If you're looking to upgrade your Jeep's braking system, let me tell you about the Baer SS4 rear brake kit. This isn't just another set of calipers; it's a serious piece of gear that brings some real stopping power to your ride. You get a robust S4 4-piston caliper paired with a solid 12.2-inch one-piece rotor that’s not just slotted but also drilled and zinc plated for durability. Plus, it’s D.O.T. compliant, so you know it’s built to handle the elements with dust and weather seals that keep everything clean.
Fitment:
- Designed specifically for the 2007-2017 Jeep JK rear setup.
Why the SS4 is Worth It:
- The 12.2-inch rotor is directionally vaned, which means better cooling and performance under pressure.
- If you're running our Track4 front brake system, this rear kit is a perfect match—talk about a cohesive look!
- It shares the same brake shoe as the late model Corvette C5/C6, so you know you're getting quality parts.
- Everything you need is included—fittings, hardware, the whole shebang.
- Those 12.2-inch rotors fit some 15-inch wheels and most 16-inch ones, but definitely check with a template to be sure.
Features of the S4 Caliper:
- Four 10mm cross bolts give it maximum stiffness, so you know it’s not flexing under heavy use.
- Stainless steel abutments and noise suppression springs keep things quiet and smooth.
- Hard anodized aluminum pistons are built to last.
- Internal crossover design helps with consistent pressure across the caliper.
- Dual seals (dust, weather, and pressure) meet D.O.T. specs, ensuring reliable performance.
- Each caliper has a machined logo that’s hand-painted—little touches like that make a difference.
- Uses a common 4-piston pad for easy replacements (P/N DR1), so no hunting around for obscure parts.
- Comes in a silver powder coat finish, with standard colors like red, black, or silver, plus custom options if you want something unique.
- Available for both front and rear, so you can keep that aesthetic consistent across your Jeep.
- For C-clip style axles, you get Baer’s Verislide self-centering brackets included.
- Correct banjo-style fittings are used—no pipe thread nonsense here.
- And best of all, it’s 100% made in the USA with materials sourced right here. Support local!
