2000 Chevrolet Astro Brake Disc Parts Questions & Experts Answers

• Q: Under What Conditions Should Brake Discs Be Serviced and Repaired on 2000 Chevrolet Astro?

  A: Refraining from brake rotor refinishing must happen when the braking surface shows intense damage exceeding 1.5 mm (0.060 inch) or when pulsation reveals rotor thickness exceeds 0.025 mm (0.001 inch) or corrosion extents beyond the surface. One must use accu turns as an off-vehicle brake lathe while pro-cut functions on the vehicle. The j39144 composite rotor mounting adapter and the resurfacing tools j41013 rotor and j42450-a wheel hub alongside the j39544-kit torque socket set and other required hardware make up all necessary equipment. The procedure starts with caliper support while you set markers to the rotor that help identify its spot on the hub. Degrease the mating surface of the rotor and flange with the j42450-a before measuring its minimal spot with the micrometer; a point less than the spec requires a new rotor instead of resurfacing. Dust down the rotor/hub mating surfaces along with rotor/wheel contact zones by using the j41013 device. Affix the brake rotor onto the brake lathe by utilizing j39144 tool for composite rotors or directly mount it onto the vehicle if using pro-cut while keeping it aligned with the existing marks. The lathe manufacturer's specifications must guide rotor refinishing steps because a perfect finish helps prevent stopping problems. When the machining process ends use 120 grit aluminum oxide sandpaper and non-directional rotor finishers to make the braking surfaces non-directional before cleaning them with denatured alcohol or suitable brake cleaner. After finishing the process replace the brake rotor by installing the caliper and validating the alignment throughout the installation. The proper procedure to protect brakes from damage requires using the j39544-kit torque socket or torque wrench to achieve uniform wheel nut tightening which reaches the recommended torque value.
