Overview
The Baer Brakes 54155-020 is a front Claw performance brake rotor for the 2007–2009 Ford Edge and 2007–2009 Lincoln MKX, both listed with front-wheel drive only. It is a direct replacement for the factory front disc, built with a cross-drilled and slotted friction surface that lets gas and dust escape from between the pad and rotor during braking.
The drilled and slotted face supports a more consistent pedal feel and reduced brake fade during repeated stops. The rotor is one-piece full-cast iron, vented, with a directional friction surface and a zinc-plated finish that shows through open-center wheels. Front-drive Edge and MKX owners looking for a performance front rotor can match the part by number, 54155-020.
Key features
- Cross-drilled and slotted friction surface that carries gas and dust away from the pad face
- Enhanced vane structure built from premium materials for cooling and durability
- Premium, mill balanced direct replacement rotor
- Chamfered cross-drilled holes intended to minimize stress cracking
- Zinc-plated finish for a bright look behind open-center wheels
- Directional friction surface on a vented, one-piece full-cast rotor
Front-drive brake service
Front brakes do most of the work on a front-wheel drive crossover, so rotor condition shows up quickly in pedal feel. Heavy use of the front pads can leave a lip at the outer edge of the rotor, which makes new pads chatter if not removed before fitting. A rotor with a directional friction surface should be checked for correct orientation each time a wheel comes off.
Brake fluid and caliper slide pins are often replaced alongside rotors and pads on these vehicles. Fresh fluid helps keep pedal feel steady during repeated stops, and clean slide pins let the pads release evenly. Check the wheel hub and bearing for play while the rotor is off, since runout caused by a worn hub reads as a pulsing pedal.
- Replace pads when the friction material is near its wear indicator
- Bed in new pads on a clear road before aggressive use
- Torque lug nuts in a star pattern after fitting

Vehicle fitment
Covers the 2007–2009 Ford Edge (front, front-wheel drive) and the 2007–2009 Lincoln MKX (front, front-wheel drive). Drive type matters as much as year and model.
All-wheel-drive Edge and MKX models are not covered by this part, and other model years are outside the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
These are direct replacements, so the factory front rotor comes off and the cross-drilled, slotted rotor goes on in its place. The friction surface is directional, so check the rotor’s orientation before it goes on the hub. Bed in new pads as the pad maker directs before relying on hard stops.
What’s included
The package holds two direct replacement rotors.
Not included: the ABS tone ring, which is not part of this kit.
