Overview
The Baer Brakes 6910145 is a left-side, one-piece plain-surface replacement rotor for select Baer Brake systems. It is full cast from cast iron, 12.000 inch in outside diameter and 1.02 inch thick, with five studs on a 4.75 inch bolt circle. No vehicle fitment is listed, so confirm the match with Baer before installing.
This is a directional part for the left side only. It is vented, has a 2.78 inch center hole and an overall height of 2.406 inch, and includes a drum in hat. It is sold individually.

Care after installation
Once installed, a rotor needs little routine care beyond regular inspection. Keep road salt, mud and grease away from the friction face, since oily residue can reduce pad bite and cause uneven braking. Wash the wheels periodically, and expect light surface rust after rain on a new cast iron disc, which should wear off after the first few stops.
Inspect the rotor at every tire rotation or pad change. Look for scoring, heat discoloration, cracks running from the center bore and any sign that the outer edge has built a lip. A rotor replaced because of damage rather than wear alone often points to a problem with the caliper, slide pins or hub, which should be checked at the same time.
- Keep grease and brake fluid off the friction face
- Check slide pins when pads are changed
- Replace a cracked rotor rather than reusing it

Vehicle fitment
The rotor is built for select Baer Brake systems, so verify the hub, caliper and register dimensions against your setup before fitting it.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Confirm the 2.78 inch center hole matches the hub register so the rotor sits flat when bolted on. The rotor is for the left hub only. The ABS tone ring is not included, so keep your existing ring if the hub uses one.
