Overview
The Baer Brakes 6910102 is a left-side, one-piece short hat replacement brake rotor with a slotted, drilled and zinc-plated surface. It measures 12 inch in outside diameter and 0.81 inch in nominal thickness, with an overall height of 1.988 inch. The full cast vented cast iron rotor is made for select Baer Brake systems.
Baer places this rotor in its Performance grade, and it has no drum in the hat. The 2.783 inch center hole serves as the hub register, centering the rotor on the hub. Confirm compatibility with your Baer setup before installing.
Key features
- Slotted, drilled and zinc-plated surface
- Short hat with one-piece full cast body
- 2.783 inch register center hole
- Curved vanes intended for cooling
- Dynamically balanced body
- Directional brake surface for the left side
Hub register and centering
The center hole of a short hat rotor sits over the hub register, so it locates the rotor before the lug studs take the load. A correct register fit keeps runout low and prevents vibration. Before mounting, wipe the hub face clean, remove rust or corrosion, and confirm the rotor sits flat against the hub without rocking.
Short hat rotors bolt to a hub with a shallow hat shape and no drum, so caliper bracket clearance matters. Check that the caliper and pads fit without rubbing the hat wall. Lug studs should be in good condition, and wheel nuts tightened in a star pattern to the torque the vehicle requires.
- Inspect lug studs for thread damage
- Check the hub for burrs or corrosion
- Recheck lug torque after the first few drives

Vehicle fitment
Compare hub size, lug count and center bore against your vehicle’s year, model and trim before choosing this rotor.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Since the rotor is directional, the left-side part must be installed on the left of the vehicle. Confirm the 2.783 inch center hole matches the hub register before fitting, because the short hat depends on it for centering. A qualified technician should check the install.
