TJ front pads run 30,000–45,000 miles depending on terrain and gear. The 1997–2002 TJ uses a 3/8" hex bit on the caliper slider; the 2003+ Rubicon and LJ use a slightly larger bolt head. Caliper slider torque is 11–13 ft-lb — straightforward to strip.
The TJ front brake setup is single-piston floating caliper on vented rotors, same general layout as the XJ Cherokee it shares an axle with. Two slider pins hold the caliper; two large bracket bolts hold the bracket to the steering knuckle. What makes the TJ slightly different from the XJ is the slider bolts use a 3/8" hex (Allen) head on 1997–2002 trucks — you'll need a hex bit socket, not a regular hex socket, to break them loose without rounding them.
A note on tools: many TJ owners discover mid-job that their breaker bar set is missing the 3/8" hex bit. Pick one up before starting. The slider bolts often blue-Loctite from the factory and don't always come loose easily — a quality bit and a breaker bar beat a stripped slider every time.
Pad recommendations for the TJ skew toward heavier compounds than the XJ because TJs are typically lifted on bigger tires more aggressively. Stock pads from Mopar (PN 5018572AB) are fine for a stock-tire Sport. Anything past 33s, add weight, or tow occasionally — go to Powerstop Z36 or EBC Yellowstuff. The TJ's brake system is the same hardware as a much lighter vehicle; the only way to make it deal with 35s and a winch bumper is harder pad compound and a heavier rotor.
Rotor choice: Centric Premium ($40 each) or Powerstop Evolution ($45 each) are solid stock-replacement options that often outlast OEM. Skip the cheap blank rotors from chain auto parts stores — they warp within 5,000 miles on a daily-driven TJ. Mopar OEM rotors are decent but expensive; Centric Premium gives 90% of the durability for half the price.
The TJ caliper slider bolts are the most-stripped bolts on the front end. Chrysler spec is 11–13 ft-lb. That feels finger-tight to anyone used to lug nuts. Use a torque wrench. Over-torque and you either snap the bolt or strip the bracket threads — both leave you with a non-driveable Jeep until you helicoil the bracket or find a new one.
