Overview
The Baer Brakes 6910986 is a 1-piece, left-side short hat replacement brake rotor with a slotted, drilled and zinc-plated surface, a 13.000 inch outside diameter and a 0.810 inch nominal thickness. It is a vented cast iron rotor with five lugs on a 4.50 inch bolt circle and no drum in the hat.
The curved vanes are designed to aid cooling, and the rotor is dynamically balanced. It is directional and specific to the left side. Confirm the brake system before buying, since it is made for select Baer Brake systems.
Key features
- Slotted, drilled and zinc-plated friction face
- Short hat design with no drum in the hat
- Curved vane design intended for cooling
- Dynamically balanced rotor
- Directional, left-side rotor
- Full cast, one-piece cast iron construction
- Five-lug pattern on a 4.50 inch bolt circle
Matching a 4.50 inch hub
A 4.50 inch bolt circle is a specific pattern, so the hub bolt holes must match exactly before the rotor is considered a fit. Measure from the center of one lug hole across to the opposite hole, or compare with the old rotor’s hub face. Center-bore and register alignment matter too, since an off-center rotor can cause vibration.
Short hat rotors sit closer to the hub, which changes how the caliper and bracket clear the assembly. Check caliper bracket bolts and pad clearance after mounting, and inspect the slotted drilled face for hairline cracks as it wears. Replace rotor and pads together when wear is uneven or the surface shows heat damage. Use new lug nuts or studs if the originals show thread damage.

Vehicle fitment
The brake system defines where this rotor belongs, since it is made for select Baer Brake systems. Confirm fit for your vehicle’s year, model and trim before ordering.
A short hat left rotor with a 4.50 inch bolt circle is not a general fit for every vehicle with five lugs. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor is directional and specific to the left side, so confirm the side before fitting. Because the bolt circle is 4.50 inch, compare it with the existing hub before ordering.
What’s included
One left-side short hat replacement rotor, sold as Each.
Not included: the right-side rotor, which must be purchased separately.
