Overview
The Baer Brakes 6929234 is a right-side, one-piece replacement brake rotor with a plain friction surface, 12 inch outside diameter and 1.02 inch nominal thickness. It is built for select Baer Brake systems and carries a modified drum lip machined for early Big Bearing systems. Part number 6929234 identifies this plain-surface version.
Plain rotors have no slots or drilled holes and no zinc plating, which sets this part apart from slotted or drilled finishes. It is vented, cast iron, and performance grade. The rotor is directional and made for the right side of the vehicle. Rotors are sold individually.
Key features
- Plain friction surface with no slots or drilled holes
- Full cast, one-piece body made from cast iron
- Vented design with curved vanes for optimum cooling
- Drum in hat with a modified drum lip for early Big Bearing systems
- Dynamic balance for vibration-free performance
- Designed to resist distortion and keep its shape under use
- Directional right-side design with no ABS tone ring
Plain versus slotted surfaces
Plain friction surfaces are simpler to machine and tend to keep pad contact uniform. Without slots or drilled holes, there are no edges for debris to catch on, so the surface stays smooth in ordinary street use. A plain rotor suits regular street driving where a simple friction face is preferred and pad choice is set by everyday use.
When fitting a plain rotor, keep the hat, hub and lug studs clean and inspect them for damage before torquing. Check for runout with a dial indicator if pulsation appears after installation, because a wobbling rotor can cause pedal pulsation even when the new part is correct. Replace pads with a matched friction material and bed them in.
- Clean the hub face before installing
- Check for runout if the pedal pulsates
- Use new hardware when old studs are worn
- Replace pads when the rotor is replaced

Vehicle fitment
This rotor is designed for select Baer Brake systems. Because the drum lip is shaped for early Big Bearing hubs, hub design decides fit rather than model year.
Installation notes
Only the right side applies to this rotor, so fit it to the right hub. Verify the early Big Bearing hub design before installation, because the modified drum lip is machined for those hubs and not for others. Have a qualified technician handle the install, since brake parts affect stopping performance.
What’s included
One right-side plain-surface replacement rotor, sold individually.
