Overview
The Baer Brakes 6910797 is a left-side, 1-piece slotted replacement rotor with a 13.250 inch outside diameter and .550 inch nominal thickness. Baer makes it for select Baer brake systems, and the rotor is directional, meaning it is built for the left side only. It is a non-vented, solid cast iron disc.
The slotted finish cuts across the friction face of the disc. Baer Brakes markets the rotor as performance grade and offers it one per part number, so match it with a right-side rotor when both sides need replacing. Its center register is listed at 2.783 inch, which should match your hub.
Measure the five-stud pattern on a 4.50 inch bolt circle and the 1.967 inch overall height against your existing rotor before fitting.
Key features
- Left-side directional rotor
- Slotted surface with a non-vented, solid disc design
- One-piece full cast construction in cast iron
- Performance grade rotor for select Baer brake systems
- Dynamically balanced for smooth running
- Five studs on a 4.50 inch bolt circle
Braking behavior and fitting care
Brake rotors work with the pads to turn motion into heat, so the disc has to stay flat, true and evenly worn to keep the pedal steady. Slotted faces help clear pad dust, water and gas that can build up between the pad and disc during hard stops, although they do not replace good pad material or proper bedding. On a solid, non-vented disc like this one, heat stays in the casting, so repeated hard use on steep grades or trails can fade braking if the pads and fluid are not suited to the work.
Rotors are usually changed together with pads. The hub face should be cleaned of rust and old debris before the new rotor goes on, since a dirty mounting surface can cause runout and vibration. Before fitting, check that the new disc sits flat against the hub and that the center register seats without forcing. After the first few drives, bed the pads in gently and re-check the wheel bolts.
- Clean the hub face and lug studs before mounting
- Replace pads when rotors are changed
- Check the brake fluid condition
- Inspect for cracks, deep grooves and a lip at the outer edge
- Re-check lug nut torque after the first drives

Vehicle fitment
Confirm your vehicle’s year, model and trim before ordering. Because the rotor is directional, the side must match the wheel.
Installation notes
Confirm the side before installing, since this rotor is directional and specific to the left. Brake repairs are best left to a qualified technician, who will also check the hub surface and fasteners.
What’s included
One left-side 1-piece slotted replacement rotor, sold as each.
Not included: a right-side rotor, which is needed separately if both sides are being replaced.
