  Q: Is a Hub-Mounted Lathe Recommended for Machining the Brake Rotor on Jeep Commander?

  A:

  Using an on-vehicle hub mounted lathe is the best method for machining the brake disc, because it ensures it is true to the hub and bearing of the vehicle. A scored or worn braking disc needs to be machined and to do this, two cutter heads must be used at the same time to work both sides. You need to clean the disc mounting surface before setting it on the lathe, as equipment doing just one side may create a victory disc. Any brake disc that does not meet the minimum thickness standard must be changed out, before or after the machining process.

  Q: How to Service and Repair a Front Brake Rotor on Jeep Commander?

  A:

  Before starting the service, put the rotor on the hub studs. After that, fix the caliper adapter to the knuckle using the adapter bolts and torque them to 169 Nm (125 ft. lbs.). Be sure that the caliper slide pins are not dirty and receive a light layer of oil before moving forward. At that point, fit the caliper to the caliper adapter and tighten the bolts until you reach 44 Nm (32 ft. lbs.). Elevate one end of the slide pin boot, so both ends have the same pressure and check that it still covers the slide pin once you let go. When that step is done, install the wheel and tire assembly, take off the support and bring the vehicle down. Next, ground the vehicle by pumping the brake pedal and pressing the caliper pistons until the Brake Pads are pressed firmly onto the brake disc.
