan to run. Road test the park brake and pedal feel once the install is finished, before any highway driving.
What’s included
The package contains the 6S Monoblock caliper, slotted and drilled rotors on billet aluminum hats, the backing plate with its one-piece park brake shoe assembly, plus brackets and hardware.
Not included: the truck’s factory park brake cables and hoses are kept in service, because the kit does not supply replacements.
