Overview
The Baer Brakes 6910306 is a left-side, one-piece tall hat replacement brake rotor with a slotted, drilled and zinc-plated surface. It is listed at 12.000 inch outside diameter and 1.100 inch nominal thickness, and it is intended for select Baer Brake systems. Its part number, 6910306, is the reference to use when ordering the correct side.
This vented cast iron rotor uses a full-cast, single-piece body with a tall hat that bolts to five studs on a 4.75 inch circle, centered by a 2.781 inch center bore. Because the rotor is directional, the left-side version belongs only on the left hub. The right side requires a separate rotor, which is not part of this item.
Key features
- One-piece full-cast construction with a tall hat section.
- Slotted, drilled and zinc-plated surface.
- Curved vane design, which Baer Brakes describes as optimum cooling.
- Dynamic balanced for vibration-free performance.
- Directional brake surface built for the left side only.
- Premium casting materials support rotor stability and resistance to distortion.
Tall hat rotor basics
A tall hat rotor raises the braking surface away from the hub so the friction face clears the wheel and caliper. The hat and center bore set how the rotor sits on the hub, so the center bore and stud pattern must both match before the rotor is bolted on. Any rust or debris on the hub face can cause the rotor to sit off center and produce vibration.
Tall hat rotors are often replaced with new hub hardware and fresh wheel studs, because the mounting faces carry the braking load. After fitting, tighten the wheel fasteners in a star pattern and recheck them after the first few drives. Inspect the hat for cracks around the stud holes and watch for a lip on the outer edge of the friction face.
- Confirm the center bore and stud pattern before fitting
- Check hat height against caliper and wheel clearance
- Re-check wheel fasteners after the first few drives

It is a replacement for select Baer Brake systems. Confirm fit for your vehicle’s year, model and trim before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor is directional, so confirm the left-side marking against the hub before mounting. Check that the 5 x 4.75 inch pattern and 2.781 inch center bore match the hub you are replacing. The overall height is 2.228, so check clearance inside the wheel as well.
What’s included
A single left-side replacement rotor, sold as each.
Not included: the right-side rotor, which is a separate item.
