Overview
The Baer Brakes 6910959 is a 15 inch, one-piece, left-side slotted replacement brake rotor for select Baer Brake systems. It uses a 6 hole pattern on a 5.50 inch bolt circle with a 3.094 inch center hole.
Rotors slow the wheel when brake pads press against them. This full cast iron rotor is vented, measures 1.18 inches nominal thickness and 2.177 inches overall height, and has curved vanes that Baer Brakes says support cooling. The slots are the only surface treatment listed.
The rotor is directional, so it is made for the left side only. Dynamic balance helps limit vibration, which is most noticeable at highway speeds where an unbalanced wheel shows up first.
Key features
- One-piece full cast construction
- Slotted surface on a vented cast iron rotor
- Left-side directional design
- Curved vanes intended for cooling
- Dynamic balanced to limit vibration
- Stability and distortion resistance built into the design
- Six-hole pattern on a 5.50 in bolt circle
- Performance grade type with emission code 6
Center bore and hub fit
The center bore keeps a rotor centered on the hub, so a bore that is too tight or too loose can cause vibration even when the bolt pattern matches. Measure the hub pilot diameter before buying, and remember that the center bore is a fit point rather than a fastening point. The lug holes carry the clamping load, while the center bore sets the rotor on true.
Before mounting, clean any rust from the hub pilot and the back face of the rotor. A thin layer of rust or paint can hold the rotor slightly off center. If the bore needs relieving, take small amounts of material off carefully and never force the rotor over a hub that is too large. A centered rotor reduces runout, which keeps pulsation out of the brake pedal.
- Measure the hub pilot before ordering
- Clean rust from the pilot and rotor back
- Mount the rotor without forcing it
- Check runout after the first few drives

Vehicle fitment
It is made for select Baer Brake systems. Confirm the hub bolt pattern and center bore against your vehicle before fitting.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Only the left hub takes this rotor, because the design is directional. The ABS tone ring is not included, so check how your hub is set up beforehand. Improper brake fitting can compromise braking, so a trained brake technician should complete the install.
What’s included
One left-side one-piece slotted rotor.
Not included: ABS tone ring.
