Overview
The Baer Brakes 6921100 is a 2-piece right-side rotor ring with slotted, drilled and zinc-plated friction faces, used in select Baer Brake systems. It measures 14.000 inch outside diameter and 1.250 inch nominal thickness, and it mounts on a 12 x 8.320 inch bolt circle.
The two-piece design means the friction ring is a separate component from its mounting hat. The rotor is directional, so the right-side ring belongs only on the right side. The castings are purpose built from premium materials, with curved vanes for cooling.
Key features
- Two-piece construction with a separate friction ring
- Slotted, drilled and zinc-plated surface
- Curved vane design for cooling
- Directional brake surface for right-side use
- Dynamically balanced for smooth running
- Performance grade cast iron
- Designed for rotor stability and distortion resistance
Two-piece rotor maintenance
On a two-piece rotor, the friction ring and mounting hat can wear or loosen at different rates, so inspect the attachment points each time the wheel comes off. Look for cracks around the drilled holes, which are a common stress point, and for any movement between ring and hat. Tighten fasteners to the value your vehicle requires, and recheck them after the first few drives.
Drilled and slotted surfaces help clear gas and water, but they can also accelerate pad wear in some driving conditions. Pads with a compound suited to the rotor’s surface tend to last longer. Coatings on the ring should be inspected for flaking, since rust under the coating can weaken the attachment area.
- Inspect ring-to-hat contact at every brake service
- Check drilled holes for cracks or elongation
- Recheck fasteners after the first few drives

Vehicle fitment
It is intended for select Baer Brake systems. Confirm the hub and bolt pattern your vehicle requires before ordering.
The 12 x 8.320 inch bolt circle and right-side orientation are the key checks against your hub. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Two-piece rotors depend on a separate mounting hat, so check how the ring attaches to your existing hub before fitting. The rotor is directional and the right-side ring cannot go on the left. Left-side work needs its own ring, since rotors are listed individually.
What’s included
One right-side two-piece rotor ring, sold as each.
Not included: the left-side ring, brake pads and calipers.
