Front pads on the 4Runner run 40,000–60,000 miles in mixed driving; the job takes under 2 hours, costs $120 for pads-only or $350 with new OEM rotors, and the caliper bracket bolts torque to 91 ft-lb.
The 4Runner's front brake setup is conventional sliding-caliper, single-piston-per-side — the same architecture Toyota has used on body-on-frame trucks for decades. That's a good thing: parts are common, the procedure hasn't changed across the 4th gen (2003–2009) and 5th gen (2010–2024), and you can usually do the job with hand tools you already own.
Pads first, rotors when needed. Toyota's spec is to replace rotors when they fall below 27mm (factory thickness is 28mm on most years). In practice, you'll get one set of pads on a healthy rotor before warpage or scoring forces a replacement. If you off-road and dunk the rotors in water — creek crossings, mud — they may warp at 30,000 miles even when pad life is still good. That's not a defect, it's heat-cycling.
Pad choice matters for what you'll feel pedal-side. OEM Toyota pads (Advics or Akebono OE) are the quietest and produce moderate dust. Akebono ProACT ceramics produce less dust than OE and feel nearly identical. Avoid the bargain semi-metallic pads at chain auto parts stores — they bite harder cold but they grind your rotors faster and squeal in stop-and-go. For loaded overlanding rigs running 33s, step up to EBC Yellowstuff or Powerstop Z36 — they tolerate sustained heat from steep descents better than OE.
Rotors: stick with Toyota OEM or Centric Premium. Drilled-and-slotted from Powerstop or R1 Concepts look aggressive but offer zero performance benefit for a 4,800-lb truck on the street — the drill holes become stress risers and the slots wear pads faster. If you want better fade resistance, the upgrade path is bigger brakes (Powerbrake X-Line for 6th gen Tacoma calipers swap) not "performance" rotors on stock calipers.
The two caliper bracket bolts (19mm, 91 ft-lb) and the two caliper slider bolts (14mm, 30 ft-lb) are the critical torques. Get either wrong and the caliper either binds (rotor drag, premature pad wear, hot wheels) or works loose (vibration, eventual failure). Always use a torque wrench on brakes — they're life-safety hardware.
