Overview
The Baer Brakes 4402007GG-2 is a rear brake system kit built around the SS4 caliper, made for the 2007 to 2018 Jeep Wrangler JK, 2018 to 2025 Wrangler JL and 2020 to 2025 Gladiator JT with the OE rear end. It pairs a 4-piston S4 caliper in graphite gray with a 13 inch one-piece slotted rotor and the DR1-C pad type.
Rotors come pre-assembled with NAS high grade stainless hardware, and all mounting brackets and hardware are included. The kit is sold as a complete set for these Jeep models. The 13 inch SS4 Plus fits most 17 inch or larger wheels, but fit depends on the wheel style, so compare the S193H template to your wheel before ordering.

Trail and road use
Graphite gray is a finish choice only. The caliper’s function is set by its piston count, floating design and the rotor it clamps, so the color does not change how the kit performs. Many owners pick a finish to match wheels or a build theme, which is a fair reason as long as fitment has been confirmed first.
A rear kit works as part of the whole braking system. Pad material affects bite, fade and dust, so choose pads that suit the way the vehicle is used, whether that means highway commuting, rock crawling or towing. Pair new rear hardware with fresh fluid, since old fluid absorbs moisture and can soften pedal feel under heavy braking.
- Choose pads for your main type of driving
- Replace old brake fluid during the install
- Clean rotor and caliper mounting faces before fitting
- Recheck torque on bracket bolts after the first drive

Installation notes
All mounting brackets and hardware are included, so separate brackets should not be needed. Brake hoses are not included, so plan to source compatible rear hoses separately. Baer recommends comparing the S193H template with your wheel, since Baer cannot guarantee fit for every wheel style or manufacturer.
