Overview
The Baer Brakes 6919185 is a left-side, 12-inch slotted replacement brake rotor for select Baer Brake systems, including early Big Bearing Systems. It is a one-piece, vented cast iron rotor with a drum-in-hat design.
It is a performance rotor with a curved vane pattern for cooling, designed to resist distortion. Each rotor is dynamically balanced for vibration-free running. It is directional and made for the left side only, and each part number covers a single rotor.
Key features
- Left-side directional rotor, made for the left side of the vehicle only
- Slotted surface finish
- Curved vane design for optimum cooling
- Dynamic balanced for vibration-free performance
- Full cast, one-piece construction in cast iron
- Drum-in-hat design with a modified drum lip for early Big Bearing Systems
Before the rotor goes on
A slotted rotor is designed to shed water, dust and gas from the friction surface, which can help the pads contact clean metal during hard braking. Slots can also wear pads faster in some uses, so pad choice matters. Look at the surface for cracks around the slots, and check the edges for lipping that can hold pad dust.
Because this is a directional rotor, orientation matters as much as fit. Mount it with the surface facing the correct direction for the left side, and confirm the hub face is clean and free of rust before tightening the lug nuts. Bed in new pads and rotors gradually to avoid glazing, and recheck lug nut torque after the first few drives on a new setup. Keep the old parts until the new setup has been road tested and inspected.

Vehicle fitment
It is made for select Baer Brake systems, specifically early Big Bearing Systems. Confirm your vehicle’s year, model and trim before ordering, and check the bearing setup against the big bearing configuration.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the rotor is directional, install it only on the left side and keep its orientation correct. Each part number is one rotor, so a matched pair needs a separate right-side purchase. Confirm the hub and bearing setup matches the Big Bearing Systems this rotor is machined for before fitting. Brake rotors are safety parts, so a qualified technician should check fit before driving.
What’s included
One left-side replacement rotor per part number.
Not included: The right-side rotor and an ABS tone ring are not included.
