Front pads and rotors take 90 minutes; rears another 60. Caliper bracket bolts are 110 ft-lb, slide pins are 26 ft-lb, lugs are 130 ft-lb. Don't reuse worn slide pin boots — torn boots cause uneven pad wear within 5,000 miles.
JL Wrangler brakes are larger than JK across the lineup — the front rotor went from 12.9" on JK Sport to 13.0" Sport/13.4" Rubicon on JL. The system is otherwise conventional floating caliper with single-piston front and rear. Pad and rotor service is straightforward once you understand the bracket vs slide pin distinction.
**Pad choice.** OE Mopar pads are quiet but dust-heavy. Akebono ACT-series ceramic pads stay clean and bite well below 1,000°F — the right choice for daily-drivers and mild trail use. Hawk LTS gives more cold bite for tow rigs. Avoid no-name pads from auction sites; they'll glaze and squeal within 6 months.
**Rotor decision.** Rotors are sacrificial. If yours have <0.030" of useful thickness left (verify with a micrometer against the minimum stamped on the rotor hat), replace them. Centric Premium and Bosch QuietCast are both quiet and last 50K+ miles. Slotted/drilled rotors look aggressive but offer no benefit for the JL's weight class and crack faster.
**Slide pins matter more than pads.** A torn slide pin boot lets sand and water into the pin bore. The caliper then sticks on one side, the inboard pad wears faster than outboard, and you replace pads at half life. Inspect both pins every brake service. Re-grease with high-temp synthetic brake grease — never wheel bearing grease (it melts).
