2002 Chevrolet Astro Brake Disc Parts Questions & Experts Answers

• Q: How to service and repair the Brake Disc on 2002 Chevrolet Astro?

  A: First, gather the following tools to service and repair the Brake Disc: composite disc mounting adapter (J 39144), disc resurfacing kit (J 41013), wheel hub resurfacing kit (J 42450-A), and complete torque socket set (10 Pieces) (J 39544-KIT). These are just a few of the many items that are necessary to solve one or more problems. It should be noted that the attached photos indicate the subject of these additional items. Remove and support the brake caliper while marking the Brake Disc marking to identify with its relationship to the hub. Remove any rust or foreign matter from the mating surface of the disc and flange by using the wheel hub resurfacing kit (J 42450-A) to avoid increased lateral runout and brake pulsation. Take the brake and quantify its thinnest point with a micrometer; if it is thicker than the minimum thickness, enhance the disc instead of refurbishing. The disc/hub flange and disc/wheel mating surfaces should be cleaned from rust using the disc resurfacing kit (J 41013). If performing the machining with the help of the accu turn (off-vehicle) brake lathe, use the composite disc mounting adapter (J 39144), mount the disc; if using the pro-cut (on-vehicle) brake lathe, align the disc to the hub using the earlier made marks. Refinished and create a non directional braking surface using 120 grit aluminum oxide sandpaper and a non directional disc coarse finisher and clean braking surfaces in same manner using denatured alcohol or brake cleaner suitable. Reinstall your Brake Disc, make it well aligned, and install the brake caliper. Lastly, use the appropriate torque socket from the complete torque socket set (J 39544-KIT) to snug up the wheel nuts uniformly in the correct specification without causing brake pulsation and disc damage.
