Overview
The Baer Brakes 54152-020 is a set of rear Claw performance brake rotors for the 2007-2017 Ford Expedition and 2007-2017 Lincoln Navigator. These are direct replacement rotors, meant to take the place of the factory rear rotors on those vehicles. Each rotor uses a slotted and cross-drilled friction surface, a layout Baer says lets gases and dust escape from between the pad and rotor during braking.
The drilled and slotted face is designed to support a more consistent pedal feel and reduced brake fade. The rotors are zinc-plated, which gives a brilliant look in open center wheels where the rotor face shows. Owners who want a rear brake upgrade on these two SUVs should confirm the part number and fitment before choosing a rotor.
Key features
- Slotted and cross-drilled friction surface that vents gases and dust from between the pad and rotor
- Enhanced vane structure, which Baer says improves cooling and durability
- Premium, mill-balanced direct replacement rotor
- Chamfered cross-drilled holes, intended to reduce stress cracking
- Zinc-plated finish for open center wheels
- One-piece full cast vented construction in cast iron
Rear brake service tips
Rear rotors work with the pads and calipers to slow the vehicle, and on a heavy SUV like the Expedition or Navigator they absorb a lot of heat during repeated stops. Worn rotors often show up as pulsation in the pedal, a grinding noise, or a lip forming at the outer edge of the friction surface. Checking rotor thickness against the minimum stamped on the casting or in a service manual helps decide whether the old parts can stay in service.
Rear rotors are usually installed with new pads, and bedding in the new pads and rotors after installation helps the friction surfaces transfer an even layer of material. Caliper slide pins, boots and hardware should be inspected at the same time, and the hub mounting surface should be cleaned of rust so the rotor sits flat. Vehicles that tow or see steep grades put more load on rear brakes, so inspecting them more often is a sensible habit.
- Measure rotor thickness before installation
- Replace pads together with the rotors
- Clean the hub mounting surface before fitting
- Inspect caliper slide pins and boots

Vehicle fitment
The manufacturer fitment list covers the 2007-2017 Ford Expedition (rear) and the 2007-2017 Lincoln Navigator (rear). Both entries are for rear position only.
Generations outside 2007-2017 and front-axle applications are not covered by this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The ABS tone ring is not included, so the tone ring already on the vehicle needs to be reused. Because these are rear brake components, a qualified technician should inspect the rear brakes after the rotors are installed.
What’s included
A pair of direct replacement rear rotors, sold as a set.
Not included: ABS tone ring.
