Overview
The Baer Brakes 6910309 is a left-side, 15-inch, 2-piece slotted replacement brake rotor ring for select Baer Brake systems. It has a 1.25 inch nominal thickness and a 12 x 9.45 inch mounting bolt pattern, and it is sold as each.
Two-piece rings bolt to a separate hat, so the ring’s bolt pattern and the hat must agree. This ring is vented cast iron with a slotted face, and it has no drilled holes or zinc plating. Use the dimensions to compare diameter, thickness and bolt pattern with the hub you are servicing.
Key features
- Slotted friction face
- Two-piece construction
- Vented cast iron ring
- Directional design for the left side
- Curved vane design intended for cooling
- Balanced for vibration-free performance
Matching ring and hat
Matching a two-piece ring to its hat is the key step, because the hat sets the mounting face, bearing position and wheel studs. Confirm that the bolt holes, the bolt circle and the hat’s thread condition all agree before the ring is mounted. A mismatch can cause vibration, uneven clamping and premature wear.
Slotted rings clear pad debris and water, but the slot ends can crack after heavy heat cycling, so inspect the faces during pad changes. Vented rings should be cleaned of packed debris from the vanes. Keep the caliper bracket clear of the ring edge and check clearance once the ring is fitted.
- Check the hat thread condition
- Inspect slot ends for cracks
- Clean vent passages during pad service
