Overview
The Baer Brakes 4402001GB is a rear Pro Plus brake kit in Grabber Blue, intended for the factory rear end of Jeep Wrangler and Gladiator vehicles. The manufacturer list covers the 2007–2018 Jeep Wrangler (JK), the 2018–2025 Jeep Wrangler (JL) and the 2020–2025 Jeep Gladiator (JT). The system is marketed as a 36 inch Pro Plus design.
Baer built this rear system around a vented 2-piece rotor that is slotted, drilled and zinc plated, with a billet aluminum hat. The rotors come assembled with stainless hardware. The brackets and the hardware to mount them come with the kit, but brake hoses do not, and the park brake stays on the OE setup.
Key features
- Six-piston caliper, designated 6P, manufactured in Phoenix, Az
- Grabber Blue powder coated finish
- Billet aluminum hat on the 2-piece rotor
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals rated for dust, weather and pressure
- Staggered pistons designed to limit uneven pad wear
- Zinc plated rotor surface, slotted and drilled
Caliper and pad replacement
Replacing pads on a floating caliper system starts with inspecting the slide pins and their rubber boots. Pins that bind or carry dry grease cause the caliper to drag, which wears one pad faster than the other and can heat the rotor unevenly. Clean the pins, check the boots for tears, and reapply a high temperature caliper lubricant to the contact points.
Piston retraction should be done slowly, with the reservoir watched so fluid does not overflow. Keep grease and lubricant away from the rotor and pad friction surfaces, since contamination reduces braking and can cause squeal that does not go away after the pads are seated.
- Slide pins that move freely without grease buildup
- Boots intact and seated in their grooves
- Pad backing plates free of rust
- Rotor surface clean before the new pads go on

Vehicle fitment
Baer’s manufacturer list for the Grabber Blue kit names 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.
Models not named in that list, such as other Jeep nameplates, are not shown as covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The kit is set up for the factory park brake, which is re-used from the OE system, so no park brake hardware is supplied. With an 18.0 inch minimum wheel diameter, run the Q145P template against your wheel to confirm clearance before you finalize the wheel choice.
What’s included
The kit includes the pre-assembled 2-piece rotors with stainless hardware, the Grabber Blue 6-piston calipers, and the brackets and hardware for the install.
Not included: brake hoses.
