Overview
The Baer Brakes Extreme Plus rear brake system, part number 4262691CY, is a complete rear disc brake kit in Comp Yellow for 6-lug Ford trucks. It combines a 1-piece Monoblock, 6-piston 6S caliper with a 15.0 inch two-piece slotted, drilled and zinc-plated rotor. Fitment covers the 2009–2011 Ford F-150.
The kit is also associated with 2010–2011 Ford Raptor applications and with both 2WD and 4WD drivetrains. It is sold with rotors, calipers, brackets and hardware and is built around the D1247 pad type and the N125U template.
Key features
- 1-piece Monoblock, 6-piston 6S caliper with powder coated finish, made in Phoenix, Arizona
- Caliper body CNC machined from U.S.-sourced 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual dust, weather and pressure seals
- 2-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- Backing plate houses a 1-piece park brake shoe assembly
Rear upgrade considerations
Swapping rear rotors and calipers changes how braking force reaches the axle, so the front brakes, master cylinder and fluid condition all matter when the job is done. Multi-piston calipers and larger rotors can alter pedal feel and bias, which is why many owners have the full hydraulic system checked during installation. A careful bedding routine helps the new friction surfaces settle in evenly.
Heavier trucks often carry larger loads and tires, which speeds up pad and rotor wear on the rear axle. Check pad thickness, rotor surface and caliper slide movement at regular intervals, and replace worn hardware before it causes noise or uneven contact.
- Inspect caliper slide pins for free movement
- Bed in new pads gently before heavy towing
- Re-torque lug nuts after the first few drives

Vehicle fitment
This kit covers the 2009–2011 Ford F-150. Ford Raptor applications are associated with it as well, and it is made for 2WD and 4WD drivetrains. Years outside 2009–2011 and other F-150 generations fall outside the covered range.
Model years outside 2009–2011 and other Ford F-150 generations are not on this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The 15.0 inch rotor suits most wheels 19 inch or larger, so check wheel clearance around the caliper. Compare the N125U template with your wheel before mounting, since wheel styles vary. Brake work should be handled by a qualified technician.
What’s included
The kit includes the 15.0 inch rotors pre-assembled with stainless hardware, the 6S calipers, the park brake shoe assembly in the backing plate, and the brackets and hardware.
Not included: Park brake cables and brake hoses, which are re-used from the original vehicle.
