Overview
The Baer Brakes 6921106 is a right-side, 1-piece replacement brake rotor with a 12.000 inch outside diameter, made for select Baer Brake systems. It is a slotted, drilled and zinc-plated cast iron rotor with a drum-in-hat design.
Baer Brakes marks this rotor as directional and tied to one side, so the right-hand version is the only one described here. The 2.780 inch center hole and 2.406 inch overall height are the main dimensions to match against an existing rotor. No vehicle is named for this part, so the Baer system it belongs to needs confirming first.
Key features
- Full cast, one-piece construction in cast iron
- Curved vane pattern that Baer Brakes says is meant for cooling
- Slotted, drilled and zinc-plated friction surface
- Dynamic balancing for smooth running without vibration
- Drum-in-hat configuration
- Engineered for rotor stability and resistance to distortion
Drum-in-hat rotors explained
A drum-in-hat rotor combines a disc friction surface with a hat section that houses the parking brake shoes. That combined design saves space and lets one part handle both service and parking braking, but it also means the hat area is part of the brake assembly that needs attention. Dust, road grime and worn shoe material collect inside the hat over time, so it should be inspected whenever the rotor comes off.
When choosing a replacement, match the drum-in-hat design to the existing hub so the hat and shoes line up with the parking brake hardware. The rotor’s outer diameter, center hole and overall height all affect how it seats, so compare them with the old part before ordering. Many people replace the pads, the parking brake shoes and the hardware at the same time, which helps the new rotor run true from the first stop. After installation, check that the parking brake works and adjust it if needed, then bed in the new brakes gently on a quiet road before heavy use.
- Clean dust and debris from inside the hat during each rotor change
- Check the parking brake shoes for wear or contamination
- Confirm the center hole and overall height match the old part

Vehicle fitment
It is tied to select Baer Brake systems rather than a make, model or year range. Sold as each, so a matching left rotor is a separate item.
No named vehicle is tied to this rotor. Confirm your vehicle’s year, model and trim before ordering, and confirm that the Baer system matches the rotor you have.
Installation notes
Fit this directional rotor only on the right-hand hub. Compare its 2.406 inch overall height and 2.780 inch center hole with the rotor you are replacing before fitting. A qualified brake technician should handle the swap, since the drum-in-hat design requires careful measurement.
What’s included
The package holds one right-hand rotor, sold as each.
Not included: an ABS tone ring, because the ABS tone ring entry reads No.
