Overview
The Baer Brakes 54111-020 is a set of rear Claw performance rotors for the 2004-2011 Ford F-150, covering Lariat, STX, XL, XLT and Harley-Davidson Edition trucks with 6-lug hubs in 2WD and 4WD configurations. Each rotor is one-piece, full cast iron and vented, and it is built as a direct replacement for the factory rear discs.
The rotor uses a slotted and cross-drilled friction surface. The slots and holes route gases and dust out from between the pad and rotor during braking, which supports a more consistent pedal feel and reduced brake fade. Enhanced vane structure improves cooling, the drilled holes are chamfered to limit stress cracking, and each rotor is mill balanced. The zinc-plated finish gives a bright appearance behind open center wheels.
Key features
- Slotted and cross-drilled face that vents gases and dust from between pad and rotor
- Enhanced vane structure and premium materials for cooling and durability
- Premium, mill balanced, direct replacement design
- Chamfered cross drilled holes to reduce stress cracking
- Zinc-plated finish for open center wheel applications
- Directional brake surface
Choosing and inspecting rear rotors
Rear rotors carry less braking load than the fronts on most trucks, but they still need to run true and flat against the pads to deliver steady stops. A rotor that has warped, worn unevenly or built up a rust ridge at the outer edge can cause pulsing through the pedal and a pull under braking. Replacing the rotors as a pair keeps both sides wearing at the same rate and avoids a mismatch that can affect straight-line stops.
Slotted and cross-drilled rotors move gas and debris away from the pad face, but the surface still wears over time. Inspect the friction surface for deep scoring, hot spots or cracks around the drilled holes at each pad change. Measure thickness against the discard limit before reinstalling, and keep the hub face clean so the rotor seats without runout.
- Replace pads at the same time as the rotors when possible
- Check the hub and wheel bearing for play before fitting
- Wash off brake dust and grit when the truck is serviced

Vehicle fitment
The manufacturer fitment list for this part names the 2004-2011 Ford F-150 with Harley-Davidson Edition, Lariat, STX, XL and XLT trim names, for rear 6-lug applications in 2WD and 4WD.
Installation notes
Before fitting, confirm your truck has rear disc brakes with 6-lug hubs, then clean the hub surface and remove any rust scale so the rotor sits flat. Check the rotor’s directional marking so the brake surface is oriented as intended. Lift and support the truck on stands, not a jack.
What’s included
A pair of rear one-piece rotors, sold as a set.
Not included: brake pads and hardware.
