Overview
The Baer Brakes 55073-020 is a set of two rear Claw performance rotors for listed 2002 to 2009 SUVs and crossovers from Buick, Chevrolet, GMC, Isuzu, Oldsmobile and Saab, plus the Chevrolet SSR for 2003 to 2006. Each rotor is one piece and fully cast, a direct replacement for the factory rear disc, with 6 studs on a 127 bolt hole circle diameter.
Baer Brakes presents the Claw rear rotor as a braking and appearance upgrade for these platforms. The cross-drilled and slotted friction face lets gas and dust escape from between pad and rotor, which the brand connects with a more even pedal and reduced fade. Chamfered holes are intended to reduce stress cracking, and the zinc-plated finish suits open center wheels.
Key features
- Cross-drilled and slotted rear friction surface
- Vane structure designed for cooling and durability.
- Premium, mill balanced direct replacement rotor
- Chamfered cross-drilled holes against stress cracking
- Zinc-plated finish suited to open center wheels
- Sold as a set; ABS tone ring not included
Choosing the right setup
This rotor fits several vehicles across different brands, so confirming the platform matters more than the rotor itself. Trailblazer, Envoy and Ascender models share related hubs, but engine size and axle details can differ by year. Check the year, model and engine on your vehicle against the entries before buying, and note the stud count and bolt hole circle diameter.
Rear rotors on these SUVs and crossovers are often replaced with pads at the same time. Pad compound should suit the vehicle’s weight and typical load, since heavy use can overheat plain pads. Clean the hub, check the wheel bearing for play, and inspect the parking brake, because a dragging rear brake can overheat a new rotor quickly.
After installation, drive gently and make several moderate stops to bed the pads. Recheck the lug nuts after the first few drives, as new rotors can settle slightly against the hub face.
