Overview
The Baer Brakes Big Claw 2142012 is a pair of rear drum-in-hat disc brake rotors for the 2021–2025 Jeep Wrangler JL and the 2020–2025 Jeep Gladiator JT, where the vehicle has a BR3, BR4 or BR5 brake code. The rotors are oversized and paired with new caliper brackets that reposition the calipers for the larger discs.
The rotors keep OE pad and hardware compatibility, so the kit is a direct bolt-on rear upgrade. The oversized rotors provide up to a 49 percent gain in braking effectiveness in independent third-party testing, and up to a 200-degree reduction in rotor temperature versus OE in extreme conditions.
Key features
- Oversized rotors deliver greater brake torque and leverage for stronger stopping power.
- Cross-drilled and slotted friction surface helps vent dust and gases for a steadier pedal feel.
- New OE-style brackets keep OE pad and hardware compatibility on the larger rotors.
- Curved, directional vanes move air to improve cooling and reduce brake fade.
- Direct bolt-on system with no brake bleeding required.
- Zinc-plated finish resists rust and corrosion behind open-spoke wheels.
Checking brake code basics
The brake code is the first thing to confirm before any rear rotor purchase, because it determines which rear brake hardware a vehicle uses. Once the code is confirmed, the rest of the job is mostly about clearance and hardware condition. Larger rotors need room inside the wheel, and the caliper brackets need to sit square on the axle before the rotor is set in place.
Rear brakes on a Jeep used off-road collect mud, sand and grit near the hub and caliper. Rinse the area after trail use, check the brake hose and fittings, and inspect the rotor surface for deep grooves. Avoid long, hard rear braking on steep descents, since that heat can wear pads and rotors faster than normal road use.

Vehicle fitment
Baer lists these rear rotors for the 2020–2025 Jeep Gladiator (JT) and the 2021–2025 Jeep Wrangler (JL), with a BR3, BR4 or BR5 brake code. The Wrangler applications read Jeep Wrangler JL and the Gladiator applications read Jeep Gladiator.
Other Jeep generations are not covered, and vehicles without a BR3, BR4 or BR5 brake code fall outside the listed fitment. Confirm your year, model and trim before ordering.
Installation notes
The rotors bolt on directly with no brake bleeding required. Baer recommends checking wheel clearance with its template for this system, including the spare tire and wheel, because fit into every wheel style cannot be guaranteed. Support the vehicle on stands before working on the rear brakes.
What’s included
A pair of oversized rear rotors and a pair of new caliper relocation brackets, sold as a set.
Not included: OE brake pads and hardware, which the brackets are designed to keep in use.
