What to Know About Gmc Acadia Brake Replacement

Understanding GMC Acadia brake replacement matters because it directly affects stopping distance, brake pedal feel, and how often you replace consumables. Getting it right the first time saves both money and follow-up shop visits.

  • Both generations use 6 lug nuts; first-gen (2007-2016) is 6x132mm, second-gen (2017-present) is 6x120mm.
  • Front rotors are vented on all trims: first-gen run about 12.8 in, second-gen about 12.6 in (321mm).
  • Second-gen rear rotors are about 12.4 in (315mm) and typically vented, though thickness varies by trim.
  • First-gen Acadia uses a drum-in-hat parking brake integrated into the rear rotor hat, actuated by a foot pedal.
  • Second-gen (2017+) uses an electronic parking brake that must be placed in service mode before rear pad work.
  • Lug nuts torque to roughly 140 lb-ft (190 Nm); always tighten in a star pattern to spec.

Spec Chart by Vehicle Class

Vehicle class Pad thickness Rotor thickness
Lug count / bolt pattern 6 lug, 6x132mm 6 lug, 6x120mm
Front rotor ~12.8 in, vented ~12.6 in (321mm), vented
Rear rotor ~12.8 in, vented ~12.4 in (315mm), vented
Parking brake Drum-in-hat, cable Electronic (EPB)
Lug torque ~140 lb-ft ~140 lb-ft

How to Diagnose or Replace

  1. Loosen the lug nuts, lift the corner, secure the vehicle on a jack stand, then remove the wheel.
  2. For 2017-up models, place the electronic parking brake in service mode with a scan tool first.
  3. Remove the two caliper guide-pin bolts, lift off the caliper, and hang it from the coil spring.
  4. Unbolt the caliper bracket, then slide the old rotor off the hub after removing any retaining clip.
  5. Clean the hub face, mount the new rotor, and reinstall the bracket to spec.
  6. Compress the piston, fit new pads, reinstall the caliper, and torque the guide-pin bolts.
  7. Reinstall the wheel, torque lugs to about 140 lb-ft in a star pattern, and bed the brakes.

Once diagnosis is complete, order the exact replacement parts for your vehicle - fitment matters. Related GMC Acadia brake replacement products are listed in the next section.

Cost Breakdown - DIY vs Shop

Job DIY parts only Shop parts and labor
Front pads only $35-$90 $150-$300
Front pads + rotors $120-$280 $350-$550
Rear pads + rotors $110-$260 $300-$500
All four, pads + rotors $220-$500 $650-$1,100

DIY savings scale with vehicle size and job complexity. A full-size truck brake job saves $450-700 in labor. For most passenger cars, plan on 90-120 minutes per axle for pads only, 2-3 hours for pads plus rotors.

Install Tips - Where Most DIYers Go Wrong

  • On 2017-up Acadias, retract the electronic parking brake with a scan tool before removing rear pads to avoid motor damage.
  • Apply a thin film of high-temp grease to caliper slide pins and pad ears, keeping it off the rotor face.
  • Torque lug nuts to about 140 lb-ft in a star pattern, then re-torque after roughly 50-100 miles.
