3. Loosen lugs, lift, support on stands, remove the wheel.
4. Remove the caliper bracket bolts and hang the caliper on wire.
5. Swap the rotor and pads, clean the hub, torque everything to spec.

Cost Breakdown - DIY vs Shop

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

• Confirm rotor size BEFORE ordering. 12.99 vs 13.78 inch is the critical fork
• The rear caliper piston winds back. use the correct tool, do not press it
• Torque the caliper bracket bolts to Jeep spec; they are high-torque on the WK2.

Key Takeaways

• The 2011-2020 Jeep Grand Cherokee (and its Dodge Durango twin) came with two different front rotor sizes: 12.99 inch (330 mm) on V6 models and 13.78 inch (350 mm) on 5.7L V8 and SRT models. Measure your removed rotor before ordering - the wrong size will not fit.
• Measure friction material and rotor thickness at every tire rotation - catches wear before it becomes damage.
