Overview
The Baer Brakes 4401011R-2 is a front 6T brake system kit with six-piston calipers and a 1-piece slotted, zinc-plated rotor. It is made for Jeep Wrangler JK and JL and Gladiator JT vehicles fitted with original-equipment spindles and hubs. It fits the 2007–2018 Wrangler JK, 2018–2025 Wrangler JL and 2020–2025 Gladiator JT.
The rotors use a curved vane design for cooling, consistent braking and reduced brake fade. The caliper is a fixed two-piece, six-piston 6T unit in red powder coat, CNC machined from US-sourced forged or billet aluminum and manufactured in Phoenix, AZ. Staggered pistons help minimize uneven pad wear, and dual seals guard against dust, weather and pressure.
Key features
- Two-piece, six-piston 6T fixed caliper in red powder coat
- CNC machined from US-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 vented rotor
- Curved vane rotor design for cooling and reduced brake fade
- Stainless braided hoses, mounting brackets and hardware included
Pad and rotor wear
A curved vane rotor pushes air through the ventilated section, which helps the friction surface shed heat during repeated stops. Heat is the main factor behind fade on a heavy Jeep, so cooling capacity matters most on long descents and towing. The rotor face should stay flat and free of blue heat spots, which show up when pads and rotors have run hot.
Staggered pistons and dual seals are designed to keep pad contact even and the caliper clean. Even so, pads should be checked on each service because grit trapped behind the pad can scar the rotor. When the rotor shows deep grooves or a lip at the outer edge, replace it along with the pads so the new pads bed in properly.
- Inspect rotor surface after long downhill runs
- Check that pad slides move freely in the bracket
- Replace pads and rotors together when either is worn

Vehicle fitment
It fits the 2007–2018 Jeep Wrangler (JK), 2018–2025 Jeep Wrangler (JL) and 2020–2025 Jeep Gladiator (JT). It is designed for most 17 inch or larger wheels.
It is not made for the Jeep Cherokee (XJ), Grand Cherokee (ZJ or WJ), Liberty (KJ), Comanche or earlier Wrangler YJ and TJ models. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
On 2007–2018 Wrangler JK models with a 1.00 inch master cylinder, upgrading to Mopar Performance booster/master cylinder P/N P5160050AB is advised. The hoses are sized for stock height vehicles, so lifted vehicles may need longer hoses. Wheel fit cannot be guaranteed for every wheel style, so compare the O084M template against your wheel before mounting. Brake work should be done by a qualified technician.
What’s included
The kit includes the 6T caliper assemblies, 1-piece slotted and zinc-plated rotors, all mounting brackets, stainless braided hoses and hardware.
Not included: the Mopar Performance booster/master cylinder P/N P5160050AB that Baer recommends for 2007–2018 JK models with a 1.00 inch master cylinder, and wheels.
