Overview
The Baer Brakes 6929184 is a 12 inch, 1-piece right-side replacement brake rotor with a plain friction surface, made for select Baer Brake systems. It is a cast iron, vented, directional rotor with a 1.020 inch nominal thickness and a modified drum lip for early big bearing systems, so the drum-in-hat design is one of its defining traits.
Brake rotors take the clamping force of the caliper and shed heat, and this one is intended for owners who need a right-side swap in a Baer system. The casting uses a curved vane layout that aids cooling and dynamic balancing for smooth running. The rotor carries five studs on a 4.50 or 4.75 inch bolt circle and has a 2.780 inch center bore, so confirm both patterns against your hub before buying.
Key features
- Full cast, one-piece construction in cast iron
- Vented rotor with a curved vane design that Baer says aids cooling
- Directional brake surface built for the right side only
- Plain friction surface with no slots or drilling
- Drum in hat design with a modified drum lip for early big bearing systems
- It is dynamically balanced for vibration-free running.
- Performance grade type
Before you buy
Right-side rotors on big bearing hubs often get replaced in pairs, since worn friction surfaces and heat cracks usually show up on both sides at similar mileage. Buying the matching left-side rotor at the same time keeps braking even and avoids pulling. Check that the drum lip and bearing style on the new part match the hub before the old one comes off.
Cast iron rotors with a directional face should be fitted with the friction side facing the correct direction, and the vanes should be checked for debris from the old pad material. Pads are usually replaced at the same time, and bedding them in gives the rotor an even transfer layer.
- Measure thickness against the minimum stamped on the rotor
- Inspect the hat and drum lip for cracks
- Replace pads and rotors as a matched set

Vehicle fitment
It is made for select Baer Brake systems, and it suits early big bearing systems. Confirm your Baer system and hub setup before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor is directional and made for the right side only, so check the side marking against your hub before fitting, and keep the left-side part separate. Its drum lip is modified for early big bearing systems, so it is not a general swap for other bearing styles. A brake technician should confirm hub, bearing and caliper clearance before the rotor goes on, since the wrong bearing system can prevent a proper seat.
What’s included
One 1-piece right-side replacement rotor with a plain finish and the modified drum lip for early big bearing systems.
Not included: the left-side rotor for the opposite wheel, calipers, pads and hub hardware.
