Overview
The Baer Brakes 6919104 is a left-side, one-piece replacement brake rotor for select Baer Brake systems. Its friction face is both slotted and drilled and carries a zinc-plated finish. The rotor measures 12.000 inches in outside diameter and 1.020 inches nominal thickness, with an overall height of 2.406 inches.
Made of cast iron in a full cast, one-piece build, it is performance grade. Curved vanes aid cooling, and the rotor is dynamically balanced. It has a drum in hat and is directional, made specifically for the left side, and sold individually.
Key features
- Slotted and drilled friction face
- Zinc-plated finish
- Curved vane design for cooling
- Full cast, one-piece cast iron construction
- Dynamically balanced
- Drum in hat listed
- Directional design for the left side
Drum in hat considerations
The drum in hat means the rotor carries a parking brake drum surface inside the hat, so the parking brake shoes and hardware are part of the job. Check the drum surface for scoring and the shoes for wear before fitting the new rotor, because a rough drum surface can shorten shoe life and reduce parking hold.
Zinc plating protects the rotor body from surface rust during storage, but it is a coating rather than a permanent barrier. Clean any light rust from the hub face and bolt holes, and avoid high-pressure washing near fresh finish. Drilled holes also collect grit, so check them for cracks after hard use.
- Inspect the drum and shoes for scoring
- Clean the hub face before seating the rotor

Vehicle fitment
It is made for select Baer Brake systems. Check fit against your vehicle’s year, model and trim before buying, and compare the 5 x 4.50 in bolt pattern and 2.406 in overall height with your hub.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Inspect the drilled holes and zinc-plated surface for damage when the rotor arrives, since the finish is the protective layer. The drum in hat means the parking brake area must be checked before the rotor goes on. Confirm it is the left unit, and verify runout with a dial indicator before road use.
What’s included
A single left-side rotor, sold individually.
Not included: brake pads, calipers and mounting hardware.
