Overview
The Baer Brakes 6929089 is a right-side, 1-piece plain-finish replacement brake rotor measuring 12.000 inches across with a 1.020 inch nominal thickness. Baer makes it as a service part for select Baer Brake systems, and it is sold as a single rotor rather than a pair. Its cast iron body is vented and directional, with a 2.780 inch center hole and a 5 x 4.50 inch / 5 x 4.75 inch bolt circle. Fit is tied to the Baer system it serves.
The main difference from its slotted sibling, Baer part 6929090, is the friction face: this version has a plain surface with no grooves. Compare the finish and the axle side before choosing between the two, because the surface type is the deciding detail.
Key features
- Full cast, one-piece cast iron construction
- Curved vane design for optimum cooling
- Designed for rotor stability and resistance against distortion
- Dynamic balanced for vibration-free running
- Plain surface type on a vented, directional rotor
- Drum in hat design with a performance grade type
Plain face considerations
A plain friction face wears evenly and does not carry the grooves that slotted rotors use to shed debris. Many owners choose plain rotors for daily driving because they tend to run quietly with a wide range of pad compounds. Expect a short bedding procedure after installation, performed in a safe area with gradual stops, so the pad material transfers evenly to the rotor.
Plain rotors can develop a glazed or polished face when pads overheat, so watch for lost bite or pulsation under braking. Inspect the outer edge for a lip, which means the pads are cutting unevenly. A dial indicator can confirm runout before the rotor is mounted.
- Bed in new pads gradually
- Look for glazing or blue discoloration on the face
- Check the hub face for rust or debris
- Tighten wheel lugs in a star pattern after the first drive

Vehicle fitment
It is a replacement for select Baer Brake systems, so verify the system, the right-side position and the bolt circle against your existing parts before purchase. Confirm the fit for your vehicle’s year, model and trim before ordering.
A left-side application needs its own rotor, and the slotted version of this size is a separate product. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the rotor is directional and specific to the right side, fit it only to the right hub and buy a separate left rotor for the other side. Check the 5 x 4.50 inch / 5 x 4.75 inch bolt circle and 2.780 inch center hole against the hub. Brake rotors affect stopping performance, so have a qualified technician inspect the finished installation.
What’s included
One right-side plain-finish rotor, sold as each.
Not included: the left-side rotor and other Baer Brake system parts.
