Overview
The Baer Brakes Claw Performance Rotors, part number 55133-220, are a pair of rear slot-only, zinc-plated brake rotors for 2007–2020 Chevrolet and GMC 1500 trucks, Cadillac Escalade models and other GM applications. They are direct replacement rotors for the rear axle.
The slot-only friction surface lets gases and dust escape from between the pad and rotor, which Baer says supports a more consistent pedal and reduced brake fade. The zinc-plated finish gives open-center wheels a bright appearance, and the rotors are sold as a set.
Key features
- Slotted friction surface lets gases and dust escape between pad and rotor
- Enhanced vane structure and premium materials for cooling and durability
- Premium, mill balanced, direct replacement rotor
- Zinc-plated finish for a bright appearance in open-center wheels
- Slot and zinc finish complements the Baer 6T Truck and OffRoad front brake kits
- Floating, drum-in-hat rear design with a rust resistant coating
Before you buy
Rear brake rotors wear at a different rate than fronts, and on a truck the rear axle often carries less braking load, so the rear set may need attention on a different schedule than the pads up front. Check rear rotors for scoring, a raised lip at the outer edge, blue discoloration or pulsation through the pedal. Any of these signs means the rotor should be measured against its minimum thickness before the pads go back on.
Drum-in-hat rear rotors sit around the parking brake hardware on many setups, so inspect the hat section and the nearby parts during service. Rotors are usually replaced in pairs so both sides brake evenly. While the hub is off, check the wheel bearing and the ABS wiring, since a worn bearing or damaged tone ring is easier to correct at the same time.
- Rotor thickness measured against the minimum stamped on the casting
- Pads of matching friction material to the rotor
- Rear axle position matched before ordering
- Lug nut torque checked after the first drive

Installation notes
These rotors are direct bolt-on replacements that need no modifications. Brake work is safety-critical, so have a qualified technician install the rotors, check the pads and bed them in using the break-in steps that apply to the pads being fitted.
What’s included
A pair of direct replacement rotors, sold as a set.
Not included: brake pads and the ABS tone ring.
