Overview
The Baer Brakes 4402001CY is a rear Pro Plus disc brake kit in Comp Yellow, made for Jeep vehicles that use the factory rear end. It fits the 2007–2018 Jeep Wrangler (JK), the 2018–2025 Jeep Wrangler (JL) and the 2020–2025 Jeep Gladiator (JT). The system carries Baer’s 36 inch Pro Plus label.
This rear setup pairs a vented 2-piece rotor, slotted, drilled and zinc plated, with a 6-piston floating caliper. The rotor rides on a billet aluminum hat and arrives pre-assembled with NAS high grade stainless hardware. Brackets and mounting hardware are part of the kit, and Baer names the D0731 pad type for it.
Key features
- Six-piston 6P caliper, built as a 2-piece design, made in Phoenix, Az
- Machined components sourced from US forged or billet aluminum stock
- Comp Yellow powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered piston arrangement intended to limit uneven pad wear
- Dual seals for dust, weather and pressure
- Billet aluminum hat with a slotted, drilled, zinc plated 2-piece rotor
Before you buy
A rear disc brake kit replaces the factory rear rotors and calipers, so the decision starts with confirming that your axle and wheel setup match the kit before any parts are ordered. Because the parking brake is re-used from the OE system, the shoes and hardware that work the park brake stay on the vehicle, and it is worth inspecting them while the rear end is open.
Brake hoses are not supplied, so the old lines should be measured and checked for cracks or swelling before the install. Pads, rotors and calipers wear at different rates, and a new rotor with worn pads can scar the surface quickly, so it is practical to plan pad replacement at the same time.
After installation, bed in the pads and re-check the caliper bolts and bracket fasteners after the first few drives.
- Confirm axle and wheel fit before ordering
- Plan for new brake hoses
- Inspect the parking brake hardware while the rear is apart
- Bed in new pads after installation

Vehicle fitment
Baer’s manufacturer list for the Comp Yellow kit covers the 2020–2025 Jeep Gladiator (JT), the 2018–2025 Jeep Wrangler (JL) and the 2007–2018 Jeep Wrangler (JK), each with the OE rear end.
Vehicles outside those names and years, including other Jeep nameplates, are not on this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Since the parking brake is re-used from the OE system, you will not find new park brake parts in the box. Brake hoses are a separate item, so have them sourced before the install begins. With an 18.0 inch minimum wheel diameter, the Q145P template is the reference for checking wheel clearance.
What’s included
The kit includes the pre-assembled 2-piece rotors with stainless hardware, the Comp Yellow 6-piston calipers, and the brackets and hardware for mounting.
Not included: brake hoses.
