Overview
The Baer Brakes 4401011S-2 is a silver front brake kit for the Jeep Wrangler JK, Wrangler JL and Gladiator JT, built around a 6T six-piston caliper and a 13.5 inch vented rotor. It is designed to work with the factory front spindles and hubs.
The kit uses the D1247 pad with semi-metallic friction material and a one-piece slotted, zinc plated rotor. Steel braided hoses, mounting brackets and hardware come with the package. The calipers are CNC machined from forged or billet aluminum with a powder coated finish. Use the O084M template to check wheel clearance against the wheel you plan to use.
Key features
- One-piece slotted and zinc plated vented rotor, 13.5 inch outside diameter
- Silver powder coated six-piston 6T caliper
- Stainless steel pistons, abutments and noise clips
- Staggered piston layout intended to even out pad wear
- Dust and weather seals are T compliant.
- DOT approved steel braided brake hoses
- D1247 pad type with semi-metallic friction material
Choosing front brake parts
Front brakes handle most of the stopping force on a Jeep, and they work hardest on steep descents, while towing and on rough trail sections where repeated braking heats the rotors. A front kit with a vented rotor and a multi-piston caliper helps manage that heat. Semi-metallic friction material is often chosen for firmer bite under higher loads, though it can be noisier and wear rotors faster than ceramic pads.
When choosing or reviewing front parts, consider tire size, wheel offset and suspension height, since these affect clearance and hose length. Lifted vehicles often need longer brake lines, and a new master cylinder or booster may be needed when the factory setup has changed. Inspect the spindle, hub bearings and wheel studs at the same time, because worn bearings or a warped rotor can cause pulsation even with new parts.
- Verify wheel clearance against the caliper before mounting
- Bed in new pads and rotors gradually
- Follow the brake fluid service schedule for the vehicle
- Check hose routing for contact with suspension parts

Vehicle fitment
It fits the 2007–2018 Jeep Wrangler (JK), the 2018–2025 Jeep Wrangler (JL) and the 2020–2025 Jeep Gladiator (JT). Wrangler YJ, TJ and LJ models and Gladiator years before 2020 are not covered. Confirm your vehicle’s year, model and trim before ordering.
Wrangler YJ, TJ and LJ models and Gladiator years before 2020 are not on this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The steel braided hoses are sized for stock height vehicles, so lifted Jeeps may need longer hoses. Baer recommends upgrading to Mopar Performance Booster/Master Cylinder P/N P5160050AB on 2007–2018 JK models that have a 1.00 inch master cylinder.
Front brake work should be done by a qualified technician with the vehicle safely supported on stands.
What’s included
The package includes the silver 6T calipers, the one-piece rotors, steel braided hoses, mounting brackets and hardware.
Not included: factory spindles and hubs, which this kit is designed to use.
