Overview
The Baer Brakes 54078-020 is a front Claw performance rotor set for 2000–2005 Ford Excursion 4WD trucks and 1999–2004 Ford F-250 and F-350 Super Duty 4WD trucks. Super Duty trucks built from 3/22/99 onward are covered. Each rotor is a one-piece cast iron, vented disc with a slotted and drilled friction face, sold as a set.
These rotors are for the front hubs of large Ford trucks, where a heavier front brake is a common upgrade for towing. The slots and holes help gases and dust leave the pad and rotor interface, which supports a more consistent pedal and reduced fade. The zinc-plated face looks bright behind open-center wheels.
Key features
- Slotted and drilled face clears gases and dust from between pad and rotor.
- Enhanced vane structure using premium materials for cooling and durability.
- Premium, mill balanced, direct-replacement design.
- Chamfered cross-drilled holes intended to limit stress cracking.
- Zinc-plated finish for an attractive face in open-center wheels.
- Vented, directional brake surface with an 8-stud hub.
Before you buy
Large four-wheel-drive trucks carry heavy front axle loads, so the brakes work hardest on long downhill runs and when pulling a trailer. Matching the rotor to the rest of the front brake system matters, because caliper size, pad shape and hub bolt pattern all need to agree with the new discs before any fitting begins.
Older Super Duty trucks often have worn hub faces and bearings that were never serviced with the original brakes. Clean the hub mounting surface and check for rust or pitting before installing the rotors. A rotor that sits against a rusted hub can run out and cause a pulsing pedal even when the disc itself is new.
Pads should be chosen for slotted and drilled rotors, since mismatched compounds can chip the friction edges or glaze the face. Keep the old rotors’ measurements on hand, and compare the new discs before fitting so the replacement sequence is clear.
