Overview
The Baer Brakes 4402007HO-2 is a Hugger Orange SS4 rear brake system for 2007–2018 Jeep Wrangler JK, 2018–2025 Jeep Wrangler JL and 2020–2025 Jeep Gladiator vehicles with the original rear end. The 4-piston S4 caliper uses a Hugger Orange finish and clamps a one-piece, 13-inch vented rotor.
Hard anodized aluminum pistons run on stainless steel abutments, and noise suppression clips are part of the caliper build. Dual seals guard against dust, weather and pressure. The rotor is a zinc-plated, slotted one-piece design that uses DR1-C pads. Rotors arrive pre-assembled with NAS high grade stainless hardware, and all mounting brackets and hardware come with the kit. The 13-inch SS4 Plus fits most wheels 17 inches or larger, but wheel styles vary, so compare the S193H template to your wheel before ordering.

Keeping the brakes in shape
Brake rotors and pads wear from heat and friction, and the rear axle sees less load than the front, so rear pads often last longer than the fronts on road use. Off-road driving changes that pattern. Mud, sand and rock dust work into the caliper and pad area, and steep descents can heat the rotor more than a highway run does.
Keeping the system in shape is mostly routine checking. Wipe grit from the caliper body after muddy runs, look at the rotor face for deep grooves, and confirm the pads still have usable material. A soft or spongy pedal is a sign to inspect the hydraulic lines and fluid level first, since air or leaks can mimic worn pads.
- Rinse mud and sand from calipers after trail use
- Measure pad thickness at each service interval
- Check the rotor face for heat cracks or deep scoring
- Look for fluid seepage at hose fittings

Installation notes
Rear rotor and caliper replacement on these Jeeps is best left to a technician comfortable with hydraulic brake lines. The parking brake is re-used rather than replaced. Hoses are not included, so inspect the current hoses first. Confirm rotor clearance behind a 17.0-inch wheel with the S193H template.
