Overview
The Baer Brakes 4401006S is a Pro Plus 6P front brake system in Silver for the 2018 Jeep Wrangler JK, the 2018–2025 Jeep Wrangler JL and the 2020–2025 Jeep Gladiator JT, all with factory spindles and hubs. It uses a 6-piston caliper on a 14.0 inch 2-piece rotor, and the pad type is D0731.
The Pro Plus pairs a 2-piece, 6-piston caliper with a rotor that is slotted, drilled and zinc plated and mounted to a billet aluminum hat. The rotor arrives pre-assembled with NAS high grade stainless hardware, and the design calls for wheels of 18 inch or larger.
Key features
- 2-piece, 6-piston, 6P fixed caliper with a Silver powder coated finish
- Caliper manufactured in Phoenix, Az
- 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
- 2-piece slotted, drilled and zinc-plated rotor with billet aluminum hat
- Rotor and mounting hardware pre-assembled with NAS high grade stainless fasteners
Hub and bearing checks
Hub and bearing condition affects how a brake rotor runs. A worn wheel bearing can cause wobble, uneven pad contact and a pulse through the pedal, even when the brake parts are new. Before mounting a new rotor, check for play at the hub by rocking the wheel at the top and bottom, and inspect the seal for leaks.
Pre-assembled rotors reduce setup steps, but the hub face still needs to be clean and free of rust before installation. Remove any corrosion and check that the mating surface is flat. Hardware should be fully seated, and lug nuts should be tightened in a star pattern once the wheel is on.
- Check wheel bearing play before installing new rotors
- Clean hub mounting faces of rust and debris
- Replace seals that show leakage

Vehicle fitment
The manufacturer fitment list names the 2018 Jeep Wrangler (JK), the 2018–2025 Jeep Wrangler (JL) and the 2020–2025 Jeep Gladiator (JT). Application lines read Jeep Gladiator 20-25 and Jeep Wrangler 18-25, and the kit assumes factory spindles and hubs.
Other Wrangler JK model years, such as 2007 through 2017, are not in this list, and earlier Wrangler generations are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Brake hoses are not part of this kit, so supply hoses that suit the 14.0 inch Pro Plus setup. The rotors are pre-assembled, and Baer recommends comparing the Q082P template with your wheel before mounting, because fit cannot be guaranteed for every wheel style. Brake work should be done by someone experienced with disc brake systems.
What’s included
The kit includes the 6P caliper, the 14.0 inch 2-piece rotor with billet aluminum hat, all mounting brackets and the hardware.
Not included: Brake hoses are not included in the kit.
