Overview
The Baer Brakes Extreme Plus rear disc brake kit in Grabber Blue, part number 4262688GB, fits the 2012–2018 Ford F-150 in 2WD and 4WD. It also fits the Ford Raptor in the same years.
Its core is a 1-piece monoblock 6-piston caliper, designated 6S, clamping a 15 inch 2-piece rotor. The set suits wheels 19 inch and larger and re-uses the factory hoses and park brake hardware.
Key features
- One-piece monoblock housing carrying six pistons
- Staggered piston layout intended to minimize uneven pad wear
- Stainless steel pistons with stainless abutments and noise suppression clips
- Dual dust, weather and pressure seals
- Zinc-plated, slotted and drilled 2-piece rotor with billet aluminum hat
- 2618 aluminum forging, CNC machined from U.S. sourced material
- Grabber Blue caliper color, manufactured in Phoenix, AZ
Rear brake upgrade planning
Upgrading only the rear brakes on a truck shifts some stopping work toward the back axle. A six-piston caliper gives the pads a firm, even squeeze on the rotor, which many drivers notice as steadier braking when the truck is loaded. The larger rotor surface also spreads heat across more area, which helps during repeated stops on grades.
Plan the rest of the brake system around the new rear hardware. Brake fluid absorbs moisture over time, so a fresh fill before the swap keeps the system responding well. Rubber lines that were re-used should be checked for cracks and soft spots, since a line that balloons under pressure can cause a spongy pedal.
Wheel and tire changes affect clearance as well. A taller or wider tire can contact the caliper when the steering turns, so measure the space before committing to a new wheel setup.
- Flush brake fluid before the swap if it is old
- Inspect rubber lines for swelling or cracking
- Check the parking brake adjustment after installation
- Look for uneven pad wear on the rear axle

Vehicle fitment
It fits the 2012–2018 Ford F-150 in 2WD and 4WD, and the Ford Raptor 12-18 is also covered. It is a rear brake upgrade for those trucks.
Installation notes
Compare the rotor and caliper clearance with the intended wheel using the N125U template before mounting. Plan on re-using the truck’s existing park brake and hoses. Stopping performance changes with any brake swap, so pads should be bedded and the hydraulic lines bled afterward.
What’s included
Monoblock 6S calipers, 2-piece rotors with pre-assembled NAS high grade stainless hardware, and all brackets and hardware.
Not included: Factory hoses and the park brake assembly are re-used rather than supplied. Brake pads are D1247 type; check the package contents against your installation before starting.
