Overview
The Baer Brakes Extreme Brake System 4261397FR is a Fire Red front disc brake system for the 2010–2026 Ford F-150, including Raptor and both 2WD and 4WD models. Its six-piston caliper is a 1-piece Monoblock design, designated 6S, mounted to a 15-inch rotor.
Each caliper is CNC machined from 2618 aluminum forging in Phoenix, Arizona, then powder coated. Stainless steel pistons and abutments sit alongside staggered pistons that help minimize uneven pad wear, and dual seals resist dust, weather and pressure. The system uses the D1247 pad type with a 6x135mm, six-lug wheel pattern.
Key features
- 1-piece Monoblock caliper with six pistons, 6S designation
- Stainless steel pistons, abutments and noise suppression clips
- Staggered piston layout to reduce uneven pad wear
- Dust, weather and pressure dual seals
- 1-piece vented rotor, 15.0 inch, slotted, drilled and zinc plated
- Powder coated Fire Red caliper finish
Things to check
Before the truck leaves the driveway, check that the brake hoses are in good condition, since the factory hoses stay in use. Look for cracking, bulging or seepage at the fittings. Hoses that have aged or been damaged are better replaced during the brake job than after a road issue.
Brake pedal feel changes when calipers and rotors are swapped, so the first stops should be made slowly and in a safe area. A firm, steady pedal is the goal, and a sinking pedal or pulling to one side means the system needs inspection.
After the first few runs, recheck the lug nut torque, since new brake parts and wheel seating can settle.
- Inspect hoses for cracks and seepage
- Confirm pedal feel before normal driving
- Recheck lug nut torque after early use
- Look for pulling under braking

Vehicle fitment
The fitment covers the 2010–2026 Ford F-150 in 2WD and 4WD form, Raptor included, for the front axle. Baer’s application note reads Ford F150 10-26.
Earlier F-150 model years and other Ford models are not covered by this fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The mounting brackets and hardware are included, and the existing OE hoses are re-used, so no new hose run comes with the kit. Fit cannot be guaranteed for every wheel style, so use template N063U to compare clearance with the wheel you plan to run. Check the pedal and look for leaks in a safe place before driving on public roads.
What’s included
The kit includes the 6S caliper, the 1-piece 15-inch rotor, and the mounting brackets and hardware.
Not included: Wheels are not part of the kit. Check the package contents against your installation before starting, since the system is built for the D1247 pad type.
