Overview
The Baer Brakes 6910156 is a left-side, 2-piece replacement brake rotor with a slotted, drilled and zinc-plated surface, made to suit select Baer Brake systems. It measures 12.000 inch across with a 0.81 inch nominal thickness and a 12-bolt pattern on a 7.5 inch bolt circle. Match it to your Baer system by caliper, hub and bolt pattern, and confirm fit for your vehicle’s year, model and trim before ordering.
Because the rotor is directional, it is built only for the left side of the vehicle and should not be installed on the right. The brake surface is vented, and the cast iron ring uses a curved vane layout meant to help cooling. Rotors are sold individually, so buy one for each position you are replacing.
Key features
- Two-piece construction with a cast iron rotor ring
- Slotted and drilled friction surface with a zinc-plated finish
- Curved vane design intended to improve cooling
- Directional brake surface made for the left side only
- Vented rotor style
- Dynamic balanced for vibration-free running
- Engineered for rotor stability and resistance to distortion
Signs the rotor is worn
Brake rotors wear with every stop, and the friction surface gradually loses thickness over its service life. Slots and drilled holes help move water, gas and debris away from the pad face, but they also give the pad edges more places to catch and wear the surface. For that reason, check the face regularly for deep grooves, blue heat marks and a raised lip at the outer edge.
Pulsation through the pedal or a steering wheel shake under braking often points to uneven thickness or runout, while a grinding sound usually means the pads are worn through. Measure thickness with a micrometer and compare it to the minimum thickness stamped on the rotor or published for your vehicle before reusing it. Replace the pads at the same time so the new rotor is not paired with worn friction material.
- Deep grooves or scoring across the friction face
- Blue or discolored patches from overheating
- Pedal pulsation or steering wheel vibration when braking

Vehicle fitment
It suits select Baer Brake systems, so compare the caliper, hub and 12-bolt, 7.5 inch bolt circle pattern to your setup before buying.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The left-side direction matters: a directional rotor installed on the wrong side will not brake as designed. The ABS tone ring is not included, so reuse your existing ring only if your system already requires one. Bed in new pads and rotors gradually before heavy braking.
What’s included
One left-side rotor ring, sold individually.
Not included: ABS tone ring.
