Overview
The Baer Brakes 4401001S is a silver Pro Plus front brake kit made for the 2007–2017 Jeep Wrangler JK with original-equipment spindles and hubs. It pairs a six-piston fixed caliper with a 14-inch two-piece vented rotor, and the template for this kit is Q085P.
The silver powder-coated caliper has stainless steel pistons and noise suppression clips, and it is manufactured in Phoenix, Arizona. The two-piece rotor is slotted, drilled and zinc plated on a billet aluminum hat. This kit is the JK version intended for a 2007–2017 Wrangler.
Key features
- Six-piston fixed caliper in silver powder coat
- Staggered pistons intended to minimize uneven pad wear
- Dual seals guarding against dust, weather and pressure
- Two-piece slotted, drilled and zinc-plated rotor on a billet aluminum hat
- CNC machined caliper body from US-sourced forged or billet aluminum
- T compliant dust and weather seals are fitted, and the pads are D0731 type.
Working with JK brake parts
The Wrangler JK uses a front axle and steering setup that is shared across several model years, so a brake upgrade goes most smoothly when the old parts come off in a clear order. Photograph the caliper bracket bolts and hose routing before disassembly. While the wheels are off, inspect the front wheel bearings and hubs, since a loose or worn bearing affects rotor runout and pedal feel.
Pads should match the caliper design, so keep that pairing in mind when replacing them later. Brake fluid absorbs moisture over time, so changing it after a major brake job helps keep the system responsive. If the pedal feels soft, check for air in the lines or a leak at a fitting before driving the vehicle.
- Photograph bracket and hose routing before removal
- Inspect wheel bearings and hubs with wheels off
- Match pad type to the caliper
- Flush and refill fluid after the job

Vehicle fitment
It fits the 2007–2017 Jeep Wrangler JK. The application is Jeep Wrangler 07-17, and original-equipment spindles and hubs are required.
Does not cover the 2018–2025 Jeep Wrangler (JL) or the 2020–2025 Jeep Gladiator. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor comes with its hat already assembled, so the work centers on the caliper and bracket mounting. Brake hoses are not supplied, so confirm a compatible hose for a 2007–2017 JK before starting. Use the Q085P template to check wheel clearance, since Baer cannot promise fit to every wheel style.
What’s included
The kit includes the six-piston silver caliper, the two-piece rotor with hat, and the mounting brackets and hardware.
Not included: brake hoses.
