Overview
The Baer Brakes Extreme front brake system 4261397CY is a Comp Yellow kit for the 2010–2026 Ford F-150, covering 2WD and 4WD trucks and Raptor models. Baer’s 1-piece Monoblock six-piston 6S caliper clamps a 15-inch vented rotor with slotted, drilled and zinc-plated faces.
Each caliper body is CNC machined from 2618 aluminum forging, produced in Phoenix, Arizona, and finished with powder coat in Comp Yellow. Stainless steel pistons and abutments are used, with staggered pistons that aim for even pad wear and dual seals against dust, weather and pressure. Pads are the D1247 type, and the wheel bolt pattern is 6x135mm.
Key features
- 6S Monoblock caliper, 1-piece, six pistons
- CNC-machined from 2618 aluminum forging
- Staggered pistons to minimize uneven pad wear
- Noise suppression clips and stainless steel abutments
- 1-piece vented rotor, 15.0 inch, slotted and drilled
- Zinc-plated rotor surface with Comp Yellow powder coat on the caliper
Caliper material explained
Caliper bodies are made from cast iron, steel or aluminum, and each has trade-offs in weight, heat handling and cost. Aluminum calipers are lighter than many iron units, which reduces unsprung weight at the hub. Heat management still depends on pads, rotor size and airflow through the wheel.
Monoblock designs use a single piece body, which avoids a split housing that can need more attention over time. Stainless steel pistons resist corrosion in road salt and wet conditions, so regular cleaning of the caliper area helps keep them moving freely.
When comparing options, look at the caliper material alongside the rotor, pad type and wheel clearance rather than in isolation.
- Weigh caliper material against intended use
- Consider heat handling for towing
- Check airflow around the caliper
- Keep pistons clean and free moving

Vehicle fitment
The kit fits the 2010–2026 Ford F-150 for 2WD and 4WD, Raptor models included, on the front axle.
Earlier F-150 years and other Ford trucks are not on this fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Mounting brackets and hardware are included, so no separate brackets are needed for this front system. The kit re-uses the factory OE hoses. Baer advises using template N063U to check wheel fit, because wheel styles and manufacturers differ widely. Make a low-speed brake test in a safe area before normal road use.
What’s included
Included are the 6S Monoblock caliper, the 15-inch 1-piece rotor, and mounting brackets with hardware.
Not included: Wheels are not part of the system. Check the package contents against your installation before starting, and plan pads around the D1247 type.
