Overview
The Baer Brakes 55133-020 is a rear Claw performance drum-in-hat rotor set. It fits the Cadillac Escalade, Escalade ESV and EXT, Chevrolet Avalanche, Silverado 1500, Suburban and Tahoe, and GMC Sierra 1500, Yukon and Yukon XL, across the model years covered below.
The rotor is floating and drum-in-hat, with a cross-drilled and slotted face that clears gases and dust from the pad and rotor. The design supports steadier pedal feel and less brake fade. The zinc plating and straight vent design keep the look bright behind open center wheels.
Key features
- Slotted and cross-drilled face moves gases and dust out from under the pads.
- Improved vane structure aimed at better cooling and durability.
- Mill balanced premium rotor, designed as a direct replacement.
- Chamfered cross-drilled holes to help prevent stress cracking.
- Zinc-plated finish for appearance in open center wheels.
- Rust resistant coating and a floating drum-in-hat design.
Before you buy
Rear rotors on full-size trucks and SUVs carry heavy loads and, when towing, sustained heat. A drum-in-hat rotor adds a hat section that bolts to the hub and carries the braking surface, so the fit between hat and hub matters as much as the friction face. Before ordering, measure the existing rotor’s outside diameter, overall height and hub bore, and compare them with the new part.
Pads are usually replaced at the same service. New pads bed in best against new rotors, and worn pads can leave ridges that shorten rotor life. Parking brake hardware on drum-in-hat rears may also need inspection, since the hat section sits close to the shoes and cable.
- Check hub and bearing condition before fitting
- Clean the hub face and hat mounting surface
- Replace rear pads on the same axle at the same time
- Bed in new pads using the recommended procedure
- Re-check lug nut tightness after the first few stops

Installation notes
Bearings and races are not included, so confirm that your hub bearings and races are serviceable before fitting. Because this is a drum-in-hat design, check that the hat section seats fully against the hub. Brake work carries real safety risk, so a qualified shop is the safer choice for many owners.
