Overview
The Baer Brakes 6910303 is a left-side, 1-piece tall hat rotor with a slotted friction face. Its outside diameter is 12.000 inch and its nominal thickness is 1.100 inch. Baer offers it as a service part for select Baer Brake systems, and the slotted face is its defining surface feature.
Full cast construction, a vented body and curved vanes define the rotor. The casting is designed for rotor stability and resistance to distortion. The brake surface is directional, so the rotor is made for one side only and belongs on a left hub. Confirm fit for your vehicle’s year, model and trim before ordering.
Key features
- Slotted friction surface as the main face style
- Full cast single-piece body in cast iron
- Vented, directional brake surface for left-side use
- Tall hat profile with 2.228 inch overall height
- Five-hole stud pattern on a 4.75 inch circle
- Dynamic balance and curved cooling vanes
Slotted rotors and pad choice
Slots on a brake face give gas and water a path away from the pad contact area, which helps the surface stay consistent under repeated stops. The slot pattern is one part of the friction design, and the pad compound determines how the rotor wears and how quiet the brakes run. Matching pad material to the rotor and to how the vehicle is driven is the main decision after the rotor fits.
Slotted faces can show more visible wear than plain faces, so check the slot edges and the friction surface for cracking or heavy scoring at each pad change. Bedding in new pads and rotors gradually helps them transfer an even layer of friction material. If pulsation develops, measure runout and thickness before deciding whether the rotor should be replaced.
- Choose pads that suit your driving and load
- Bed in new pads following their recommended steps
- Inspect slot edges for cracks at each pad change

Vehicle fitment
This rotor is made for select Baer Brake systems, so confirm the application for your vehicle’s year, model and trim before ordering.
The rotor is left-side only and should not be fitted to a right hub. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Locate the rotor by its 2.781 inch center register and check that the hub register matches it. Measure the 2.228 inch overall height against calipers and clearance, and confirm the left-side orientation before tightening the wheel studs to the correct torque for your hub.
What’s included
One left-side replacement rotor, sold as each.
Not included: the ABS tone ring, so check your hub assembly for one.
