Overview
The Baer Brakes Extreme Plus rear brake system in Monster Green, part number 4262691MG, is a complete rear disc brake kit for the 09-11 Ford F150 and the 10-11 Ford Raptor. It is designed for 2WD and 4WD trucks that run 6-lug wheels on a 6x135mm bolt pattern.
The centerpiece is a one-piece Monoblock six-piston caliper, the 6S, which clamps a 15-inch two-piece rotor that is slotted, drilled and zinc plated. The backing plate mounts the caliper and houses a one-piece park brake shoe assembly, so parking and service braking share one unit. The caliper is CNC machined from US-sourced 2618 aluminum forging and manufactured in Phoenix, Arizona.
Key features
- Monster Green powder coated one-piece Monoblock caliper with six pistons
- Caliper body CNC machined from US-sourced 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual seals that handle dust, weather and hydraulic pressure
- Two-piece slotted, drilled, zinc-plated rotor on a billet aluminum hat
- Rotors pre-assembled with NAS high grade stainless hardware
Pads and rotor wear
Brake pads are the wear item most owners replace first on a truck with a caliper this size. Pad life depends on towing, grades and how hard the brakes are used, so a visual check at each tire rotation is a sensible habit. Look for uneven wear across the pad face, since staggered pistons are meant to spread load evenly and uneven wear can point to a sticking slide or a seized piston.
The two-piece rotor has a billet hat and a slotted, drilled face, and both can show heat cracks or glazing after heavy use. Check the hat-to-rotor hardware after the first few drives and re-tighten it to the specified value. Keep rotors free of grease, and replace them when they reach the minimum thickness stamped on the rotor.
- Look for uneven pad wear across the face
- Watch for heat cracks along the drilled holes
- Keep grease away from rotor and pad surfaces

Vehicle fitment
The kit is for the 2009–2011 Ford F-150, and it also covers the 10-11 Ford Raptor, in 2WD and 4WD trucks.
Other Ford models, and F-150 years outside the 09-11 range, are not part of these applications. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The kit relies on the truck’s existing park brake cables and hydraulic hoses, so inspect both for wear before the Monster Green calipers go on. 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. Test the park brake and pedal feel before driving, since the parking function is built into the backing plate.
What’s included
The kit includes the 6S Monoblock caliper, the two-piece rotors with billet aluminum hats, the backing plate with its park brake shoe assembly, and the brackets and hardware.
Not included: the truck’s factory park brake cables stay in service, as the kit does not supply new cables.
