Overview
The Baer Brakes 05703-020 is a set of two front Claw performance rotors for the 2006–2010 Hummer H3 with 4WD or AWD and the 2009–2010 Hummer H3T with 4WD. They are sold as direct replacement rotors, so the design is meant to match the original front rotor position.
The slots and drilled holes let gases and dust escape from between the pad and rotor, which supports a more consistent pedal feel and less brake fade. Each rotor is one-piece full cast iron with a zinc-plated finish that looks bright when seen through open-center wheels. The 315 outside diameter, 70 overall height and 140 bolt circle can be checked against your current front rotors before ordering.
Key features
- Slotted and cross-drilled friction surface to move gases and dust away from the pad face
- Enhanced vane structure that Baer describes for cooling and durability
- Mill balanced, premium direct replacement rotor design
- Chamfered cross-drilled holes that Baer says reduce stress cracking
- Zinc-plated finish that Baer describes as bright in open-center wheels
Before you buy
Front rotors on a heavy SUV or truck take most of the braking load, so their condition shapes how the whole system feels. Before replacing them, inspect the old rotors for scoring deep enough to catch a fingernail, blue discoloration from overheating, and thickness close to the minimum stamped on the rotor. Uneven thickness often shows up as a pulsing pedal under light braking.
Pads are usually replaced at the same time as rotors. Pads designed for performance use suit slotted and drilled faces better than worn, glazed pads. Hub bearings, caliper slide pins and brake hoses are worth checking while the wheel is off, because a fresh rotor will not correct a sticking caliper.
- Check wheel bearing play before installing new rotors
- Clean the hub face so the rotor sits flat
- Replace worn pads together with the rotors

Vehicle fitment
It fits the 2006–2010 Hummer H3 with 4WD or AWD drive and the 2009–2010 Hummer H3T with 4WD drive.
The listed fitment does not cover the Hummer H2 or Hummer H3 and H3T models outside these years and drive types. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The brake surface is directional, so check the rotation marking on each rotor and fit the pair to match before reassembly. Bed in new pads as the pad maker directs. Brake work on this truck should only be done by someone comfortable with hub and caliper service.
What’s included
The set contains two front rotors, sold as a pair.
Not included: brake pads, which are separate parts.
