Overview
The 6910043 is a 1-piece plain finish replacement brake rotor for the left side, with a 13.000 in outside diameter and 1.100 in nominal thickness. It is made for select Baer Brake systems. The full cast, vented cast iron rotor is sold as each and is built as a left-hand part because its braking surface is directional.
The surface is plain rather than slotted. The casting is made from premium materials, with a curved vane design, engineered for stability against distortion, and dynamically balanced for smooth running. The center hole of 2.799 in and overall height of 1.717 in are useful for checking fit against your hub.
Key features
- Plain, unslotted friction surface
- Curved vane design intended for cooling
- Full cast, one-piece construction
- Directional brake surface, left axle side
- Dynamic balanced for vibration free performance
- Vented rotor in cast iron
- Performance grade type
- 2.781 in register for the hub
Plain versus slotted
A plain friction surface has no grooves, so it presents a continuous face to the pad. Many drivers choose a plain rotor for street use, where the pad stays evenly bedded and dust and gas buildup are less of a concern. The tradeoff is that a plain face gives less channel for debris and water to escape, which matters more in mud, sand, or repeated hard stops.
When choosing between plain and slotted rotors, consider how the vehicle is used, the pad compound in service, and the other components on the axle. Pads, calipers, and brake lines are often inspected or replaced at the same time as rotors, so budget for those parts in the same service interval.
- Plain surfaces suit street-focused use
- Slotted surfaces help clear debris under hard use
- Match the pad compound to the rotor surface

Vehicle fitment
Left-side only: the rotor is made for the left hub and is not a right-side replacement. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because this rotor is directional and side-specific, make sure the left-hand part goes on the left hub. Confirm the 2.781 in register and five-stud bolt pattern against the hub before mounting. A brake fault can cost stopping power, so a qualified technician should complete and verify the work.
What’s included
One left-side plain finish replacement rotor, sold as each.
Not included: Hub, bearings, caliper, pads and mounting hardware are not part of this rotor.
