Overview
The Baer Brakes 6910327 is a 2-piece slotted replacement rotor ring for the left side of select Baer Brake systems. The ring has a 12.000 Inch outside diameter, a 1.100 Inch nominal thickness and 12 mounting bolt holes on a 7.500 Inch bolt circle.
Baer Brakes casts the ring from cast iron in a vented design with a slotted surface. It is directional, so it belongs on the left hub, and a right-side ring needs its own part number.
Key features
- Slotted friction surface.
- Vented cast iron two-piece construction.
- Curved vane design that Baer Brakes links to optimum cooling.
- Dynamic balanced for vibration-free running.
- Directional surface matched to the left side only.
- Twelve mounting bolt holes on a 7.500 Inch bolt circle.
Vented ring maintenance
Vented rings have two friction faces separated by cooling vanes, which helps air move through the ring during repeated stops. Check the vanes for debris packing and for cracks that run toward the outer edge. Keep the cooling passages clear after off-road use, when mud and gravel can collect.
Slotted faces help clear pad residue and gas during hard braking, but the slots also trap grit. Inspect the surface for uneven wear, grooves that have deepened, and hot spots that leave blue marks. Let the brakes cool before checking the ring, and bed in new pads carefully after installation. Two-piece rings need the hat and fasteners checked as part of the same job.
- Clear debris from vanes after mud runs
- Check the hat for cracking around bolt holes
- Replace pads together with the ring
