Overview
The Baer Brakes 6921103 is a 1-piece, slotted replacement brake rotor for the right side of select Baer Brake systems. It measures 12.000 inch outside diameter with a 1.020 inch nominal thickness, uses a 5 x 5.00 inch bolt pattern and a 2.780 inch center hole, and is sold as each.
Baer Brakes makes this rotor as a directional part, so right and left rotors are not interchangeable. It is a vented, full cast cast-iron design with a drum-in-hat layout, intended for owners replacing a worn right-side rotor in a compatible Baer system.
Key features
- Purpose-built full cast construction from premium materials
- Curved vane design for optimum cooling
- Engineered for rotor stability and resistance to distortion
- Dynamically balanced for vibration-free performance
- Slotted friction surface on a directional, right-side rotor
- Performance grade rotor in cast iron
Choosing a replacement rotor
A replacement brake rotor works as one half of a friction pair with the pads, so its surface finish and material should suit how the vehicle is driven. Cast iron rotors like this one handle heat well for everyday and towing use, but they need proper bedding in and regular inspection. A directional right-side rotor also has to sit square on the hub, and a rotor installed backward will wear unevenly.
Before ordering, measure the old rotor’s thickness and compare it with the minimum stamped on it. Check the hub face for rust or debris, since even small buildup can cause runout. Hub hardware and pads are often replaced at the same time, and new pads should be matched to the rotor’s surface.
- Measure the old rotor at several points around the face
- Clean the hub face and mounting surface before fitting
- Replace pads at the same time when the rotor is replaced

Vehicle fitment
It is designed for select Baer Brake systems. Confirm fit for your vehicle’s year, model and trim before ordering.
Match the right-side orientation, 5 x 5.00 inch bolt pattern and 2.780 inch center hole to your hub. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
This rotor is directional and specific to the right side, so it must not be installed on the left. Check that the 5 x 5.00 inch bolt pattern and 2.780 inch center hole match your hub before mounting. Because rotors are listed individually, a matching left-side rotor is needed if both sides are being replaced. The drum-in-hat design and the absence of an ABS tone ring should be checked against the hub you are working on.
What’s included
One right-side replacement rotor, sold as each.
Not included: the left-side rotor, brake pads, calipers and hub hardware.
