Big brake kits
Stock brakes weren’t designed for the ST.
Factory front calipers are shared with the base Edge. The ST’s extra weight, extra power, and the way you drive it all land on those same pads. Three kits below — calipers, two-piece floating rotors, OE-fit brackets, stainless braided lines, every bolt. Bolt-on, no fabrication.

The first four questions every owner asks.
Does the rear kit work with the factory electric parking brake?
Yes. The rear 4-piston kit is engineered around the Explorer ST’s factory EPB module — no FORScan coding, no extra harness, no aftermarket actuator. Bolt it on, bleed the system, and the parking brake works exactly as it did from the factory.
Will my current wheels clear the rotor?
The 380 mm rotors clear factory and most aftermarket 19" wheels. The 405 mm front rotors need a 20" wheel or larger. The configurator greys out incompatible rotor sizes once you tell it your wheel diameter, so you can’t accidentally buy a kit that won’t fit.
What’s actually included in the kit price?
Calipers, two-piece floating rotors, OE-fit brackets, stainless steel braided lines, and every piece of hardware required to bolt the kit on. You don’t need to add lines, brackets, or hardware to your cart — everything ships in the same box.
Can I get a caliper or wheel color you don’t list?
Yes — both configurators have a “Request a custom color” tile. Upload a swatch or paint code and we’ll quote it. Custom colors add lead time and are quoted per build.
