Overview
The Baer Brakes 6910045 is a left-side, 1-piece slotted replacement brake rotor measuring 13.000 in outside diameter and 1.100 in nominal thickness, made for certain Baer Track4, SS4 and other Baer Brake systems. It is a full cast, vented short hat rotor in cast iron, sold as each and designed for the left side of the vehicle only.
The rotor is a purpose built casting from premium materials, with a curved vane layout for cooling, designed for rotor stability and resistance to distortion, and dynamically balanced for vibration free running. Because the brake surface is directional, the part is made specifically for the left hub.
Key features
- Slotted friction surface on a 1-piece replacement rotor
- Curved vane design for optimum cooling
- Full cast, one-piece construction in cast iron
- Directional brake surface made for the left side
- Dynamic balanced for vibration free performance
- Short hat design with a 2.781 in register
- Performance grade type, vented rotor
Before you buy
Left and right rotors are not interchangeable, and a directional rotor only works correctly on the side it was made for. Before ordering, identify the hub side, the wheel bolt pattern and the register diameter on the vehicle, then compare those with the Baer system the rotor is intended for. Because this is a full cast rotor, the hat and friction surface form one unit, so surface wear is usually handled by replacing the rotor rather than by machining it.
Brake rotors are normally replaced in pairs on the same axle, since mixing new and worn friction surfaces can cause uneven pad contact and noise. Inspect the caliper slides and pad hardware at the same time, and clean rust from the hub face and register before mounting so the rotor seats flat against the hub.
- Clean the hub face and register before mounting
- Inspect caliper slides and pad hardware while the wheel is off
- Bed in new pads with a gradual stop routine

Vehicle fitment
This is a left-side rotor only and is not made for right-side hubs. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor is directional and side-specific, so the left-hand part belongs on the left hub only. Check the 2.781 in register and the 5 x 4.50 in bolt pattern against the hub before mounting. Brake components affect stopping, so have a qualified technician confirm the installation and wheel torque.
What’s included
One left-side replacement brake rotor, sold as each.
Not included: Hub, bearings, caliper, brake pads and mounting hardware are not part of this rotor.
