Overview
The Baer Brakes 54091-020 is a set of front Claw performance rotors for the Ford Expedition, Ford F-150 Lightning and Lincoln Navigator 2WD models built from December 1999 into early 2002, with 14 mm studs. Each rotor is one-piece, full cast iron with a cross-drilled and slotted friction surface, a design that helps gas and dust escape from between the pad and rotor during braking.
Baer Brakes presents these rotors as a direct replacement for the factory front discs. The stated goal is a more consistent pedal feel and less brake fade, with a zinc-plated finish that looks bright behind open center wheels. Fitment is limited to the vehicles covered in the Vehicle fitment section below.
Key features
- Slotted and drilled friction surface lets gas and dust escape from between the pad and rotor.
- Enhanced vane structure and premium materials are intended to improve cooling and durability.
- Premium, mill balanced, direct replacement rotor design.
- Chamfered cross-drilled holes are meant to minimize stress cracking.
- Zinc-plated finish for an appearance suited to open center wheels.
- ABS tone ring included.
Choosing a rotor and pad pairing
Rotors and pads wear as a pair, so a new rotor set works best with pads rated for the same duty. Choose a pad compound that suits a cross-drilled, slotted face, and avoid very aggressive pads on a rotor used mainly for street driving. Matching the face to the pad type helps bedding-in stay smooth and keeps noise low.
Trail and tow use put more heat into the braking system, and repeated hard stops can glaze pads or warp a worn rotor. Check the hub, wheel bearings and caliper slide pins during the same job, since a seized caliper will wear a new rotor quickly. Replacing rotors and pads together gives the most even contact across the whole face.
- Inspect caliper slide pins during every rotor change
- Bed in new pads gently after installation

Vehicle fitment
It fits the 2000-2002 Ford Expedition with RWD drive (built 12/99 to 3/18/02), the 1999-2003 Ford F-150 Lightning (built 12/99 to 2003) and the 1999-2002 Lincoln Navigator with RWD drive (built 12/99 to 02/02).
Installation notes
The ABS tone ring is included with each rotor, so no separate ring should be needed. The friction surface is directional, so check rotation direction before fitting. Brake work affects stopping performance, so have a qualified technician install the rotors and test the brakes before driving.
What’s included
The kit includes a pair of direct replacement front rotors.
Not included: brake pads and calipers.
