Overview
The Baer Brakes 6921145 is a right-side, 1-piece replacement brake rotor with slotted and drilled surfaces and a zinc-plated finish, sold individually. It measures 13.000 inch in outside diameter and 0.81 inch in nominal thickness, is vented, and has a 5 x 5.50 inch lug pattern. It is made for select Baer Brake systems and is directional, built for the right side of the vehicle.
The full cast iron body uses a curved vane design for cooling, and each rotor is dynamically balanced for vibration-free running. The design resists distortion and keeps the rotor stable. The 3 inch center hole and 3 inch overall height are the main dimensions to match against your hub.
Key features
- Slotted and drilled surface with a zinc-plated finish
- Curved vane design, which Baer says aids optimum cooling
- Directional rotor specific to the right side
- Full cast, one-piece construction in cast iron
- Dynamic balanced for vibration-free performance
- Drum-in-hat design
Slotted and drilled considerations
Slots and drilled holes help move gas, water and debris away from the friction face, which can be useful in wet or muddy conditions. Heavy braking produces more heat in any drilled rotor, and the holes can become crack starting points over time. Inspect the edges of each hole and slot at every pad change.
The zinc-plated finish protects the hub-side surfaces from rust during storage, but the friction face wears it off quickly. Expect some surface rust before the first stops and bed in the pads with a few moderate stops. Slotted and drilled faces tend to be harder on pads, so pad choice matters.
- Inspect drilled holes for cracking
- Check slot edges for raised lips
- Bed in pads with moderate stops

Vehicle fitment
Fitment is for select Baer Brake systems. Before fitting, check the axle side, 5 x 5.50 inch bolt pattern, 3 inch center hole and 13.000 inch diameter against your brake system and vehicle.
Do not use a left-side rotor in place of this right-side part. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Match the rotor to its side before installation, since it is directional. The 3 inch center hole has to seat on the hub, and the 5 x 5.50 inch lug pattern must match the wheel studs. Work on a supported vehicle and follow the brake system procedure for the pads and calipers.
What’s included
One right-side replacement rotor, sold individually.
Not included: ABS tone ring; this rotor does not include one.
