Overview
The Baer Brakes 4401011B-2 is a Black 6T front brake system for Jeep Wrangler JK and JL and Jeep Gladiator JT vehicles with factory spindles and hubs. It combines a 6-piston, 6T caliper with a 13.5 inch vented, slotted rotor. It covers the 2007–2018 Jeep Wrangler JK, 2018–2025 Jeep Wrangler JL and 2020–2025 Jeep Gladiator JT.
The caliper is a 2-piece design machined from forged or billet aluminum in Phoenix, Az, with a powder coated finish. Stainless pistons and abutments carry noise suppression clips, and the staggered pistons are intended to keep pad wear even.
Key features
- 2-piece, 6-piston, 6T fixed caliper with a Black powder coated finish
- CNC machined from U.S.-sourced forged or billet aluminum
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- 1-piece slotted and zinc-plated 13.5 inch vented rotor
- Curved vane rotor design that Baer says improves cooling and reduces brake fade
- Mounting brackets, stainless braided hoses and hardware all included
Wheel clearance and fit checks
Wheel clearance matters more with larger calipers. Before mounting a new wheel, check the inner barrel and offset against the caliper body and the spoke clearance around the rotor hat. Rubbing can appear only under compression on rough trails, so test steering lock and suspension travel after fitting.
Rotor size also affects clearance and overall braking balance. Keep the same rotor and caliper pairing on each axle, and avoid mixing pad compounds across the front. Inspect the rotor hat for cracks and check that the wheel studs and lug nuts seat properly on the hub face.
- Test steering through full lock with the wheel mounted
- Confirm the tire does not contact the caliper at full suspension travel
- Recheck lug nut tightness after the first few drives

Vehicle fitment
Fits the 2007–2018 Jeep Wrangler (JK), the 2018–2025 Jeep Wrangler (JL) and the 2020–2025 Jeep Gladiator (JT), each with factory spindles and hubs. Applications are Jeep Wrangler 07-17, Jeep Wrangler 18-25 and Jeep Gladiator 20-25.
Older Wrangler generations such as the TJ and LJ are outside this fitment, as are Gladiators built before 2020. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The system relies on factory spindles and hubs, so verify that setup first. Stock-height hoses are supplied, and lifted Jeeps may need longer ones. JK models from 2007–2018 with a 1.00 inch master cylinder should add the Mopar upgrade P/N P5160050AB. Baer cannot guarantee fit with every aftermarket wheel, so compare the O084M template against the wheel you plan to run.
What’s included
The package covers the 6T caliper, the 13.5 inch rotor, mounting brackets, stainless braided hoses and hardware.
Not included: the Mopar Performance Booster/Master Cylinder P/N P5160050AB, which applies to some 2007–2018 Jeep JK vehicles.
